The fourth edition of this popular Cicerone guide offers up-to-date information on walking the GR11 from the Atlantic to the Mediterranean in 44 daily stages. The GR11 is a truly high-quality, high-level mountain trail on tracks and footpaths. Affectionately known as 'La Senda' (The Track), it crosses the Pyrenees from coast to coast on the Spanish side of the border with France (mirroring the French counterpart, the GR10). A combination of spectacular high peaks, glistening tarns, deep green valleys and expanses of wild beauty -- in addition to a moderate climate and easy access -- make the range an excellent choice for the adventurous walker. The new full-colour edition of this guide offers a detailed account of the route and is illustrated with profiles and sketch maps. It also provides information on access to the region and the route, together with notes on flora and fauna, equipment and maps, accommodation, weather and access to water.
