Discover how the mountains and valleys of the Alps were formed. 

The Tectonic Arena Sardona UNESCO World Heritage Site provides unique insights into how the mountains and valleys of the Alps were formed. Nowhere else in the world are the peaks which tell the story of the formation of mountains so monumental and so eye-catching as on the borders between the cantons of Glarus, Grisons and St. Gallen. Discover the region together with an expert GeoGuide or on your own – by embarking on a challenging multi-day tour through the mountainous landscape, going on a day trip to one of the many themed trails or visiting a geological site.
