Route n°1 : The departure across the Frange Verte Park makes a good warm-up before your legs tackle the steady climb to Jarrie.
From the plateau you'll discover an outstanding panoramic view of the surrounding mountains and the Etang de Haute Jarrie regional nature reserve. The return descent is on an amusing path in a lovely forest decor.
You'll find water at the departure point in Frange Verte Park and at Le Plâtre
