Through Archipelago

Sark has a population of about 500. Most of Sark’s residents live in The Village, its main settlement and administrative center. Including the nearby island of Brecqhou, it has an area of 2.10 square miles (5.44 km2). Little Sark is a peninsula joined by a natural but high and very narrow isthmus to the rest of Sark Island.

Sark is one of the few places in the world where cars are banned from roads, and only tractors, bicycles, and horse-drawn vehicles are allowed. In 2011, Sark was designated as a Dark Sky Community and the first Dark Sky Island in the world.

Geography and geology

Sark consists of two main parts, Greater Sark, located at about 49°25′N 2°22′W / 49.417°N 2.367°W, and Little Sark to the south. They are connected by a narrow isthmus called La Coupée which is 300 feet (91 m) long and has a drop of 330 feet (100 m) on each side. Protective railings were added in 1900; before then, children would crawl across on their hands and knees to avoid being blown over the edge. A narrow concrete road covering the entirety of the isthmus was built in 1945 by German prisoners of war under the direction of the Royal Engineers. Due to its isolation, the inhabitants of Little Sark had their distinct form of Sercquiais, the native Norman dialect of the island.

The highest point on Sark is 374 feet (114 m) above sea level. A windmill, dated 1571, is found there, the sails of which were removed during World War II. This high point is named Le Moulin, after the windmill. The location is also the highest point in the Bailiwick of Guernsey. Little Sark had a number of mines accessing a source of galena. At Port Gorey, the ruins of silver mines may be seen. Off the south end of Little Sark are the Venus Pool and the Adonis Pool, both natural swimming pools whose waters are refreshed at high tide.

The whole island is extensively penetrated at sea level by natural cave formations that provide unique habitats for many marine creatures, notably sea anemones, some of which are only safely accessible at low tide.

Sark is made up mainly of amphibolite and granite gneiss rocks, intruded by igneous magma sheets called quartz diorite. Recent (1990–2000) geological studies and rock age-dating by geologists from Oxford Brookes University shows that the gneisses probably formed around 620–600 million years ago during the Late Pre-Cambrian Age Cadomian Orogeny. The quartz diorite sheets were intruded during this Cadomian deformation and metamorphic event.

All the Sark rocks (and those of the nearby Channel Islands of Guernsey and Alderney) formed during geological activity in the continental crust above an ancient subduction zone. This geological setting would have been analogous to the modern-day subduction zone of the Pacific Ocean plate colliding and subducting beneath the North and South American continental plate.

Sark also exercises jurisdiction over the island of Brecqhou, only a few hundred feet west of Greater Sark. It is a private island, but it has recently been opened to some visitors. From 1993 Brecqhou was owned by the brothers David and Frederick Barclay, until David Barclay died in 2021 and Frederick Barclay became sole owner. The brothers contested Sark's control over the island. The candidates endorsed by their various business interests on the island failed to win many seats in the elections held in 2008 and 2010.
