This itinerary covers the last seven stages of the classic TMB, from Courmayeur to Les Houches. Together with the 4-day Les Houches – Courmayeur section, it lets you complete the whole tour in two trips.
Courmayeur can be reached from Chamonix by bus through the Mont Blanc Tunnel in about 45 minutes; at the finish, Les Houches is served by the Mont-Blanc Express. The route crosses three countries, with the Grand Col Ferret (2,537 m), the highest point on the main route, as early as the second day.
