Kings Canyon National Park

Climate

According to the Köppen climate classification system, most of Kings Canyon National Park has a warm-summer Mediterranean climate (Csb), with only the lowest of elevations having a hot-summer Mediterranean climate (Csa). According to the United States Department of Agriculture, the Plant Hardiness zone at Cedar Grove Visitor Center at 4,613 ft (1,406 m) elevation is 8a with an average annual extreme minimum temperature of 12.3 °F (−10.9 °C).

Plants and wildlife

Over 1,200 species of plants occur in Kings Canyon and Sequoia Parks, representing about 20 percent of all plant species in the state. In 1976, Kings Canyon was designated by UNESCO as part of the Sequoia-Kings Canyon Biosphere Reserve. Due to the large range in elevation, the park is characterized by several major plant communities. At lower elevations the park touches the fairly dry Sierra foothill zone which mostly consists of chaparral, brush and shrubs. Oaks, sycamores, willows and various hardwoods are often found along streams and springs at lower elevations.

At middle elevations, most of the park consists of montane mixed-conifer forests: ponderosa pine, incense cedar, white fir, sugar pine and scattered groves of giant sequoias prevail in areas such as Cedar Grove and the mid-elevation slopes around Grant Grove. In Kings Canyon, which runs almost due east to west, there is a marked difference between the north wall – which is hotter and drier due to receiving more sunlight – and the more cool, shaded south wall which is more heavily forested. Further up, approaching the subalpine zone, red fir and lodgepole pine are found in increasing numbers; whitebark pine, mountain hemlock and foxtail pine dominate in areas approaching the tree line. A total of 202,430 acres (81,920 ha) of old-growth forests are shared by Sequoia and Kings Canyon National Parks.

Although its sister park to the south, Sequoia, is better known for its giant sequoias, Kings Canyon also has large stands of sequoias – including General Grant, the second largest tree on Earth, in the middle of General Grant Grove. The Redwood Mountain Grove, located a short distance further south, is the largest surviving sequoia grove in the world, covering more than 2,500 acres (1,000 ha); it also has the tallest known sequoia, at 311 feet (95 m). The Converse Basin Grove, located just outside the park boundary, is believed to have once been more than twice as large, but was almost completely clear-cut in the late 1800s. Many of the sequoia groves destroyed by logging, such as the Big Stump Grove, have begun to regenerate, a process that will take many hundreds of years.

The forests provide habitat to many mammal species such as mule deer, Sierra Nevada bighorn sheep, mountain lions and black bears, and a diversity of bird and reptile species. The Park Service is involved in restoring the population of bighorn sheep, which are considered endangered in the area; in 2014 several bighorns were released into the Sequoia-Kings Canyon area. Grizzly bears originally roamed the park as well, but were hunted to extinction by the early 1900s. The forks of the Kings River at these middle and lower elevations are also well known for their wild trout; the Kings is known as "one of the finest large trout fisheries in the state".

In the high alpine country, plant communities are mostly meadows, herbs and shrubs with some scattered groves of foxtail pine and stunted whitebark pine. Trees often create krummholtz formations, or a stunted, deformed growth pattern characterized by branches closely hugging the ground. Talus slopes are home to small mammals such as pikas and yellow-bellied marmots. Birds such as gray-crowned rosy finches and American pipits, and sensitive amphibian species such as mountain yellow-legged frogs and Yosemite toads, feed on insects near alpine lakes and wetlands. Larger animals such as bears may venture into the alpine zone in search of food (a behavior now exacerbated by improper disposal of waste by campers), but do not winter there.

Human impacts and management

Although most of the park is now designated wilderness, human activities have significantly modified the ecology of the area ever since Native American times. In order to clear areas for hunting game and to encourage the germination of certain plants, Native Americans set controlled burns in areas of overgrown brush and grass. During the early 20th century, ""complete fire suppression" policy led to a great build-up of debris and tinder in the park's forests. By the 1960s it became apparent that this was interfering with the reproductive cycle of the park's sequoias, whose bark is fire resistant but require regular fires to clear away competing growth such as white firs. In 1963, scientists deliberately set fire to part of the Redwood Mountain Grove, the first fire in any of the park's sequoia groves for 75 years. Thousands of new sequoia seedlings germinated. The success of the experiment led to the establishment of the park's first long-term prescribed burn program in 1972.

