Swiss Tectonic Arena Sardona

Mid August we visited the Sardona region for a couple of days. As mentioned in the description, the area is most famous for the ‘Glarus thrust’ whereby older mountains are located on top of younger mountains because of movement of the earth's crust. Below some practical points with respect to the three hikes we did in and around the core zone.

Elm: from the small village of Elm, the Tschinglenbahn cable car goes to the Tschinglenalp where a relatively short and easy hike to the Firstboden viewpoint starts. Starting the hike from the lower end of the cable car is also possible. From the Firstboden viewpoint there is an excellent view on the Glarus thrust and the Martinsloch (cf. picture). A small parking is available at the cable car station and also one a couple of hundred meters down the road. The fee for the cable car is CHF 18 (return ride) and on the Tschinglenalp there is a place to eat and drink (Tschinglen Wirtschaft).

Wangs: the 5 lakes hike starts in Wangs with a cable car to Furt, a chairlift from Furt to Gaffia and another chairlift from Gaffia to Pizolhütte at 2.222 meters. The hike ends at the Gaffia chairlift so the way down is somewhat shorter. A combined return ticket will set you back CHF 98 (plus CHF 5 for the (large) parking). The hike is a good 11 kilometers with three steeper sections, a total ascent of approx. 600 metres. The total decrease …

I mainly want to give an update about the accessability of the WHS area. In Flims, the old cable cars are replaced by a new system called "Flims Express", which will serve the Foppa-Naraus-Fil de Cassons line. However, the new lift is not expected to be operational before the end of 2024, and the old cable cars are already out of service. This means that the cable car tour described in some of the other reviews is no longer available. You can still hike the Foppa-Fil de Cassons route, but this means hiking all the way up from Flims and down again. To at least get a a good view of the main "arena" area with the Tschingelhörner, I opted for the alternative route from Flims, which is going up by the second main cable car line "ArenaExpress" up to Nagens. The WHS area can't be seen from there, but there is a rather short (30min) hiking trail over the mountain hump to the end station of the "Grauberg" lift (which was also not running). From there, you have a pretty good view over the main arena area (see the picture). However, you are technically still only at the border of the core zone. To be sure, you have to go down the hiking trail to the "Untere Segnesboden", the lower plain below the Segnes pass. Although it was a nice sunny September day, the whole area was already covered in ice and snow. Considering my flimsy shoes and equipment, …

In what was dubbed by some a mini meetup me and Philipp ventured into the Sardona Tectonic Area. It was a mostly sunny July day when we set out from Flims to cross the mountain range at the Pass dil Segnas and descent on the other side to Elm.

It all started with a bit of a misunderstanding. Philipp had send me a trail map of the 6th day of the world heritage trail. I took it to mean he wanted to do the full trail when his original intention was to do only a part of it. He didn't see the need to correct me on my misunderstanding. Or put in any effort to clarify what the Swiss mean when they categorize a trail as hard. So we did the full trail.

We met in Chur in the morning and took the bus to Flims. In Flims you can start the trail or catch a lift up into the mountains. There are multiple stops on different alitutde levels. We decided to go up to the first stop, Focca, from where we started our 8h, 19km, 1500m altitude difference (up and down) hike.

On the Flims side it's a fairly steady climb on good trails in a beautiful landscape. For parts of it we followed a mountain river. When we reached the upper plateau at Camona de Segnas it started to rain. Philipp hadn't bothered to bring a rain coat. And I noticed that I …

I visited this WHS in June 2014. I based myself in Flims and already getting there by car made my trip worthwhile. About 100m from the tourist information centre, I bought my tickets to the Fil de Cassons. From Flims I went up to Foppa (1420m) by chairlift, up to Naraus (1843m) again by chairlift, and up to Cassonsgrat (2695m) by cable car. The return trip cost around 35 euros. At every stop there are information boards, a bar or restaurant, a panoramic viewpoint and toilets. I suggest taking your time to acclimitise at each stop to avoid any possible altitude sickness. The temperature difference from Flims to Cassons was around 18 degrees so wear layers and bring a good windjacket and good hiking boots. Once I arrived at Cassonsgrat, I hiked at the panoramic viewpoint with the UNESCO information boards and a clear view of the Tschingelhörner. From there I ventured on a strenuous hike on a trail called "Fuorcla Raschaglius" (30 minutes) and another trail called "Pass dil Segnas" (2.5hours). Although I visited in late June, it was quite cold and there was quite a lot of snow left. After spotting several marmots and alpine birds and flora, I found my way back to Cassons and down to Flims.

For my visit, I chose the approach from the south side. Two chairlifts and a cable car ride from the town of Flims brought me up on the Fil de Cassons, at the altitude of 2634m. This mountain ridge itself is part of the core zone of the WHS. The best thing however is the view of the surrounding mountains: no less than 555 Alpine peaks can be seen from here on a clear day. And although IUCN did not value the scenery as exceptionally beautiful, I found the 360-degree view pretty spectacular.

There's an easy hike at the ridge of the Cassons with displays to tell you all about the geology, flora and fauna. In preparation, I had tried to read the nomination file for this WHS, but it seems to have been drafted specifically for geology experts. It includes so many specific words that I did not really get a clue what it all is about. The only element that I can reproduce is that older rocks occur here on top of younger rocks, an effect created by the movement of the earth's crust. The different effects this has on the layout of the mountains can indeed be easily seen from here.

The area also is the starting point for several hikes. From Cassons I walked down to the lowest cable car station in Naraus. The path descends very steeply all the way. It is narrow, and loose stones and muddy stretches keep you on alert …

I visited the Sardona range from two sides. From the north by the bergbahn from Flims, accessed by postbus from Chur. The next day I approached from the south, by cable car from Elm, accessed by Postbus from Schwanden.

More of the tectonic area is visible from the south side.

The most impressive mountains of the Swiss Tectonic Arena Sardona are the Tschingelhörner. To go there I suggest you travel to Elm, a small picturesque village in the Glarus region. The village is easily reached by car. Otherwise take a bus from Glarus (the city) as there is no train. In Elm you will find a small funicular that brings you close to the mountains. To get a closer look the only way is to hike. There are (quiet expensive) 1 to 2 days guided tours on weekends that bring you close to the Tschingelhörner. To see the whole area you can hike from Elm to Flims. The trip takes about 6.5 hours and shouldn't be done by inexperienced mountain hikers.
