A fantastic mountain trail. Entry point can be difficult to spot. Starts with a short hike-a-bike before the terrain opens up. First half is quite techinical and demanding, but rideable. Magnificent view from the highest points. Many small mountain lakes. From there down it is a wonderful endruo trail, but requires some pedalling. Lots of exciting drops, roots and other challenges before you end up at Haus Sachsen. Watch out for hikers.

Access Info

Drive or pedal up to Knutehytta, hve lunsj, roll back the gravel road a couple of hundred metres before the trail begins through the bush on the left.
