Despite gabbro's non-porous nature and fast drying, today's 100% humidity, active rainfall from mid-afternoon, and saturated conditions from recent days mean the rock will be wet and slippery. The coming week offers no meaningful dry window, with rain forecast every day through June 20th.

Site Details

The most popular gabbro bouldering area on the Lleyn Peninsula coast — a remote, beautiful beach setting. The gabbro rock is extremely rough and textured, providing superb friction (bring tape). Semi-tidal: some boulders only accessible at low tide. Landings are generally poor and require multiple pads. Around 42 problems across the grades.

Condition Notes

Non-porous gabbro dries very quickly — can often be climbed shortly after rain. Exceptionally rough texture provides good friction even in marginal conditions but is brutal on skin. Semi-tidal: check tide times as some boulders are only accessible at low tide.
