This book covers a large area west of Snowdon, including Llechog, Castell Cidwm, Craig y Bera, Cwm Silyn, Cwm Pennant, and Moel Hebog. Climbs range from Diffs that can be climbed in boots and take you to summit ridges to the more recent mega-routes of Pat Littlejohn and others on Cidwm and Craig y Bera. It also encompasses the roadside slab routes of Drws y Coed, some of the Joe Brown era's finest classics, and a good selection of winter gullies. This volume completes the extensive project of documenting the outlying areas south and west of Snowdon begun with the recent Tremadog and Meirionnydd guides. • Cwm Silyn by Bob Wightman and Paul Jenkinson (November 2003) • Artwork by Don Sargeant • Editied by John Willson • 128 pages of text and maps, and 28 pages of photos and diagrams • ISBN 0-901601-74-8 • £13.50
