The story of the Tour du Mont-Blanc is told through its passes. They set the rhythm of the trek, mark the borders and offer the views you still remember ten years later. Here is an overview of the crossings not to be missed.
The Col du Bonhomme and the Croix du Bonhomme
The first real climb of the TMB from Les Contamines, the Col du Bonhomme (2,329 m) and then the Croix du Bonhomme (2,479 m) set the tone: long, steady and exposed to the wind. This is the section that reveals whether the pace you have chosen is the right one.
Early in the season, snow patches can remain on the north side: check the state of the trail before heading up.
The Col de la Seigne: crossing into Italy
At 2,516 m, the Col de la Seigne marks the border between France and Italy and one of the finest moments of the Tour: the Val Veny opens up all at once onto the south face of Mont Blanc, the Aiguille Noire and the hanging glaciers.
The pass is often windy and offers no shelter. Keep a windproof layer somewhere you can reach without opening your pack.
The Grand Col Ferret and the Fenêtre d'Arpette
The Grand Col Ferret (2,537 m) takes you over into Switzerland, into the Valais Val Ferret, with a radical change of atmosphere: pastures, wooden hamlets, and a wide green valley.
Further on, the Fenêtre d'Arpette (2,665 m) is the high point of the most demanding variant of the TMB, facing the Trient glacier. Save it for sure-footed walkers and good weather — the alternative via the Bovine is still beautiful and far more sheltered.
