The earth's history within reach

UNESCO Sardona

Forget the Himalayas, Rockies and Andes – if you really want to know how mountains form, take a trip or hike up the mountain in Flims and witness geological processes at work like nowhere else in the world.

The natural phenomenon

The district’s geological features, including the aftermath of one of the world’s largest-ever rockslides,
have even earned it UNESCO World Heritage Site status. In 2008, a 300-square-kilometre section of this illustrious area, stretching across the cantons of Graubünden, St. Gallen and Glarus, was named the Sardona tectonic arena and incorporated into the larger Sardona geopark.

Eine kilometerlange, messerscharfe Linie trennt unübersehbar zwei verschiedene, aufeinanderliegende Gesteinsarten. Entgegen der geologischen Normalität ruhen hier 250 bis 300 Millionen Jahre alte Gesteinsschichten auf wesentlich jüngeren, die es gerade mal auf 35 bis 50 Millionen Jahre bringen. Die Überschiebung bzw. die auch «magisch» genannte Linie ist an mehreren Stellen gut zu sehen, so unter anderem in Flims vom Ringelspitz bis zu den Tschingelhörnern. Dort befindet sich mit dem Martinsloch noch ein weiteres Naturphänomen.

Visitors’ pavilion

A classroom of monster proportions: learn about the Sardona tectonic arena at a new visitors’ pavilion at the Segneshütte – or just by looking all around you.


Engaging learning

For the Sardona tectonic arena, being part of a UNESCO World Heritage Site brings with it a number of responsibilities, for example, it is obliged to communicate the area’s unusual landscape features to the general public. Consequently, visitors to Flims have access to various facilities to help them learn about
the site. In the past, the Cassonsgrat mountain afforded good views of the Sardona World Heritage Site and was the starting points for tours led by official GeoGuides. However, at the end of 2015, the cable car up the Flimserstein became too old to maintain and had to be shut down. It is likely to be some time before a new cable car is available for travelling to the Sardona tectonic arena. But in the meantime, a new pavilion has been built close to the Segneshütte to provide visitors with information and orientation.

Here, they can discover in depth the secrets of the surrounding landscape with the help of imaginative digital animations. The pavilion also affords unique views of the World Heritage Site, the site of the Flims
rockslide and the Rhine gorge. There is also another new, engaging way of experiencing the tectonic arena: the UNESCO Sardona mobile app, which will be available in July. This augmented-reality app takes users on a thrilling voyage of discovery and lets them view the region in totally new ways using their smartphone. The visitors’ pavilion is open from 2 July to 23 October 2016 and can be reached via the
chairlift from Naraus, the Grauberg cable car from Startgels, or the Nagens Shuttle from the cable cars in Laax. The bus now runs on all seven days of the week.
