the tour du mont blanc is a 11 day 170km circular walk. it can be gruelling one minute as you ascend or descend but incredible the next as you reach a summit and feel that you are within touching distance of either a glacier or just a sheer wall of rock that towers above you. from a photography angle it sets all sorts of challenges, of which climate, terrain, and just sheer exhaustion were three. we were lucky to experience superb weather all the way through and managed to come home with several thousand images of which a selection can be found here.
