The area is access sensitive
🚗 Check the map to find the parking, it's in front of the electric installations. You can park in the big parking.
🚶♂️ Follow the trail on the map. You reach the "Pisciculture" (Parking there is tolerated if not too many car, please be respectful) and you find the first boulder at the beginning of the forest. It's an easy 2-5min walk.
No special rules, but of course bring back your trash and don't be too loud.
As it becomes popular, it's really important to not leave any trash in the forest! Thanks!
