Tour du Mont Blanc — Classic Trek

The Tour du Mont Blanc (TMB) is the most walked long-distance trail in the Alps and arguably in the world. The full circuit of 170 km encircles the Mont Blanc massif through three countries — France, Italy, and Switzerland — crossing nine mountain passes and covering 10,000 m of cumulative ascent.

The numbers

• Distance: ~170 km (full circuit)
• Typical duration: 7–11 days
• Cumulative ascent: ~10,000 m
• High point: Grand Col Ferret (2,537 m) — France–Italy border
• Countries: France, Italy, Switzerland
• Best season: late June–mid September

The experience

The TMB is exceptional in its variety: from the chaotic glamour of Chamonix to the quiet Val Ferret in Italy, to the gentler Swiss pastures around Champex and Trient. Each country segment has a distinct character. The huts (refuges) range from sparkling CAF refuges with four-course dinners to tiny Italian rifugi with handmade pasta. Booking months ahead is essential for July–August.
