Piz Grevasalvas, Mountain summit in Grisons, Switzerland

Piz Grevasalvas is a 2,931 m summit in the Albula Alps, in the Swiss canton of Graubünden. It rises between the Julier Pass and Lake Sils, above the Lunghinsee, and its east side is flattened and easy to climb. The summit marks the municipal boundaries of Sils im Engadin/Segl, Bregaglia and Surses.

The summit lies on the municipal boundary between Sils im Engadin/Segl, Bregaglia and Surses, a tripoint fixed on the peak. Below it, the Lunghinsee at 2484 m is regarded as the source of the Inn, and the Pass Lunghin southwest of the peak joins the watersheds of the North Sea, Mediterranean and Black Sea. The summer settlement of Grevasalvas east of the mountain served as the set for the 1978 Heidi television series.

The name Grevasalvas combines the Romansh greva (fine scree) and alv (white, from Latin albus). East of the summit lies the summer settlement of Grevasalvas, where the 26-part children's series Heidi was filmed in 1978, closely following Johanna Spyri's novels.

You can start hiking from Plaun dal Lej or Maloja and follow marked trails that cross rocky mountain terrain on the way up. The route is walkable in fair conditions but expect elevation changes and bring appropriate footwear or climbing gear.

The mountain slopes have sparse vegetation that opens up unobstructed views of the Bernina Group and Lake Sils during the climb. This exposed landscape makes it easy to see across the range and surrounding lakes.
