Easy stretches where you can glide along alternate with more challenging sections; there are some strenuous climbs and speedy descents. From where it starts by the municipal building, the trail first takes you along below the villages of Sedrun and Rueras. In Dieni you pass the ruined castle of Putnengia. It is thought to have been built in the 13th century by the lords of Ponteningen and was inhabited for over 200 years. The family, who came from Disentis and had Walser roots, was put in charge of Tujetsch.
After a few more loops, you reach the lowest point of the trail and ski alongside the Rhine – sometimes through the forest and then across open fields again. After the power station comes an area which has now been renatured, having been the installation site for the NRLA construction project for over 20 years. So now it is accessible to cross-country skiers. The gently climbing section back to Sedrun is also there thanks to the NRLA project: the temporary rail access to the construction site has remained in place and in winter forms part of the cross-country skiing trail.
If you include all the loops, the complete circuit is about 14 kilometres long. However, it can be shortened or extended in various places as you please. Less energetic skiers would do best to ski along the valley, starting at the power station.
