The Tour of Mont Blanc is one of the best - if not the best - of the world's classic hikes. It circumnavigates the Mont Blanc massif in about eleven days. This new edition incorporates details of the new routes on the Italian section, as well as all other recent route changes and variants. The walk has all the excitement of the high mountains yet none of the worry of altitude sickness. It crosses numerous cols with stunning views of spectacular snow and rock peaks. Accommodation along the route is plentiful.The 'official' Tour du Mont Blanc follows an established route around the main block of mountains containing not only Mont Blanc but its principal allied summits. The author describes the tour both in the traditional 'anti-clockwise' direction and the 'clockwise' direction. There are several alternative routes that subsequently link, and these are also described. The routes, along with suggestions for alternative exploration, give what the author thinks is the very best perspective and appreciation of the whole region.
