About Trevallen

Trevallen Pillar (E1 5b), Deep Space (E2 5b), Point Blank (E1 5b)","Trevallen is a compact yet formidable limestone crag situated on the South Pembrokeshire coast near St. Govan's Head. The rock character consists of dense, highly pocketed limestone with crisp vertical crimps, steep crack features, and flat non-tidal belay platforms. Facing south, the cliff captures full sun throughout the day and dries almost immediately after rain, though salt spray can coat footholds during high seas. The venue features physical, sustained traditional wall climbs mostly in the E1 to E3 bracket, headlined by classic lines like Trevallen Pillar and Point Blank. The approach takes roughly ten minutes along flat cliff-top paths from the main St. Govan's parking area. Because the crag sits within the Castlemartin military area, access is subject to range firing closures.
