About this trail
The TMB circles the entire Mont Blanc massif through France, Italy, and Switzerland — crossing mountain passes, glacial valleys, and high-altitude ridgelines with Europe's highest peak always in view. The route passes through iconic Alpine towns (Courmayeur, Champex, Les Houches) and chains of mountain refuges (refuges) serving full meals and dorm sleeping. No permits or booking required for the walk, but hut accommodation must be reserved months in advance in peak season. One of Europe's great long-distance trails.
