Sheep Pen Boulders are currently saturated after an extremely wet period — 326mm over 28 days with rain again today and no consecutive dry days. Even though rhyolite is non-porous and dries relatively quickly, the persistent rainfall, 94% humidity, and cloud-level altitude mean surfaces will be wet and dangerously slippery.

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.
