This relatively recent local crag climbs a lot better than it looks, and is right next to the road! The down side of it's proximity to the road is the full brunt of grenoble hoon noise.
Please support the local developers, and buy the online guide at https://climbingaway.fr/fr/. It's inexpensive, and updated frequently, even if the climbingaway app itself is a bit buggy.
Park. Then climb.
Glue and chipped holds are not uncommon
