The last significant rain was the 47.5mm deluge on April 11, followed by lighter showers on April 12 (7.8mm total, last drops around 16:00). Today (April 13) has been dry so far with moderate wind and dropping humidity — the exposed rhyolite should be drying, but given the enormous recent saturation (71mm in 7 days) and the 400m altitude, residual seepage and damp patches in sheltered spots are very likely. Climbers should visually inspect holds before committing.

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.
