Geography

Sark is a 45-minute boat journey east of Guernsey. It is almost two islands, the two parts being joined by a narrow isthmus known as La Coupée. The island is a plateau, with a collection of animals and plants unique to Sark. In the spring and autumn, the island becomes home to an unusual selection of migratory birds. The main village is situated at La Collinette. The coastline is rugged, with many cliffs and caves.

Herm lies between Guernsey and Sark. It has lush and varied scenery, with meadows, unusual wild flowers and steep cliffs overlooking secluded coves and pounding surf.
