It is currently forbidden to climb in this area.

Due to a rock collapse, climbing is no longer allowed (August 2017). After Poigny-la-Forêt, on the D107 towards Guiperreux, park the car on the left and take the GR1 up to "Les Rochers d'Angennes". The area composes of a white circuit of 50 numbers and an old quarry (with a roof that is forbidden to climb).
