This is the comprehensive rock climbing guidebook to Llanberis Pass describing one of the oldest and best rock climbing areas in Britain. This is the 6th Edition of the Llanberis guidebook, but the text and crag diagrams (now colour photo topos) have been comprehensively updated from the previous edition, with the result a substantially improved guidebook. It covers all the major and minor crags on both sides of the Pass between Nant Peris and Pen-y-Pass except those that are in the Cloggy and Liwedd, and slate guidebooks. Also included are descriptions of the most popular bouldering areas in the Pass written by local bouldering guru Simon Panton and illustrated by 14 of his own photo topos and a number of action photos. Particular care has been taken to making the approaches, descents, aspects and optimum conditions for the climbing stand out. This includes the BMC's advice as to the best approach to Dinas y Gromlech to minimise the large area of ground erosion below the crag. Reprinted in 2019 the guidebook contains superb colour photo topos of the crags, plus there are eight photo plans complemented by both area and detail maps which show the location and approaches to all the cliffs and crags. Number of pages is 416. Size is 125mm x 180mm. ISBN is 9780901601810.
