The most common starting point is the Tierfehd cable car station. From there, a dramatic and steep cable car ride takes you up about 1,000 meters in altitude, providing initial breathtaking views and significantly shortening the ascent to the trail. Alternatively, you can start directly from Linthal, though this makes the journey considerably longer and more strenuous.
No, this trail is generally considered difficult and is not suitable for beginners or young children. It demands good physical fitness, sure-footedness, sturdy hiking boots, and prior alpine experience. The terrain includes steep sections, narrow paths with some exposure, rocky stairs, and scree.
The ideal period for this hike is from mid-June to mid-October. During these months, the trails are typically clear of snow, making the route safer and more accessible.
While specific regulations for dogs are not detailed, alpine trails in Switzerland generally permit dogs on a leash. Given the challenging terrain and potential for wildlife sightings (like Chamois and Ibex), it's advisable to keep dogs under strict control. Always ensure your dog is capable of handling difficult alpine conditions.
There is no specific permit or entrance fee required to hike the trail itself. However, you will need to pay for the Tierfehd cable car if you choose to use it for access. The trail is located within the UNESCO World Heritage Tectonic Arena Sardona, so please respect all natural regulations and leave no trace.
This hike offers several unique features. You'll traverse a surreal 3-kilometer illuminated power station tunnel leading to the breathtaking turquoise-blue Muttsee Reservoir. The trail also provides expansive Panoramic View of Fisetengrat and Surroundings of the Glarus Alps. The destination, Muttsee, is home to Europe's highest artificial lake and an alpine solar power plant. You'll also hike along parts of the Chalchtrittli Trail.
Given the difficult nature of the trail, you should bring sturdy, ankle-supporting hiking boots, appropriate layers of clothing for alpine weather changes, rain gear, sufficient water and snacks, a first-aid kit, and a map or GPS device. Trekking poles can also be very helpful on steep and rocky sections.
Yes, sections of this route overlap with other official trails. You will encounter parts of the Via Glaralpina, as well as access tunnels like Zugangsstollen 2, Schutterstollen, and Sondierstollen, which are part of the hydroelectric infrastructure in the area.
Near the Muttsee, you'll find the Muttseehütte SAC, a Swiss Alpine Club hut. It serves as a welcoming stop for refreshments or an overnight stay, offering a true alpine experience. In Linthal, at the base of the valley, you can find more extensive amenities, including accommodation and dining options.
The terrain is rugged and varied, characteristic of high alpine environments. Expect steep ascents, narrow paths that can have some exposure (though typically at least one meter wide and often secured with chains), rocky stairs, and scree, particularly on descents. Good sure-footedness is essential.
To fully appreciate the unique engineering and natural beauty, consider taking the Tierfehd cable car up. This allows you to save significant energy for the main alpine hike and experience the dramatic ascent. For those seeking an even greater challenge, starting directly from Linthal offers a much longer and more strenuous journey, but rewards with a deeper immersion into the valley's landscape before reaching the high alpine.
In addition to the nearly 9 km circular route, you also have to add the 3 km return route through the service tunnel! So, in total, the circular route is about 12 km.
Hike in Glarus – via Chalchtrittli, Muttenchopf, Limmerensee, and the Schreyenbach Waterfall Today I headed to the beautiful Glarus region (GL), to Linthal and the Tierfehd. There, I was able to park easily and comfortably conquer the first few meters of elevation with the cable car – an ideal start. The actual climb began at Chalchtrittli: steep but impressive. Before reaching the Muttensee Hut, I made a detour to Muttenchopf – with a stunning view of Limmerensee and the surrounding mountains. The alpine flora was beautiful, the surrounding mountains formed an imposing basin, and I really enjoyed the hike. After the descent to Limmerensee, the return route led through the approximately three-kilometer-long access tunnel back to the cable car. It was cool, fresh, and quite adventurous in places – especially since I was almost alone. I briefly climbed out onto the dam wall before continuing back through the tunnel. Back at the parking lot, my day wasn't quite over yet: I made an additional detour to the Schreyenbach Falls – an impressive waterfall that only flows about 45 days a year. Otherwise, the water is probably diverted for power plant purposes. This short hike was about 3.5 km long, but wasn't recorded. An all-around successful day with plenty of variety, quiet moments, impressive mountain scenery – and a rare natural experience to round it off.
