The 54 walks in this guidebook explore the popular region around Mont Blanc. These routes showcase the best mountain walking to be found on both the French and the Italian sides of the Mont Blanc massif. The 50 contrasting day walks (3-20km) range from high-level walks to easy summits, mountain huts, viewpoints and mountain lakes, as well as less strenuous valley walks. Also included are four multi-day treks: Vallorcine to Plaine Joux, Vallorcine to Servoz, the Tour of the Aiguilles Rouges and a circuit of the Italian Val Ferret. Walks are organised according to the nearest town base: St Gervais les Bains and Les Contamines, Servoz and Plateau D\'Assy, Les Houches, Chamonix, Argentiere, Vallorcine and Courmayeur. Walks are Graded 1 to 3: grade 1 walks are manageable by any reasonably fit person on good, usually waymarked paths, while grade 3 routes are long, tough routes, often without waymarking, making navigation difficult: there could also be some scrambling. Additionally there is often a valley walk that can be done whatever the weather, or on rest days, with children, by bike, or as a run. All routes feature a detailed route description and mapping. 66 maps114 colour photos
