glorious traverse of the Pyrenees, on the Spanish side, is a serious challenge - passing over a succession of high alpine passes where boulderfields, scree slopes and occasional snowfields may need to be crossed - but it is now well waymarked and has regular opportunites to top up on food and drink, described within the routes and in a detailed place-by-place appendix at the back. Also included are bad weather options - although the weather is often good along this route - detours to find accommodation at some points, and advice on accommodation, supplies, language and logistics, as well as a glossary including Aragon, Basque and Catalan, to help you find your way.
