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

Black rock which often looks wet (and can be slow to dry out). Steep, despite appearances. A serious cliff though the rock is fine. Multi-pitch routes up to 230ft, notably Zig-Zag (VS 4b), Black Wall (E1 5c) and Yellow Wall (E2 5b). Also a huge HS traverse, The Black Belt.

Approach notes

Given its position just above Beudy-Mawr near the bottom of the Llanberis Pass, car parking may be hard. Slog up from the road.

Rockfax App

Available in the Rockfax App

The Rockfax App brings together all the Rockfax climbing information with UKC logbooks and presents it into a user-friendly package for use on Android and iOS devices.


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.

North Wales Classics

A significant addition to the Rockfax stable; North Wales Classics is a pocket-sized guide packs in hundreds of superb routes throughout the mountains of Snowdonia. From Tremadog to Tryfan, and everywhere in between, the book covers mid-grade routes on the best crags and features top-notch photo-topos and inspirational action shots taking you where you want to go.
