Today has seen 0.6mm of light rain with high humidity (88%), but the rock had three excellent drying days prior (Aug 11–13) with warm temperatures and low humidity. The south-facing aspect and partial wind exposure should allow surface moisture to clear relatively quickly, but conditions need visual confirmation on arrival given today's dampness and the unsettled forecast ahead.

Based on weather conditions only — does not cover bird nesting restrictions or other access issues.

Site Details

Arguably the best bouldering in the Llanberis Pass, on the south side above the Climbers' Club hut. Around 238 problems on superior quality rhyolite with distinctive stratified formations. The 15–20 minute uphill approach keeps crowds thinner than roadside venues. Named after the classic Wavelength problem (V8).
