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.

Geo snowshoe hiking tour

Experience the tectonic arena of Sardona with snowshoes and a trained hiking guide. 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.

Visitor Pavilion World Heritage Sardona

Travel back in time to the origins of the UNESCO World Heritage Tectonic Arena Sardona. Along the line visible from far away, the Glarus main thrust, also known as the "magic line", 250-300 million year old rocks were pushed onto much younger ones, some of them "only" 35-50 million year old. This happened 10-20 million years ago far below the earth's surface!
In the visitors' pavilion at the Segneshütte you will get a unique insight into the history of the origin of the alpine mountains and the biggest landslide in the Alps. Immerse yourself in the past and travel back to the origins of the geological highlights of our region. Every Sunday, an expert GeoGuide conveys the modern view of the origins of the Alps.
