First you cycle through the historic Old town, cross the Plessur river and ride out of the city on a marked cycling path. Soon you get into the forest. At point 729 you can either take a left and ascent to Schönegg. On top you will enjoy gorgeous views into the surrounding mountain scenery (Calanda, Ringelspitz, Rhätikon, mountains around Flims) and the Chur Rhine valley.
For the descent cross the small alp and follow the narrow and technical single track on the right side. Two times you will cross the street and then follow it for a short track, befor finally you will ride a trail with lots of flow back to the city.
