Distance, Duration and Difficulty Level

The Tour du Mont Blanc is a demanding trek requiring good physical condition and serious preparation. At 170 km long and with over 10,000 meters of elevation gain , this major hike is not for beginners. While most hikers complete the circuit in 7 to 10 days, it is possible to adjust the duration depending on your pace and chosen routes. Some more technical or exposed sections can be bypassed, while others offer more spectacular alternatives for those who love high altitudes and panoramic views.

The start and finish are usually in Les Houches , a small town near Chamonix . Most hikers choose to hike this long-distance trail counter-clockwise, which allows them to climb the steepest slopes at the beginning and finish with more gradual descents.
