Hazards & advisories
Huts, cols & altitudes
The classic 170 km circuit of the Mont Blanc massif through France, Italy and Switzerland, anticlockwise from Les Houches: Col de Voza, the Contamines valley, the Croix du Bonhomme, Col de la Seigne into Italy, Courmayeur and the Val Ferret balconies, Grand Col Ferret into Switzerland, Champex and Trient, then Col de Balme and the Aiguilles Rouges balcony back to Chamonix. Weather risk is afternoon thunderstorms on the cols, late-lying snow on the north sides in June, and wind and cold on the 2,500 m crossings.

Bookings, access & safety
Tour du Mont Blanc questions
- Is the Tour du Mont Blanc open right now?
- No closure is currently reported in the news and official sources we monitor. The live score is 97/100 (Excellent).
- When is the best time to walk the Tour du Mont Blanc?
- Best season: mid-June – mid-September (huts staffed). Check hut opening dates, and expect afternoon thunderstorms in summer and snow on the high cols outside it.
- How high does the Tour du Mont Blanc go?
- The highest point we track is Grand Col Ferret (2,537 m). No overnight stop is above 3,000 m; the challenge is the daily climbing and weather on the cols.
- Do I need a permit or bookings for the Tour du Mont Blanc?
- Hut and gîte bookings — Book every night in advance for July–August; many huts use the shared booking site montourdumontblanc.com — confirm with each hut.; Travel documents — The route crosses the Italian and Swiss borders on foot: carry a passport or national ID card. Rules change — confirm with the refuges and park authorities.
- Where does the avalanche level come from?
- From the official Météo-France avalanche bulletin (BRA) for the massif — or the Swiss SLF bulletin on Swiss stages — whenever one is in force (early November to early June). Otherwise the level shown is a model estimate and is labelled as such.
- How is the Tour du Mont Blanc score calculated?
- Hourly forecasts for every waypoint, corrected to its real altitude (MET Norway Locationforecast), feed six factors: weather on the cols (wind, cold, cloud, thunderstorms), snow and avalanche danger, rain against published European landslide thresholds, trail weather, views and access. Météo-France orange/red warnings, flood vigilance and credible closure reports cap the score.
Weather forecast from MET Norway (CC BY 4.0). Not an official forecast. Always follow Météo-France warnings and avalanche bulletins, préfecture and park notices and refuge guardians. Emergency: 112.
