Rioupéroux is a small bouldering area close to Grenoble, in the French Alps. The boulders are made of Gneiss and there are some pretty good and hard problems.
This video shows some of the bests of the spot, and especially BackDown, a crazy dyno, and the first ascent of Malédiction assis which took me a lot of effort to finish it off!
Problems in order of appearance:
Le CAT - 8A+
West Coast - 7C+
Back Down - 8A+
Malédiction (assis) - 8C (FA)
