Do you want to understand how the Alps were formed? You can get to the bottom of this question in the Sardona Tectonic Arena. Here, ancient rock pushed over younger rock - and created a habitat full of diversity. You can still see the traces of these powerful forces today: at Martinsloch, at the Tschingelhörner or in the surrounding mountains.
On the Segnesböden you will find protected nature of national importance. But all around - on the Flimserstein, the Cassonsgrat or in the Bargis high valley - a special biodiversity awaits you. To preserve it, you need to be mindful of nature, its plants and animals.
In the Sardona visitor pavilion at the Segneshütte, you can gain a unique insight into the history of the formation of the Alpine mountains and the largest landslide in the Alps. Immerse yourself in the past and travel back to the origins of the geological highlights of our region. The pavilion is open daily and every weekend an expert GeoGuide provides a modern view of the formation of the Alps.

Explore the colorful alpine flora on the Sardona Mountain Flower Trail. Your trail starts at the Segnes mountain station. Over 40 panels tell you exciting facts about the alpine plants and show you how diverse and fascinating their habitat is.
Be careful, you are walking in the Flimserstein plant conservation area. Don't pick any flowers and stay on the path - this way you help to preserve nature.
The first part of the trail (between the Segneshütte and Alp Nagens) is always accessible - the second section will open in summer 2025 and will add further highlights to the nature experience.
In order to preserve the special nature on the Segnesboden, we ask you to observe the following rules of conduct:
The Tectonic Arena Sardona provides unique insights into the history of the formation of the Alpine mountains and valleys. Along the line visible from afar, the Glarus Thrust, also known as the “magic line”, 250-300 million year old rocks were pushed onto much younger rocks, some of which are “only” 35-50 million years old. This happened 10-20 million years ago, far below the surface of the earth at that time!

A wild mountain stream, a fairy-tale forest, several bridges and a breathtaking mountain panorama in the heart of the UNESCO-World Heritage Site Sardona. Trutg dil Flem leads you along the Flem stream from the Segnesboden, passing through the site of the largest landslide in European history, before returning to Flims. From the lower Segnesboden, you can enjoy wonderful views of the Tschingelhörner. On the descent back to the town, you will cross seven bridges, some of them based on audacious designs, before returning to the Flims fairy-tale forest.
The first almost 500 meters of altitude up to Tschinglen-Alpkann can be overcome with the Tschinglen cable car. There are also refreshment and overnight accommodation facilities here. This is followed by the steep ascent to Brünschegg, from where the summit jags of the Tschingelhörner are very clearly visible above the razor-sharp line of the Glarus main overthrust. Arriving at the Segnespass, you have a magnificent mountain panorama. The steep descent follows over the lower Segnesebene to the Segneshütte, from where the Flimserstein becomes visible. Via the Trutg dil Flem you descend to Flims, the destination or starting point of the Sardona World Heritage Trail.
Looking to try out the fascinating world of climbing sports for the first time? This high mountain valley situated at 2,100 metres above sea level with 31 climbing routes is the perfect place for novices and families to make their first attempts. The rocks on the Segnesboden are strong limestone rock, perfect for climbing. In preparation, take note that the walls of the Segnesboden climbing garden may still contain traces of snow at the beginning of summer due to its high altitude and location.
