Le Coin is the largest and most concentrated with multiple pads often stashed under boulders as well as a large orange gym mat that is usually left at boulder 15. Easily accessible by car by parking here: and walking up the path to the right at the tap. Also accessible by taking the line M bus (Mon-Sat) to Collonges-Sous-Saleve, Bourg d'en Haut and walking around 20 mins from there.
Problems are marked by a black arrow. Most are not named so when adding in unnamed boulders please ignore "Sans Nom [ROMAN NUMERAL]" and instead use the following naming convention: Bloc x Sans Nom y where x is the number of the boulder according to the cactus sports June 2019 topo and y is the number of the problem; working left to right and leaving traverses until last.
