Crag features

West facing, open but sheltered from wind and quite pleasant on the eye for a quarry.

Routes up to 25m. Mostly steep solid slabs; on less-used routes there are friable holds. Belays are available at the top. The missing insitu gear (pegs) have been replaced with bolts on a number of lines.

Trad routes in the VS - E4 range, include the superb Owl and the Antelope (E2), On Jupiter and Mars (E1) & Fly Me to the Moon (VS) and should be on everyones essential sandstone tick list.

There are an equal number of sports routes between Fr.4 to Fr.7b. In the centre of the cliff are 5 excellent lines, including Western Front Direct; possibly the best Fr.7a in these parts.

A topo is available on the South Wales Mountaineering Club Website (see link below).

South Wales Sport Climbs

South Wales Sport Climbs covers the area to the south of the Brecon Beacons, spanning the land and sea cliffs from the River Wye on the Welsh border to Pembrokeshire in the west. The area is home to a wealth of sport climbing on a multitude of venues ranging from small inland quarries to extensive limestone sea cliffs.
More info
There is a wobbly block that contains the third bolt on relaxed ladybird. This bolt could do with being moved as it's highly unlikely to hold a fall.
