UNESCO World Heritage Site Sardona

A unique glimpse into the formation of the Alps

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 download the Sardona app.

Tschingel-Hörner & Martinsloch

One of the best places to see the effects of the Glarus thrust are the nine peaks of the Tschingelhörner. The jagged peaks edges are unique and impossible to miss. However, twice a year, the Martinsloch opening below steals the show. For a few minutes in March and October, the sun shines through the 22-metre high, 19-metre wide, window in the rocks onto the church steeple in Elm. This is a unique experience and always attracts many visitors to the area.

Glarus thurst

Here, mountains are king. The geological fact that older rock lies on top of younger rock sounds false to our ears. Yet this is exactly the case here. When two tectonic plates from Africa and Europe collided, the older layer of rock was pushed above the younger one. The original layers of rock were pushed onto one another, folded over and ultimately broken into pieces. The consequences of this enormous force are clearly visible from the Martinsloch opening on the Tschingelhörner.

Segnesboden

Even if you are a regular visitor to the upper and lower Segnesboden, you will experience something different each time. The streams on the two elevated plains are constantly changing their course, so the moor, which makes up around half of the alluvial soil, keeps forming new patterns, with new lakes continually forming and disappearing. In 1996, this cauldron-shaped alluvial plain, known as Plaun Segnas Sut or the lower Segnesboden, was recognised as a landmark of particular beauty and importance in the Federal Inventory of Alluvial Zones.

Suggested hikes

Trutg dil Flem, upper part

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.

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.
