CWM Silyn & Cwellyn, is a slim but beautifully produced Welsh rock climbing guidebook.
The guidebook has colour photo-diagrams in place of crag drawings. The guidebook covers the area south of Llanberis, and north of Tremadog. Crags covered include 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. The guidebook 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. Featuring a mix-ture of high mountain and low lying crags and routes of all types and standards.
