It is a satellite peak of Piz Bernina, joining it by its north-east ridge via a 3,882 m pass.

The mountain has a prominent secondary summit called the Schneehaube (3,875 m).

The first ascent of Piz Scerscen was by Paul Güssfeldt, Hans Grass and Caspar Capat on 13 September 1877 via the north-west spur, descending the same way.

This is the well-known Eisnase route, involving a 100-metre ice pitch of between 60 and 70°,[2] although its precise length and steepness are debated.

The first ascent of the north-west face was by Christian Klucker and L. Norman-Neruda on 9 July 1890.
