In this small town in Valbella there are numerous prayer houses and buildings influenced by the Walser. You will also find the church of S. Bernardo. There are several very curious colored constructions.

The Piz de Ganan (2412 m) is recognizable by two large stone cairns. The side overlooking Lake Calvaresc is lush, while on the other side you find yourself faced with a severe Alpine landscape of rocks and debris. From Lake Calvaresc to Piz de Ganan the path becomes a challenging alpine route, where you don't have to suffer from vertigo and don't be afraid of the void.
