Site Details

A strong contender for the best bouldering in North Wales, on a hidden plateau above the Ogwen Valley. Around 78 problems (V4–V12) on superb volcanic rock. The perched position catches all available wind, so it dries quickly after rain. Steep 15-minute scree approach keeps crowds down. Quality of rock is exceptional.
