The crag is a sea-cliff, about half of which sits above a big rock platform known to climbers as the Dancing Ledges and is therefore always accessible; the other half is accessible by boulder-hopping at low tide, or by abseil, sometimes using hanging belays. The rock is limestone, of good clean quality. Its texture varies from smooth, in the few small areas recently exposed by rockfall, to a sharp popcorn texture which provides excellent friction. Most climbs follow steep finger-crack lines, and protection is usually good. The current guidebook, published in 2008, lists about 170 climbs, nearly all single-pitch, with grades up to E7 6c. Most climbs are in the medium-to-high grades; there is little quality climbing below VS grade.
