UNESCO-World Heritage Tectonic Arena Sardona

Have you always wondered how the Alps were formed? Then you’ve come to the right place at the UNESCO-World Heritage Site Sardona. There is hardly any other place in the world where you can see how mountains are formed as well as in the region above Flims. For this reason, the Tectonic Arena Sardona was recognised as a World Heritage Site by UNESCO together with an area spanning 32,800 hectares in 2008. If you are interested in how the world looked when the Glarus thrust was still active, you should take a look around the visitor pavilion or join a snowshoe tour with a GeoGuide.

World Heritage Sardona Snowshoe Experience

Experience the Tectonic Arena Sardona with snowshoes and a professionally trained GeoGuide Sardona. You will see, understand and marvel at how the Alps were created on a wonderful snowshoe tour. The tour takes place on a signposted and secured snowshoe route.
