"Geneva's best indoor climbing? Strictly speaking, this is bouldering only - there are no ropes here, the climbing is on short, steep walls above thick crashmats. Steepness varies from vertical to seriously overhanging, with a large cave, and a small slab thrown in for good measure. There is a bar upstairs, and a loud soundsystem to psyche you up. Entrance is cheap at 10chf per session (or 150chf per trimester). Free climbing shoe rental! Minimal changing facilities."
