The Alps rank high among the world's foremost destinations for canyoning. This book brings together 90 of the most celebrated descents in the Alpine regions of northern Italy and Ticino in Switzerland. Divided into five areas, the descents described in the guide present a huge variety of terrain, rock and styles of canyoning. Route difficulty is split into seven grades, from easier canyons suited to beginners, through to the strongest aquatic and technical challenges, which demand experienced rope skills, physical fitness and a calm head for high water.

The Alps are home to some of the most extraordinary geological creations in the world, and the range's canyons are no exception, from limestone to granite-gneiss aquaparks. Sights to tempt any canyoner await; from the arty sweep of water-carved rock, to knife-thin chasms reaching overhead, to serene blue pools cradled in a natural ampitheatre.

The guide introduces routes in Val d'Ossola, Ticino, Lake Como and the Belluno Dolomites through to canyons in Austria and Slovenia. There is information on Alpine geology and the history of Canyoning, as well as details on access and accommodation in each area, advice on technique, risks, preparation and necessary equipment. It is an indispensable companion to any canyoner looking for an exhilarating adventure in the Alps.
