The Cromlech Boulders are currently wet and unsuitable for climbing. Today has seen nearly 10mm of rain with 98% humidity, following an extremely wet period with over 70mm in the last 7 days and zero consecutive dry days — the rhyolite surfaces will be slippery and dangerous.

Site Details
The most iconic bouldering venue in North Wales, roadside below Dinas Cromlech in the Llanberis Pass. Rhyolite boulders with problems from V0 to V13 including Jerry's Roof (V8). Extremely easy access but can get very crowded on weekends. The volcanic rock can be slippery when wet.
