Despite gabbro's non-porous nature and rapid drying, today's 1.2mm of rain combined with 98% humidity and a persistently saturated atmosphere (95% average humidity over the past week) means surfaces are likely wet or at least greasy right now. The relentless winter rain pattern — 143mm in 28 days with zero consecutive dry days — leaves everything sodden, and while gabbro won't absorb moisture, the surrounding environment (landings, approach, seepage from cliffs above) will be thoroughly waterlogged.

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.
