INFO 16/03/21: Forestry work in progress, circuit not recommended. For experienced mountain bikers. After a first long ascent with irregular slopes in the wood of Servelongue, join Massieu by a very technical descent.
A second, more regular ascent will bring you to Lake Saint-Sixte.
The shaded surroundings of Lake Saint-Sixte (highest point of the circuit at 700m) will be ideal for recovering before starting a rapid and technical descent in the undergrowth, where you will have to use natural support!
Warning: fording on the path leading to the castle of Longpra.
You cross one of the richest natural sites in the Isère department (Natura 2000 zone, stay on the path).
