The rock has had roughly 24 hours of drying since the last light rain (1.3mm on May 6th), with today remaining dry and moderate southerly winds aiding evaporation on this south-facing venue. However, several days of light but persistent precipitation (May 1–6 totalling ~9.3mm) combined with high ambient humidity (~73–81%) mean some seepage areas and sheltered faces may still hold residual moisture.

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).
