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).

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.