A major source of damage to the park in the late 19th century and early 20th century was summer livestock grazing, particularly sheep, in areas such as Tehipite Valley and the Roaring River valley (although sheep never entered Cedar Grove, due to the difficulty of accessing the bottom of Kings Canyon before Highway 180 was constructed). Ranchers drove their herds up into the Sierra Nevada to escape the drought and heat of the San Joaquin Valley. Meadows were trampled by thousands of hooves, leading to increased erosion and watershed degradation. Grizzly bears and wolves which preyed on livestock were shot, trapped and poisoned in large numbers, extirpating them from the Sierra by the early 1900s.

Although the Sierra Forest Reserve, including what would become Kings Canyon and Sequoia National Parks, was established in 1893, as many as half a million sheep were illegally grazed there. In 1917 the federal government began to crack down on illegal grazing and established a system of regulated management and range restoration, before sheep were banned from Kings Canyon altogether following the park's creation in 1940. Livestock grazing is still allowed in some national forest lands around the park. Occasionally hikers may come across gated drift fences in the wilderness designed to control livestock movement. Visitors must close all gates behind them to prevent livestock from wandering into protected areas.

The decline of natural predators in the early 1900s led to a huge spike in the deer population, which further rose due to park visitors feeding them. Ultimately, this led to overgrazing and the vegetation understory was nearly eliminated in large areas of the park. When the park was expanded in 1940, the Park Service began shooting deer in an effort to reduce the size of the herd. Although the culling reduced deer numbers to a more ecologically stable level, the program was criticized for its reliance on brute force rather than more "hands-off" methods, such as re-introducing predators. Today, the only stock allowed in the park are pack horses and mules, which are only permitted in certain areas along major trails, and usually not early in the season in order to protect meadows in the spring while they are wet and soft.

The park continues to host a healthy population of black bears, which are typically not aggressive towards humans, but have a tendency to steal human food. The Park Service has placed bear lockers in campgrounds, required the use of bear canisters and attempted to relocate bears away from heavily visited areas. This has been successful in the backcountry, where bears have largely ceased to associate backpackers with food, but remains an issue near developed campgrounds. Visitors are encouraged to store all food and scented items in lockers, and dispose of trash in bearproof garbage cans. However, rangers are still sometimes forced to kill "problem bears" who become habituated to human food.

Human history

Indigenous peoples

People have inhabited Kings Canyon National Park for about 6,000–7,000 years. The Owens Valley Paiutes (also known as the Eastern Monos) visited the region from their homeland east of the Sierra Nevada, around Mono Lake. The Paiutes mainly used acorns for food, as well as deer and other small animals. They created trade routes connecting the Owens Valley with the Central Valley west of the Sierra Nevada. The Yokuts lived in the Central Valley and also ventured into the mountains during summer to collect plants, hunt game, and trade. Because of the inhospitable winter climate, they did not establish permanent villages in the high country. Prior to European contact, the Yokut population numbered between 15,000 and 20,000, and the Monos about 6,000.

Around the 1500s AD, some of the Eastern Mono migrated across the Sierra Nevada into the Central Valley, where they created settlements adjoining Yokuts territory in the Sierra foothills near the Kings River. This group became known as the Monaches, or Western Mono. They eventually divided into as many as six distinct bands, one of which lived in the area near Grant Grove. The native population suffered greatly during the American expansion in the 19th century; a smallpox epidemic killed off most of the Monache in 1862, and very few remain in the area today.

Buffalo Soldiers

The Buffalo Soldiers were African American soldiers in the U.S. Army that was formed in 1866 after the end of the Civil War. Much of their work was in remote areas and highly dangerous. Buffalo Soldiers were stationed in the American frontier protecting settlers, building infrastructure and working in some of the countries first national parks such as Yosemite and Sequoia. The 9th Cavalry of Buffalo Soldiers were stationed in Kings Canyon National Park. Their work here included building, roads, trails, and protecting the park. In many ways, they acted as park rangers before the National Park Service was formed. Many of King Canyons popular sites, trails and tourist attractions were made possible by the Buffalo Soldiers. Led by superintendent Charles Young, the Buffalo soldiers created the first road that led into the forest. They also created the first trail to the top of Mt. Whitney, which is the tallest mountain peak in the lower 48 states.

