Crag features

Three-star classic routes at every grade from VDiff (Spiral Stairs) to E8 (Nightmayer). The superclassics are Cenotaph Corner (E1 5c), Left Wall (E2 5c), Right Wall (E5 6a), Lord of the Flies (E6 6a). Often busy at Bank Holidays and warm weekends.

Approach notes

From the Cromlech Boulders head slightly left and go up alongside the stream before heading right towards the crags as going direct up the scree is painful. Parking can be limited - either arrive early or be prepared for a long walk.  Can also get 'Snowden Sherpa' (park and ride) from Llanberis.  The Boulders are at roadside. Needs dry weather but dries well.

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.
