Foo Pass

The Foo Pass (Foopass) is a mountain pass of the Glarus Alps, located on the border between the Swiss cantons of St. Gallen and Glarus, at an elevation of 2223 m. It crosses the col between the peaks of Foostock and Piz Sardona.

The pass is traversed by a trail, which connects the village of Weisstannen, in the canton of St. Gallen at an elevation of 1004 m, with the village of Elm, in the canton of Glarus at an elevation of 977 m. The trail forms part of the Alpine Pass Route, a long-distance hiking trail across Switzerland between Sargans and Montreux.

The alpine pasture below the pass on the St Gallen side is notable for its marmot colony.
