The author of the internationally bestselling The Walker’s Guide to Outdoor Clues and Signs and How to Read Water will lead a walk up Offa’s Dyke talking about his new book Wild Signs and Star Paths: The Keys to Our Lost Sixth Sense, showing how it is possible to achieve a level of outdoors awareness that will enable you to sense direction from stars and plants, and forecast weather from woodland sounds. A member of the Brecon Beacons National Park team will join the walk.
