From Barbizon, follow l'Allée des Vaches to the East, and park the car at the refreshment bar of La Caverne aux Brigands. The area of "Apremont Vallon de Sully" gathers the boulders (most of them without arrows) to the right of la route des Gorges d'Apremont. Follow La Route Marie-Thérèse for 600 m from La Caverne aux Brigands, take La Route des Gorges d'Apremont for 100m at an old parking lot. Most of the problems are along a small path to the right of La Route des Gorges d'Apremont, just before Le Piano à Queue (red n°4).