Early exploration and logging

The early Spanish exploration of California largely bypassed what is now Kings Canyon National Park. In 1805 Gabriel Moraga led an expedition through the Central Valley and crossed what is now the Kings River, bestowing the name Rio de los Santo Reyes (River of the Holy Kings) on the stream. Fur trappers also visited the areas in the 1820s, but most likely did not venture into the high country since beaver were only present at lower elevations. They were followed by prospectors during the California Gold Rush, which began in 1848. However, not much gold, nor other minerals, were discovered in this area. Hale Tharp, a disillusioned gold miner, is credited with the 1858 discovery of Giant Forest in Sequoia National Park, which led to the further exploration and discovery of the other sequoia forests in the area, including Grant Grove.

During the 1860s, a road was built to Grant Grove and many of the sequoias there were logged. The first of several sawmills opened in 1862, and logging operations expanded north and almost entirely leveled Converse Basin, then one of the largest sequoia groves in the world (although the Boole tree, the grove's biggest, was spared). The General Grant tree was discovered by Joseph H. Thomas, a sawmill operator, in 1862. Thomas' business partners, the Gamlin brothers, held a claim to the land surrounding Grant Grove, and their dwelling (built around 1872) has been preserved as a historic site.

During the 1870s a government survey "disclosed the remarkable quality of General Grant Grove, and Israel Gamlin was persuaded to give up his claim so the area could be preserved." However, this did not entirely stop logging in the area – in 1875 a 300-foot (91 m) sequoia was chopped down and a section sent to the Philadelphia Centennial Exposition of 1876. Reportedly, "eastern people refused to accept the exhibit as part of a single tree and called it the 'California Hoax'." The Centennial Stump, and most of the tree, remain as prominent features in Grant Grove: "Ladies from a nearby logging camp used to conduct Sunday school services for their children upon the stump."

Wilderness surveys

The first scientific expedition to the area was the 1864 Whitney Survey, conducted by the Geological Survey of California led by William Brewer. After failed attempts to summit Mount Whitney, the Brewer party descended into the Kings Canyon via Native American paths where "they remarked its resemblance to the Yosemite and were impressed by the enormous height of its cliffs." Although the rugged terrain made travel difficult, they discovered a route up the north wall of the canyon and named several prominent features, including Mount King, Mount Gardiner, the Palisades, and Mount Brewer. From the summit of the peak that would bear his name, Brewer described the view:

Such a landscape! A hundred peaks in sight over thirteen thousand feet—many very sharp—deep canyons, cliffs in every direction almost rival Yosemite, sharp ridges inaccessible to man, on which human foot has never trod—all combined to produce a view of sublimity of which is rarely equaled, one which few are privileged to behold.

Brewer's party left Kings Canyon via Kearsarge Pass where they encountered a group of prospectors led by Thomas Keough. Although details on the Keough expedition are scarce, the miners had been prospecting on the North Fork of the Kings River and were returning to their homes in the Owens Valley, indicating that they must have crossed the Middle Fork – then considered a region impossible to access by white settlers – making them the first non-natives to do so. Around 1869, sheepherder Frank Dusy discovered and named the Middle Fork's Tehipite Valley, and later grazed his sheep there. Aside from such occasional uses, most of the high country remained little visited and mostly unexplored.

Park creation

It was not until John Muir first visited in 1873 that Kings Canyon began receiving public attention. Muir was delighted at the canyon's similarity to Yosemite Valley, as it reinforced his theory that the valleys were carved by massive glaciers during the last ice age. This competed with Josiah Whitney's then-accepted theory that the mountain valleys were formed by earthquakes. Muir's writings on the geology of the park and the magnificence of its sequoia groves led to calls for preservation of the area, and Muir himself continued to lobby for the cause. In 1880 logging claims in the Grant Grove area were suspended by the federal government, in large part due to the political efforts of Colonel George W. Stewart.

