From the Fiesch public transport hub, take the road towards Fieschertal up to the first left turn. Follow it until you can turn right onto a natural trail. You cross a bridge and stay on the path until a road branches left directly leading into the village of Fieschertal. After crossing it, pedal uphill and then continue towards the Fiescher Glacier. After some time, the paved road becomes a trail leading to Hobrigga. Cross the Wysswasser river and enjoy the descent on cool, easy singletrails back to Fiesch. At the height of Fiesch Obermatta, bike down into Birchi and take the turn towards Wiler. Stay on the natural trail until you meet the paved road above Lax. Follow it uphill for a short stretch, then take the singletrail branching right. At Wiler, ride down into the village and back via Birchi to the Fiesch public transport hub.
