Topo guide to bolted valley and mountain crag climbs from F3a - F6b in in the centre and west of Switzerland, covering the area south and west of Interlaken, Meringen, and the Grimsal Pass (and including these areas too). It includes a selection of crags from the Bernese Oberland, and the Valais (Wallis) Alps (Zermatt, Sion), many crags around Martigny, and even a dozen venues in the Chamonix and Annecy areas of France, making it the most useful of these Swiss guides for "Brits on their annual hols".