In March 1890 a bill (H.R. 8350) was introduced to Congress by Representative William Vandever proposing the creation of Yosemite National Park. Subsequently, some "political intrigue" led to its substitution with H.R. 12187, which also included provisions for a General Grant National Park and the expansion of Sequoia National Park. The origins of this bill remain largely a mystery, although local politicians with an interest in preserving the park were likely involved. Daniel K. Zumwalt, an agent for the Southern Pacific Railroad – which owned many lumber interests in California – may have seen the park as a way to force their competitors in the Sequoia-Kings Canyon area out of business. On October 1, 1890, President Benjamin Harrison signed the bill into law, establishing General Grant National Park – the United States' fourth national park – which today is part of the smaller western section of Kings Canyon National Park.

For many years the primary way for tourists to reach General Grant National Park was the Stephens Grade, a rough wagon road over which a stagecoach operated from Visalia beginning in the early 1900s. Initially, the U.S. Army had to station troops to protect the park from illegal grazing and hunting. Although these eventually ceased to be a problem, the rising number of visitors created its own sanitation and waste issues. In the summer of 1907 about 1,100 people visited the park. A new road reached the General Grant National Park by 1913; that summer, the park saw almost 2,800 tourists. In 1914 the park was turned over from military to civilian control (though the National Park Service was not formally established until 1916).

Park expansion and dam controversy

The future of the park's much larger eastern section remained in doubt for almost fifty years. The backcountry was largely inaccessible and unknown to tourists, requiring several days' journey on horseback through some very rugged terrain. Instead, the area was targeted by water supply and power interests including the city of Los Angeles, who wanted to build hydroelectric dams in Kings Canyon. Due to its heavy flow and long drop – 11,000 feet (3,400 m) in less than 80 miles (130 km) – the Kings River has considerable hydroelectric potential, and reservoirs were proposed for Cedar Grove, Tehipite Valley and Simpson Meadow, among other sites. Development interests blocked legislation that would have made the area a national park, but at the same time, the environmental lobby prevented any of these projects from being built.

In 1935 the Generals Highway was completed connecting Sequoia and General Grant National Parks. In 1939 State Route 180 from Grant Grove to Kings Canyon was finally completed after ten years of construction, finally allowing large numbers of tourists to visit Cedar Grove for the first time. The road was built in part using state prison labor. However, a proposal to extend the state highway over Kearsarge Pass to the Owens Valley was defeated.

Well-graded hiking trails were also extended into the backcountry to replace the rough pack trails used by sheepherders – including the John Muir Trail, completed in 1933 through what is now the eastern edge of Kings Canyon National Park. For many years a tiny ranger station and a few private structures (such as Knapp Cabin) had been the only development in Cedar Grove. Starting in 1937, large campgrounds were developed in Kings Canyon by the U.S. Forest Service, but construction of more permanent facilities was foregone since the area would lie at the bottom of one of the proposed reservoirs.

Ultimately, local opposition to Los Angeles' attempts to secure the Kings River turned into significant political pressure to create a national park, which would prevent any dam projects there. United States Secretary of the Interior Harold Ickes was a major proponent for the expansion of the park, and worked to unite local interests, who had widely different views on how much development should be allowed. Ickes also hired Ansel Adams to photograph and document the area, generating publicity for the preservation movement. However, in order to placate the local irrigation districts – who wanted to leave open the option of reservoirs – Cedar Grove and Tehipite Valley were specifically excluded from the new park. On March 4, 1940, President Franklin D. Roosevelt signed the bill to create Kings Canyon National Park, which added the original General Grant National Park to over 400,000 acres (160,000 ha) of the High Sierra above Cedar Grove.

Later history and additions

The new Kings Canyon administration initially struggled to manage the huge park, which was more than 700 times the size of the original unit at Grant Grove. In the early years staff and expertise were often loaned from Sequoia National Park. In 1943 the administrations of Kings Canyon and Sequoia National Parks were combined, as a cost-saving measure due to World War II. After the war, the arrangement was preserved; today, the two parks are still managed as one. Postwar, visitation jumped enormously, from just over 82,000 in 1945 to 450,000 in 1951. Demand increased for tourist facilities at Cedar Grove, the terminus of the state highway – although the valley was not officially part of the park, having been omitted due to water-development interests. The extension of the road through the valley was controversial, due to potential ecological damage. By 1947 the Park Service had drafted a general plan including tourist lodges, concessions and a pack station.

