Welsh Light - The Snowdon Range from Carreg Hylldrem © Nicholas Livesey

Crag features

The rock type, felsite, gives very steep climbing on odd, smoothish rock: not for slab climbers. Single- and multi-pitch routes up to 220ft, including Hardd (E2 5c) and the "out there!!" route of Samurai Groove (E3 5c).


According to Boulder Britain: This is the place where Jerry Moffatt started bouldering.

Approach notes

Lies immediately above the A4085 Aberglaslyn to Penrhyndeudraeth road, about 1mi N of Carreg.

Park in roadside bay by a small stream, just north of a little bridge on a sharp bend (1mile) from Garreg, (3miles) from the A498 junction. The crag is visable when approached from Garreg direction.

The bouldering wall is behind the trees above. Skirt the fence on the right, by the track, and wander left to the wall.


The Snowdon Sherpa 97 bus runs from Porthmadog to Betws, via the road below the crag,

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.
