The Surselva, i.e. the Bündner Oberland, has a lot to offer in terms of mountainbiking, especially in the lowest region around Laax and Ilanz. On the three-day Hüttentour through the alpine mountain world of the Surselva, two of the most extraordinary mountain huts are approached: the Ustria Staila in Siat and the Péz Terri in Vrin. But the route also has class when it comes to trails. With the Flimserwald, the singletrail descent from Siat, the Val Lumnez and the Tomül Pass, some of the really big but little-known trail highlights of Graubünden are on the schedule.
