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

Llech Ddu is a magnificent crag of great character. Complex rock architecture makes the structure difficult to comprehend at first acquaintance. Multi-pitch routes to 140 metres. Note that all in-situ pegs should be backed up! They tend to be rusted to crumbly rubbish. Why not try your hand at the 450ft, six pitch *** E1 "The Groove"?

Approach notes

Approach as for Ysgolion Duon, but striking up the screes to the base of the crag after about one hour.

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.
