Tour du Mont Blanc: The Complete Guide
The Tour du Mont Blanc (TMB) is the most famous long-distance alpine trek — a 170 km circuit around the highest peak in Western Europe, crossing France, Italy and Switzerland with roughly 10,000 m of cumulative ascent. It is a hut-to-hut trek with no technical difficulty.
It is the benchmark "first great trek" for fit walkers — spectacular scenery, comfortable refuges, and logistics simple enough to do independently.
Direction and Refuges
The classic direction is counter-clockwise from Chamonix, through Les Houches, over the Col du Bonhomme into Italy, around the Val Ferret, over the Grand Col Ferret into Switzerland, and back to Chamonix via Argentière. The route can be shortened using cable cars and buses at several points.
Refuges must be booked in advance for July–August. The optional Fenêtre d'Arpette variant (2,665 m) above Champex-Lac is the highest and most spectacular section.
Fitness, Gear and Booking
The TMB is within reach of any fit, regular walker who is comfortable with 6–8 hour days and around 1,000 m of ascent. No technical skills are required, but sturdy broken-in boots, layered clothing and full waterproofs are essential — alpine weather changes fast even in midsummer. Most walkers use a baggage-transfer service so they carry only a daypack.
Refuge booking is the main logistical task. For July–August, reserve every night months ahead through the individual refuges or a booking service; many walkers use a self-guided package that pre-books the refuges and transfers their bag between stops. Carry some cash for huts that do not take cards, and an alpine-club membership card for member discounts at affiliated refuges.
