"Corsica is a mountainous island in the Mediterranean and its GR20 is reputed to be the toughest waymarked trail in Europe. It is an ambitious route for fit and agile walkers, covering 190km in about two weeks as it makes a complete traverse through the high mountains, backpacking the whole way, sometimes with hands-on scrambling. Facilities are limited to a dozen mountain refuges and a mere handful of hotels or gîtes. The 'classic' route is described, along with high- and low-level alternatives, plus extra mountain climbs. The guide explains exactly what is involved in following the GR20, including what walkers need to carry and how difficult the route is in places, revealing everything you need to know. Detailed route descriptions and stunning photographs"--Publisher's description.
