The Wales Coast Path from Porthmadog to St Dogmaels

As part of the Wales Coast Path, the Ceredigion Coast Path and Snowdonia Coast Path trace a curve of 233km (145 miles) of coastal and inland walking down Cardigan Bay. This guidebook describes a 16-stage guide to the walk from Porthmadog to St Dogmaels covering the trail between the Llyn Peninsula and the Pembrokeshire Coast Path. The route is illustrated with OS map extracts as well as extra sketch maps of tricky sections and lots of information is included about public transport links, accommodation and facilities to help you plan how to tackle the trail. Stong walkers could complete the full walk in just less than two weeks, but it»s also worth considering building in rest days in order to visit, say Harlech Castle, or ride on of the narrow gauge railways.
