This is a difficult mountain bike ride, requiring very good physical fitness and advanced riding skills. The trail features technically demanding sections with a Single Track Scale (STS) rating of S3-S6, meaning you'll encounter numerous large boulders, significant root passages, and higher steps. Excellent bike control and continuous concentration are essential.
The terrain is highly varied and technically challenging. You will encounter blocked single trails, hairpin turns, and tricky traverses. Surfaces can be slippery or composed of loose scree, with gradients exceeding 70% in some sections. Be prepared for demanding ascents and descents, and potentially needing to push your bike through certain parts.
The loop offers breathtaking scenery of the Swiss Alps. You'll experience a Steep Ascent from Elson, ride through a Singletrack Through the Woods, and enjoy a magnificent View of the Dents de Veisivi. The route also passes traditional 'mayens' (alpine chalets) and offers vistas of authentic villages in the Evolène region.
While specific parking details for the trailhead are not provided, Evolène is the starting point. You should look for public parking options within the village of Evolène, which serves as a hub for many trails in the region. It's advisable to arrive early, especially during peak season, to secure a spot.
