Crag features

A marvellous collection of routes, including steep wall climbing as well as the famous slab itself - which has such delights as Red and Yellow and Pink and... (E2 5a), Pull My Daisy (E2 5c) - the poor man's Dervish - up to Poetry Pink (E5 6a) and of course The Very Big and Very Small (8c+ - you disagree? You try it). Also has steeper stuff like Bela Lugosi Is Dead (E1 5b) and the pumpy Colossus (E3 5c).

Approach notes

Shorter, but a harder slog from the Vivian Quarry car park. Head up two sets of the rising rails and then around a path. Gently through the fence, scramble down scree and over stream to the Colossus area; around for the Slab. Or abseil rather than crossing the fence.
From Bus Stop, head to Dali's Hole and then take a meandering path R from the main path beside the pool.

Access Advice

May 2017 Update - a substantial rockfall has occured on the tower (known as Trango Tower or Y Ceiliog) containing the Plateau Slabs routes. As a result the landowners have cordoned off the whole Plateau/Peppermint Tower area and substantial ground works are being carried oput by contractors.

 Access to climb at these venues (Trango Towers/Peppermint Pig areas only) is no longer possible. Access to Rainbow slabs and surrounding areas from the Llanberis side remains unchanged but access from Nant Peris (Pass side) could be restricted when contractors are carrying out work.

This area includes all of the lower part of Dinorwig Slate quarry, including Rainbow slab area, and the levels opposite. The Lower Dinorwic quarries  are all on land owned by  First Hydro Company (FHC). FHC have to comply with the Mines and Quarries Act. This means providing a properly maintained barrier to prevent members of the public from falling into the quarries. The company are repairing fencing in the area and employing additional signage to emphasise the dangerous nature of the quarries. There is no formal permission to climb or walk in the quarries away from the public footpaths.  Please respect the environment of the quarries, do not damage any fences, keep dogs under control and take all litter home with you. In order to protect the current sensitive access, climbers have agreed not to climb on any of the levels below the Rainbow level or on the large tower overlooking the power station buildings.

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.
