Piz Giuv, Mountain peak in Glarus Alps, Switzerland

Piz Giuv is a mountain summit in the Glarus Alps standing at 3,096 meters and positioned between three valleys: Fellital, Etzlital to the north, and Val Giuv to the south. The peak sits where these valleys meet, making it a natural landmark in the region.

The name Giuv comes from Romansh for "yoke" or "pass"; German speakers also call the mountain Schattig Wichel. The border between Uri and Graubünden runs across the 3,096 m summit, which rises between the Fellital and Etzlital to the north and the Val Giuv to the south. The slightly lower Piz Nair (3,059 m) stands directly to its east.

The mountain is known locally by two names, Piz Giuv and Schattig Wichel, reflecting how the border region between Uri and Graubünden blends different language traditions. Visitors may encounter both names in local conversations and on maps.

The Etzlihütte (SAC) at 2,052 m serves as the base, reached from Bristen in the Maderanertal to the north or from the south via Mittelplatten or the Chrüzlipass, accessible from Sedrun or with lift help from Disentis. In summer the route from the hut is a high-alpine climb with rock, partly very brittle, and ice passages. In late winter Piz Giuv is a ski touring summit, and the mountain can also be climbed directly from the Oberalppass as a day tour.

The mountain and its surroundings have drawn local crystal hunters, known as Strahler, for about 200 years. They search Val Giuv and neighbouring valleys for smoky quartz, milarite, adularia, titanite, epidote, calcite, amethyst, apatite and pyrite; Val Giuv smoky quartz is among the most sought after worldwide. A paid permit from the municipality is required to search.
