Please refrain from climbing outside

Due to the ongoing spread of Covid-19, please abstain from climbing outside.

At UKC we are all climbers and we understand the strong urge to be outdoors as the weather is finally improving, but we feel this is no longer socially acceptable. You can read our statement here.

We have suspended the UKC Logbooks Top Ascents and Conditions pages and we will no longer accept ascents dated from 23rd March onwards. You can still upload your historic ascents.

Crag features

Steep in places; excellent rock. Pleasent sunny aspect and some good routes makes a visit worthwhile. Mainly multi-pitch to 50 metres.

Outside Edge and Kirkus Route are on the Cwm Silyn crag not this one

Approach notes

The crag lies in the cwm to the NW of Ffynnon Llugwy and is approached by traversing hummocky moraine from the path to Craig yr Ysfa. Approximately 40 mins walk from the road.

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.

Volunteer to moderate Craig Yr Ogof (Cliff of the Cave)
We rely on volunteers to moderate their local crags. You would check updates and approve climbs added to the database. It's a very easy job, and all you need is a guidebook and an hour or two each month. [ read more ]