Then in 1948, Los Angeles unexpectedly re-filed its application to construct dams in Kings Canyon. The Kings River Conservation District (KRCD), representing local water agencies, immediately filed claims on the same sites. KRCD had no intention of constructing dams but hoped to block the possible threat to its water supply. Although the Federal Power Commission rejected Los Angeles' application, as it had prior to 1940, the city repeatedly refiled until 1963, when it was denied by both the California State Water Board and the federal government.

One factor in the project's final failure was that even though the Cedar Grove dam site was outside the park, the project required two additional dams to be built upstream if it were to be economically feasible. However, those sites were now inside the park boundary as designated in 1940. On August 6, 1965, Cedar Grove and Tehipite Valley were finally added to the park, making them permanently off-limits to new dams as well. These annexations (with the exception of a tiny section in 1984, south of Grant Grove) brought Kings Canyon National Park to its present size.

Starting in the 1950s, in response to growing traffic and crowding at national parks, the Park Service implemented Mission 66 which proposed large new visitor developments for Kings Canyon and other parks. This included new visitor centers at Grant Grove and Cedar Grove, electrification and sewage facilities at Cedar Grove, and substantial new accommodations, trails, and parking areas.

After the Cedar Grove development was delayed by the final years of the dam debacle, the Park Service released a new plan in 1972, which included cabins for 260 people, and an 11,000-square-foot (1,000 m²) store and cafeteria complex, hoping to develop the area in a way similar to Yosemite Valley. In 1974 the park saw 1,216,800 visitors, a number that has not been exceeded since. However, by 1975 public hearings showed such an opposition to intense development, that ultimately only a small lodge and store were added to the canyon.

The rising number of visitors to the backcountry – from 8,000 in 1962 to over 44,000 in 1971 – created its own problems in the form of litter, illegal campfires and contact with dangerous wildlife such as bears. In 1966 and 1971 the Park Service proposed, controversially, to designate most of the park as wilderness, which would place much greater restrictions on its use. In 1973 the number of backpackers was first restricted via a quota system. Finally, on September 28, 1984, Congress designated over 85 percent of Kings Canyon and Sequoia National Parks as wilderness. In 1987, the Middle and South Forks of the Kings River were designated Wild and Scenic.

Recreation

Grant Grove, the only vehicular entrance to the park, is 60 miles (97 km) east of Fresno via Highway 180. In addition to Highway 180 from the west, Highway 198, the Generals Highway, provides access from Sequoia National Park in the south. The roads converge in Grant Grove Village, from where Highway 180 continues another 35 miles (56 km) northeast to Cedar Grove. There is no vehicular access from Highway 395 on the eastern side of the park. There is currently no public transportation to Kings Canyon National Park; the Big Trees Shuttle, which originally operated between Sequoia National Park and Grant Grove, is no longer in service.

The National Park Service maintains visitor centers at Grant Grove and Cedar Grove. Grant Grove Village is the most developed part of the park and includes the 36-room John Muir Lodge (the park's largest hotel), visitor cabins, a restaurant and a general store. Cedar Grove also has a small market, but overall the facilities there are much more limited. Barring extreme weather, the Grant Grove section is open year-round; Cedar Grove is closed in winter. Highway 180 is plowed only as far as Princess Meadow, the junction with the Hume Lake Road, which remains open to Hume Lake in winter.

Due to its limited road access, Kings Canyon receives many fewer visitors than its neighboring national parks, Sequoia and Yosemite. The overall decline in national park visitation in the late 1990s hit Kings Canyon considerably harder than the other parks; from 1970 to 1990 it averaged almost a million visitors per year, but in the 21st century, it has averaged just 560,000. In 2016, it saw an increase to 607,479 visitors, which (with the exception of 2009) was the highest count since 1995. Since records began in 1904, an approximate total of 53 million people have visited Kings Canyon.

