The Lemaire Channel runs from False Cape Renard to the north through to Cape Cloos down in the south. It is one of Antarctica’s top attractions. The most spectacular stretch is located between the mainland Antarctic Peninsular and Booth Island. The strait is 11 km long and 1,600 metres wide at its narrowest point. It was first discovered by a German expedition in 1873-74, but it was a Belgian expedition in 1898 that first traversed it. It is named after the Belgian Congo explorer Charles Lemaire.
Its steep cliffs and iceberg-filled passage give it a beauty that has earned it the nickname of Kodak Gap. Its protected waters are as still as a lake, making it ideal for cruising. Visitors should be warned that the passage can become blocked by icebergs in the early part of the season. At the northern end of Lemaire Channel are two snow-capped twin peaks known as Una’s Tits which are also a popular photo opportunity for tourists.
