Mountain Bike

Discover the valley end of the Diemtigtal Nature Park with its steep cliffs, mountain forests and alpine pastures on the "GrimmialpBike" route.

Over a distance of around 18 kilometres and more than 650 metres in altitude, the Bernese Oberland mountain valley with its extensive cultural landscape is a recommendation for active holidays. The varied mountain bike route leads through Switzerland's most important alpine farming community.



The tour starts in Tiermatti, Schwenden. At the beginning, the trail leads out of the valley into the Höllersberg forest and on the gravel path through the Balmi forest up to the lower Gurbs. The challenging descent into the valley takes place shortly before the alpine hut, turning right. It follows the old Gurbsweg down to Schlatti. We advise less experienced riders to exercise caution and to push the bike in some places. The rather leisurely ride along the Schattsite into Grunholz to Egg once again shows the extensive cultivated landscape. Once you're properly warmed up, you tackle the most challenging section up to Hintere Nydegg. From there you head out of the valley on beautiful forest roads to Tiermatti. 

Follow the red signposts with route field no. 916 - they show you the way.

Safety guidelines
