This round tour can be started in Rhäzüns, at the Reichenau-Tamins trainstation or in Rothenbrunnen. Before you arrive in Domat/Ems, follow the forest road to the right side. That's the start of the rather long and quite steep ascent to Feldis.
From Feldis the ascent continues but less steep and after a short time you will reach the highest point of the tour. From there a descent of 1'000 meters in height begins and passes Dirauls and Scheid and ends in Rothenbrunnen.
From there follow first on the road and later on the trail back to Rhäzüns.
