Paddy Dillon is a prolific walker and guidebook writer with over 70 guidebooks to his name, and contributions to 30 other titles. He has written extensively for many different outdoor publications and has appeared on radio and television.

      Paddy uses a tablet computer to write his route descriptions while walking. His descriptions are therefore precise, having been written at the very point at which the reader uses them.

      Paddy is an indefatigable long-distance walker who has walked all of Britain’s National Trails and several major European trails. He lives on the fringes of the Lake District and has walked, and written about walking, in every county throughout the British Isles. He has led guided walks and walked throughout Europe, as well as in Nepal, Tibet, Korea, Africa and the Rocky Mountains of Canada and the US. Paddy is a member of the Outdoor Writers and Photographers Guild.
