A series of short limestone cliffs running along the coast from Benllech. There is an appealing spread of sport and trad routes throughout the F5c - F7b and VS – E3 grade range. Many of the routes were originally climbed in 1991, and the whole area was re-equipped over the winter of 2007/08. None of the crags are major venues, but the seaside resort ambience, ease of access and generally non-serious nature of the routes all add up to an attractive prospect.
The rock is compact and tightly banded limestone, giving rise to clean open walls, typically dotted with numerous horizontal edges and cleaved by the occasional vertical crack or narrow groove system. Some snappy holds should be expected. Most of the routes, including some of the trad routes, are equipped with bolt lower-offs or bolt belays.
Another similar area of bolted limestone sea cliff has been developed at Fedw Fawr, near the eastern tip of Anglesey.
Most of the crags are tidal to some degree or other. The north/east aspect ensures that sunshine is mostly restricted to the morning. All of the crags are quick drying, and seepage is rarely a problem. The barnacled lower sections of the tidal crags do stay annoyingly damp, although on a breezy day this is less of an issue.
All the crags can be reached from the coastal footpath which runs from the main Benllech bay. Most of the crags are situated to the north, 1-2km from the bay.
