The Gelmer Dam above Handegg is 35 meters high and 370 meters long. It dams the turquoise-colored Gelmersee at 1,850 meters, which is used to generate electricity. The steep Gelmerbahn cable car (up to 106% gradient) takes you spectacularly to the dam in just 12 minutes – from there, the circular hike around the lake begins (4.5 km / 2–3 hours / T2–T3). Surefootedness is required: narrow rocky paths, secured with ropes – not suitable for strollers. 🔹 Panoramic trail around the lake 🔹 Ascent to the Gelmerhütte SAC (2,412 meters) is possible

Hikes around Mattenalpsee are generally considered challenging, with many routes rated as difficult (T2, T3, and T4 tracks). They often require very good fitness, sure-footedness, sturdy shoes, and alpine experience due to steep, moderately exposed sections with loose rocks and rugged terrain.
While the region is known for its demanding trails, there are a few easier routes available. Out of the 51 trails, 7 are rated as easy and 11 as moderate, offering less strenuous options to experience the alpine environment.
Hikers can expect to see the stunning turquoise Mattenalpsee itself, fed by the fast-retreating Gauligletscher. Other notable features include the beautiful Gaulisee, impressive alpine lakes, glaciers, steep jagged mountains, and huge glacially-fed waterfalls on the opposite side of Mattenalpsee. The View of Gelmersee – View of Gelmersee loop from Gelmersee offers views of another prominent lake.
The remote and rugged nature of the Mattenalpsee trails means they can be challenging for dogs, especially with steep sections and loose rocks. While dogs are generally allowed on Swiss hiking trails, it's crucial to assess your dog's fitness and ensure they are accustomed to alpine conditions. Always keep dogs on a leash, especially near livestock or wildlife.
Yes, several circular routes are available. For instance, the View of Holzfadghirmi (1850 m) – Gauli Area loop from Glogghüs is a difficult 11.0 km loop, and the Holzhüüs Cabin – Gasthof Bären Guttannen loop from Guttannen is another difficult 11.5 km circular path.
The best time to hike around Mattenalpsee is typically during the summer months, from late June to early October, when the snow has melted and trails are more accessible. Early in the season, hikers may still encounter remnants of avalanches. Always check local weather and trail conditions before heading out, as alpine weather can change rapidly.
Access to Mattenalpsee is challenging as there are no cable cars or roads directly to the lake. Public transport options would likely involve reaching a nearby village like Guttannen, and then embarking on a long hike over rugged terrain to reach the Mattenalpsee area. Planning your journey in advance with local transport schedules is essential.
Given the remote nature of Mattenalpsee, direct parking at the lake is not available. Hikers typically park in nearby villages or designated starting points for the longer approach hikes. For example, routes like Holzhüüs Cabin – Gasthof Bären Guttannen loop from Guttannen start from Guttannen, where parking options may be found.
For those undertaking more demanding, multi-day hikes, the Gaulihütte serves as a recommended overnight stay. This allows hikers to break the journey into a two-day trek, providing a base in the remote wilderness.
The Mattenalpsee area is characterized by its remote and untouched wilderness, meaning there are very few, if any, commercial establishments directly on the trails. For places to eat or drink, you would typically need to return to nearby villages like Guttannen. The Gaulihütte offers basic provisions for overnight guests.
Hiking around Mattenalpsee offers a profound sense of tranquility and a chance to experience nature away from crowds. Its remoteness, combined with the dramatic backdrop of turquoise alpine lakes, retreating glaciers, and steep, jagged mountains, provides a truly immersive wilderness experience and peaceful solitude.
Mattenalpsee is a high-alpine lake fed by the Gauligletscher, meaning its waters are extremely cold, even in summer. While there are no official restrictions against swimming, the frigid temperatures make it suitable only for the most daring and acclimatized individuals. Always exercise caution in alpine waters.
The trails to Mattenalpsee encompass diverse terrain, ranging from dirt roads through alpine pastures and forest paths to steeper, moderately exposed sections with loose rocks. Hikers should be prepared for rugged mountain paths and potentially challenging conditions, especially early in the season when remnants of avalanches might still be present.
