Today is the first dry day after a very wet week (51.8mm in 7 days), with the last rain falling early on April 12. The south-facing aspect and moderate winds should have dried exposed surfaces, but seepage, sheltered areas, and high ambient humidity mean conditions need on-ground verification before committing to climb.

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).
