Geography

edit

The lake lies at an altitude of 1,797 metres above sea level, between Maloja Pass and Lake Silvaplana. Several mountains over 3,000 metres overlook the lake, notably Piz Corvatsch, Piz Grevasalvas and Piz da la Margna. The lake's drainage basin culminates at Piz Fora (3,336 m) and comprises the Vadrec da Fedoz glacier.

With a surface area of 4.1 km2, Lake Sils is the largest lake of the Engadine. It is also the largest natural lake in the Alps lying above 1,000 metres.[1] The lake was formed by a prehistoric landslide dam, similarly to Lake Silvaplana.[2]

The wooded Chastè peninsula extends into the lake at its north-eastern end. At the end of the peninsula there is a plaque to Friedrich Nietzsche with a passage from Thus Spoke Zarathustra. Near the peninsula is located the wooded island of Chaviolas, the largest in Lake Sils. Annually, in winter, the cross-country Engadin Skimarathon crosses the lake, starting at its edge in the Maloja Palace.

Boat connections run from end of June to end of September, making Lake Sils one of the highest lake in Europe with public transport boat route.[3]

The largest villages on Lake Sils are Sils im Engadin and Maloja (part of Bregaglia), located respectively at the eastern and western ends of the lake. Other hamlets are Cadlägh, Isola and Plaun da Lej.
