The book covers the entire range - France, Spain and Andorra and there are well over 400 kilometres (250 miles) of walks in this guide, the equivalent of a coast-to-coast traverse - one of the 'classics' for all serious walkers. But you don't have to be an expert walker for any of hikes described in the book. None of them requires special skills (under summer conditions) and, if you are not very fit, simply turn back when you feel like it (there are short walk suggestions with most of the itineraries). Experienced and fit walkers will nevertheless find much to enjoy, for the authors have included some of the wildest scenery in the Pyrenees, walked pilgrim routes and World War II escape routes, climbed to summits (like Canigou), enjoyed the habitat of marmots, vultures and lizards (the Pyrenean chamois), and not neglected the great and the famous (like the Breche de Roland).
