Sardona-Welterbe-Weg, Stage 5/6

Piz Sardona is circumnavigated via steep grassy slopes and a rocky ridge. Clear mountain lakes, beautiful river courses embedded in the rock and mighty waterfalls are reminders of the forces of nature that created the geological phenomena in this area. Marmots, ibexes and even bearded vultures can be sighted here.

This roughly seven-hour mountain hike begins at the Sardonahütte at around 2'160 m, at the far end of the Calfeisental. The starting point is not served by public transport; the nearest stop, Cassons, is around 4.4 km away. From the hut, the white-red-white marked mountain trail climbs through open, increasingly rocky terrain.

After about five kilometres, the route reaches its highest point at around 2'470 m near the Fahnenstock. Shortly afterwards, it crosses the Heubützlipass, a mule track on the ridge between Fahnenstock and Heubützler. A long descent into the Foo area follows before the trail climbs once more to the Foopass at around 2'220 m. The pass links Weisstannen with Elm and also marks the cantonal border between St. Gallen and Glarus.

Beyond the Foopass, the route initially remains in open terrain. Later, the trail broadens and enters the Wisliwald, where a barbecue site lies close to the route. The final descent leads through the forest and past the first houses to Elm. After around 20 kilometres, the hike ends just a few steps from the Elm, Station stop.
