Crag features

A very good crag for the sub-E1 climber, plus some thuggy delights for those on E2 or above. The rock is mostly good but beware the organ-pipe shapes: these can be unstable.

Multi-pitch routes up to 200ft, including the very popular Wrinkle (VD), Crackstone Rib (S), Overlapping Wall (E1 5c), Erosion Groove Direct (E2 5c) and - for the thugs - Zangorilla (E4 6a).

Approach notes

Up the Pass between Clogwyn y Grochan and further down from the Cromlech, opposite the Climbers' Club hut on the south side of the Pass.

Rockfax App

North Wales Climbs

North Wales Climbs covers the best climbing from the whole of this huge and varied area. The book is modelled on the very popular West Country Climbs which set a new standard for selected climb guidebooks back in 2010. It contains all the routes from the 2010 publication North Wales Classics and many more routes and areas, with expanded descriptions and much bigger photo-topos. The book covers all the major mountain crags from Llanberis Pass, to Cloggy; and from Ogwen to the Carneddau. It also includes the Llanberis Slate quarries, Tremadog, the Moelwyns, the Gwynant Valley, Mid-Wales, Gogarth and the North Coast Limestone.
