Red Wall (HS 4b), The Red Spot (VS 4c), Amigo (HVS 5a), Porth Clais Pillar (VS 4c)","Porth Clais is a charming, accessible coastal inlet venue situated just south of St. David's in North Pembrokeshire. The rock character features colorful pre-Cambrian igneous rock and quartz-inserrted walls, offering positive crimps, clean jamming cracks, and non-polished slabs. Facing west across a narrow, sheltered sea inlet, the crag catches afternoon sun and dries very rapidly after rain showers. The route selection is renowned for high-quality lower and middle-grade traditional climbing from Diff up to HVS, with Red Wall and The Red Spot drawing steady crowds. The approach is extremely simple, taking under five minutes along flat footpaths from the Porth Clais harbour car park. Non-tidal access makes it ideal for flexible sessions, though wind exposure can be high.
