This itinerary is a concentrated, high-impact trek that covers the western half of the Tour du Mont Blanc, beginning in the Chamonix Valley and concluding in the Italian town of Courmayeur. It is an ideal choice for fit trekkers with limited time or for those who wish to complete the full TMB over two consecutive years, as this section constitutes a logical and deeply satisfying first half.
This portion of the tour is often considered the wilder and more remote segment, traversing high, desolate passes in France before making the dramatic crossing into Italy. The journey covers approximately 70 km of rugged alpine terrain.
The trek is a point-to-point journey, not a loop. The logistics are straightforward: upon arrival in Courmayeur on the final day, trekkers can easily return to the starting point in Chamonix via a 30-45 minute bus ride through the Mont Blanc tunnel, with several companies offering regular services.
