The lake's drainage basin culminates at Piz Fora (3,336 m) and comprises the Vadrec da Fedoz glacier.

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.
