By Martyn Farr. Paperback, 1977. 126 pp. Darworld recounts the history of the exploration of the myriad of caves within Llangattock mountain. Lavishly illustrated, with pictures and dated surveys, this book deals specifically with the exploration of one mountain. Over the course of the past 50 years a series of dramatic discoveries has led to the establishment of one of Britain's longest cave networks, a system now well over 70 km in length. Highly acclaimed in international reviews, this is no dry and crusty compilation of events. This book recounts the spirit of adventure and outlines the dramatic events as they unfolded.