Campgrounds and hiking

In Grant Grove, the three major campgrounds are Azalea, Crystal Springs and Sunset, with 319 sites in total. With the exception of Sunset, they operate on a first-come, first-served basis. Cedar Grove has 314 sites in the Sentinel, Sheep Creek and Moraine Campgrounds, which are also first-come, first-served; sites at the Canyon View group camp must be reserved. During high demand periods, additional campsites may be placed on a reservation system. All campgrounds have flush toilets and showers, although water use may be restricted depending on the season.

There are a number of day hikes in the parts of Kings Canyon National Park accessible by road. In the Grant Grove area a one-mile (1.6 km) trail leads to the General Grant Tree, and several longer trails reach nearby points of interest such as Redwood Mountain, the largest sequoia grove. In Cedar Grove, easy hikes include the boardwalk path through Zumwalt Meadow – providing broad views of Kings Canyon – and the short walk to Roaring River Falls; there are also many longer day hikes such as an 8-mile (13 km) round trip to Mist Falls, and the 13-mile (21 km) round trip climb to Lookout Peak above Kings Canyon.

A number of historical sites in the park are easily accessible via short walks, including Gamlin Cabin, built c. 1872 by the Gamlin brothers, who had a timber claim at Grant Grove before it became a national park. it is believed to be the first permanent structure built in the park area. Knapp Cabin, listed on the National Register of Historic Places, is the oldest surviving structure in Cedar Grove, dating back to 1925. Another point of interest is the extensive Boyden Cavern system whose entrance is located just outside the park's western boundary, in the Monarch Wilderness. The cave was temporarily closed from 2015 until 2019 due to damage from the Rough Fire.

Backcountry travel

Since most of Kings Canyon is wilderness and roads extend only a small distance into the park, backpacking (and less commonly, horsepacking) are the only way to see the majority of the park. Unlike day hikers, overnight backpackers must obtain a wilderness permit from a ranger station or visitor center. During the peak tourist season (typically between May and September), a quota applies for wilderness permits, of which 75 percent are set aside for prior reservations, with the remainder for walk-ins. Outside the quota period permits are still required, although the limit no longer applies. Although backpackers account for a relatively small percentage of the total visitors, some of the backcountry trails are still quite heavily used. Due to the popularity of some backcountry camps, stays can be limited to one or two nights. During the summer, the Park Service staffs backcountry ranger stations at McClure Meadow, Le Conte Meadow, Rae Lakes, Charlotte Lake and Roaring River.

Road's End at Cedar Grove is a major jumping-off point for trips into the backcountry. The Rae Lakes Loop, 41.4 miles (66.6 km), is one of the most popular backpacking trips and passes through the deep canyons of Paradise Valley, the high Woods Creek suspension bridge and exposed alpine country before reaching Rae Lakes, a chain of glacial tarns set below 13,000-foot (4,000 m) peaks. Rae Lakes Loop hikers also climb over Glen Pass reaching a peak elevation of just under 12,000 feet. From the top of the pass, hikers can see views of Rae Lakes and the surrounding basin. The combined Pacific Crest Trail/John Muir Trail forms the backbone of the trail system, winding about 77 miles (124 km) from Piute Canyon at the park's northern tip to Forester Pass, 13,153 ft (4,009 m), in the south. Many hikes in Kings Canyon, including Rae Lakes, include parts of the PCT/JMT. There are also trailheads at Grant Grove which lead to more moderate hikes in the lower western Sierra Nevada, many in the Jennie Lakes Wilderness (just outside the national park).

Many parts of the park, such as the Middle Fork of the Kings River, are more difficult to access, requiring multi-day hikes over difficult terrain. Simpson Meadow on the Middle Fork is a 23-mile (37 km), one-way hike from Cedar Grove, with well over 12,000 feet (3,700 m) of elevation change. Other trailheads outside the park provide access to some of its more isolated locations, such as Tehipite Valley, a 14-mile (23 km) one-way hike from the Wishon Dam trailhead in the Sierra National Forest. The 3,000-foot (910 m) exposed and unmaintained descent into the valley is "notorious" as one of the park's most difficult hikes. Several trails also access the park from the Owens Valley to the east; all surmount passes more than 11,000 feet (3,400 m) high. The closest and most heavily used eastern approach is via Onion Valley Road, which terminates about a mile (1.6 km) east of the park boundary in the Inyo National Forest. The Kearsarge Pass Trail begins at Onion Valley Campground and links to the PCT/JMT via the eponymous pass.

