The new Central Wales guidebook has just been published and contains all you need to know about this previously undocumented area between Machynlleth and Pembroke. The area has seen extensive development of bouldering, sea cliff climbing, bolted quarry routes and long pitches on remote mountain crags.
It is incredibly well researched and documented with a great history and maps that even I can follow! Plenty of action pictures giving an idea of scale and rock quality and all very inspiring: the two main authors Dave Williams and Doug Kerr have explored a huge area of central Wales along with a small band of devotees whose energy and enthusiasm spill over in each page. Highly recommended!
