It is simply the East part of the Gorge aux Châts area. Most of the problems are located behind the crest (and long-drying) though other interesting ones are on its South-West face.
Caution: due to the houses, it is very important to park the car near the barrier (and not in front of the houses) and to access to the boulders by climbing up the crest from the classical sector.
Caution (October 2020): the usual parking lot is now strictly forbidden and motorists are regularly fined...