During the spring and early summer, river crossings can be hazardous; in response the Park Service has installed bridges along some of the major trails. By late August or September of most years, rivers will have dropped to relatively safe levels. The high country is typically snow free between May and November, although in particularly wet years, large areas of snow may persist into July. In winter, cross-country skiing and snowshoeing are common activities. The Park Service provides ranger-led snowshoe walks and maintains some groomed trails in the Grant Grove area. Longer trips into the backcountry are also possible, although due to the rough terrain, typically deep snows and lack of ranger patrols during the winter, this is recommended only for skilled winter travelers. As with backpacking, wilderness permits are required for any overnight trips in winter.

Climbing and canyoneering

The large, exposed granite cliffs and domes in Kings Canyon provide opportunities for rock climbing. However, many such features require long or circuitous hikes to reach their bases, which deters many climbers. These include The Obelisk, overlooking Kings Canyon at the park's western boundary, multipitch climbs at Charlito Dome and Charlotte Dome well up the Bubbs Creek Trail, and Tehipite Dome, which requires a nearly 30-mile (48 km) roundtrip hike just to access. Many of the park's prominent peaks also require technical climbing – including North Palisade, the highest point in the park, and some of its neighbors along the Sierra crest. In The High Sierra: Peaks, Passes, Trails (2009) North Palisade is described as "the classic peak of the High Sierra ... It is striking from a distance and has routes that will challenge climbers of all abilities and preferences."

Canyoneering, bouldering, bushwhacking and rappelling are often necessary to explore parts of the backcountry without developed trails. A notably challenging route is down Enchanted Gorge in the Middle Fork backcountry, where Disappearing Creek vanishes under huge talus piles only to re-emerge several miles downstream, hence the name. Nearby Goddard Canyon is an easier – albeit still rugged – route, and is known for its scenic meadows and many waterfalls. The Gorge of Despair above Tehipite Valley is known for its combination of cliffs, waterfalls and deep pools, whose 3,000-foot (910 m) descent requires rappelling gear and wetsuits to achieve. Because of the park's size, lack of cell reception and limited personnel for search and rescue operations, only experienced cross-country travelers should attempt to hike off trail.

Water sports

In Cedar Grove, about 10 miles (16 km) of the South Fork are considered good waters for fly fishing. Although the river was once stocked with trout, the Park Service has not stocked the river since the 1970s, in favor of letting the fishery return to natural conditions. While rainbow, brown, and brook trout are found in various stretches of the river, only rainbows are native to the Sierra Nevada, the others having been planted by sportsmen in the early 20th century. The river is generally low and warm enough for wading by early autumn. In order to preserve the natural fishery, only catch and release is allowed for rainbows. A California state fishing license is required for visitors 16 years or older. The rainbow trout in the Kings river are small, usually no more than 8 to 9 inches (20 to 23 cm).

In order to protect riparian habitat, the gently flowing South Fork is closed to boating in Cedar Grove between Bubbs Creek and the western boundary of the park. However, swimming is allowed in certain sections of the river, with Muir Rock and the Red Bridge being popular swimming holes. Although there are many alpine lakes in the park at high elevations, most are impractical to access for boating or swimming. Nearby Hume Lake, formed by a historic mill-pond dam, is located in the Sequoia National Forest between the two sections of the park and is used for boating, swimming and fishing.

Most of the park's other rivers are extremely steep and fast-flowing, and are suitable only for advanced kayaking. The Kings River above Pine Flat Reservoir is a commercial whitewater run with its put-in near the western boundary of the park, but most of the run itself is on national forest. Most rivers in the park itself are inaccessible by road. The Middle Fork is one of the most difficult-to-access whitewater runs in the entire state, since boats and equipment must be carried through miles of backcountry to reach it. Canoe Kayak magazine describes the Middle Fork run, which passes through some of the most isolated parts of the Sierra, as "the very definition of epic with paddlers traveling around the world just to make a once-in-a-lifetime descent". Kayakers take about five days to descend the Class V Middle Fork from its 12,000-foot (3,700 m) headwaters to 900 feet (270 m) at Pine Flat Reservoir.
