I highly recommend Route 304! The scenery is stunning, and if you ride up from the Klöntal Valley, you can ride anywhere on an e-bike. On the descent from the Längenegg Pass toward Obersee, I had to push my bike a few times. Going in the opposite direction, you'll probably have to push up about 100 meters in elevation.

Next time I would do the tour in the opposite direction because trails go down from Obersee.

Escaped the heat in the valley and found the heat on the mountain 🥵. Längenegg is always challenging. Nice round with Ludi who took all the photos.

With Ludi and Föhn wind 🌬 across Längenegg. Possibly the last time in 2025.
Wonderful 🍁🍂 atmosphere along the two lakes.

Great tour in the Glarner mountains. From Näfels up to Oberseeli (all paved roads), from there on a gravel path along the lake and then on to Lachenalp (first paved side road, then forest road). After the Schwiibodä comes the Obere Lachenalp. From there you have to push the last 100hm to the summit. Departure to Klöntalersee on a forest …

The descent to Oberlachen was quite muddy. I met a few bikers on the ascent there. Summer temperatures and a wonderful display of flowers.

From Netstal to the Klöntalersee. Along the lake towards Langenegg. The climb was tough (at least for me) even with an eMTB, but the view from the pass makes up for it. The descent requires a lot of pushing at the beginning, but after that it is very beautiful and at the end you are rewarded with the wonderful Obersee. …

Got through without rain, quite fresh on the Längenegg and still quite a bit of snow on the north side, but it is easy to walk/drive on.

Frequently Asked Questions

Where can I park and start the Längenegg Bike route?

The Längenegg Bike route typically starts and ends in Näfels. You can find parking options there to begin your tour.

What is the terrain like on this mountain bike trail?

The terrain is varied and challenging. It starts with a steady climb through a forest, then transitions to a paved road near Obersee (Glarus). As you ascend towards Sulz, it becomes more demanding with bumpy sections over roots and stones. A significant portion, especially from Ober Lachenalp to Längenegg Pass, requires pushing or carrying your bike due to its steep and rough nature. The descent features partly loamy ground, widening into a natural trail with grassy, fast-riding sections.

Is the Längenegg Bike trail suitable for beginners or families?

No, this trail is categorized as difficult and requires good to very good fitness and advanced riding skills. The demanding climbs and technical descents, including sections where you need to push or carry your bike, make it unsuitable for beginners or families with young children.

What are the best times of year to ride this route?

The best time to ride the Längenegg Bike route is generally during the warmer months when the alpine passes are clear of snow, typically from late spring to early autumn. Always check local conditions before you go, as weather can change rapidly in the mountains.

Are dogs allowed on the Längenegg Bike trail?

While dogs are generally allowed on trails in Switzerland, it's important to keep them on a leash, especially in alpine areas with grazing livestock and wildlife. Given the trail's difficulty and technical sections, consider if it's suitable for your dog's fitness and paw health.

Are there any permits or entrance fees required for this trail or the surrounding area?

There are no specific permits or entrance fees required to ride the Längenegg Bike trail itself. However, parts of the route traverse the Auengebiet Hinter Klöntal, a protected wetland area. Always respect local regulations, stay on marked paths, and practice Leave No Trace principles to preserve the natural environment.

What kind of views and landmarks can I expect along the way?

You'll be treated to breathtaking alpine scenery. Highlights include the serene Obersee (Glarus), the remote Obersee Alp, and the panoramic Längenegg Pass. From the highest points, you'll get expansive views of peaks like Redertenstock, Muttristock, Lachenstock, Zindlenspitz, and the impressive rock faces of Glärnisch and Vrenelisgärtli mountains. Don't miss the View of Lake Klöntal from Schwändeli.

Does the Längenegg Bike trail intersect with other well-known paths?

Yes, while primarily following the Längenegg Bike route (98%), sections of this tour also briefly intersect with other paths such as the Suworow-Route, Pragelpass-Weg, Seerundweg Klöntal, and the Alpine Panorama Route.

Are there any places to eat or stay near the route?

While the trail itself traverses remote alpine landscapes, you'll find some huts like Obersee Alp, Am Sulz, 1,316 m, and Lachenalp 1563 (Stäfeli) which might offer refreshments or basic accommodation. For more extensive options like cafes, restaurants, and hotels, you would need to look in nearby towns such as Näfels or around Lake Klöntal.

What should I be aware of regarding the difficulty of the Längenegg Bike route?

Be prepared for a significant physical and technical challenge. A key point to note is the section from Ober Lachenalp to Längenegg Pass, where you will likely need to push or even carry your bike for about 30 minutes due to the extremely rough and steep path. This is a defining characteristic of the route and requires strong stamina and technical skill.

How long does it typically take to complete the Längenegg Bike route?

The route is approximately 38.5 km (23.9 miles) long and typically takes around 4 hours to 4 hours and 30 minutes of riding time to complete. However, this can vary significantly based on your fitness level, technical skill, and how often you stop to enjoy the views.
