Salida
Les Contamines-Montjoie · 1164 m
Llegada
Les Chapieux · 1551 m
From Les Contamines climb past Notre-Dame de la Gorge, an ancient Roman way, to the Col du Bonhomme (2,329 m) and the Col de la Croix du Bonhomme (2,479 m), in stern, often snowy terrain. Descend into the pastoral Chapieux valley (1,554 m).
The most alpine stage on the French side begins on a Roman road: beyond the baroque sanctuary of Notre-Dame de la Gorge, the stepped paving climbs the torrent-cut gorge, in use for two thousand years. The glacial shelves of Nant Borrant and La Balme follow — both with refuges and water — then the landscape turns mineral: the Plan des Dames with its legendary cairn, the Col du Bonhomme, and finally the high traverse to the Croix du Bonhomme, often over snowfields even in midsummer. The drop to Les Chapieux is quick, through sheep pastures with marmots everywhere.

Ciencias de la Tierra
Geología y paisaje
The Mont Blanc massif is a Hercynian granite batholith (~300 million years old) uplifted by the Alpine orogeny: the pale Mont Blanc granite — the “protogine” — forms the Peuterey and Géant spires. At its feet the tour walks on older crystalline basement rocks (gneiss and micaschist) and, in Val Veny, on the Mesozoic limestones of the Pyramides Calcaires, a sliver of sedimentary cover pinched between the granites. The Miage and Brenva moraines are textbook examples.
Historia y cultura
The Roman way of Notre-Dame de la Gorge linked the Tarentaise to Mont Blanc: its natural bridge and stepped paving have been walked for two thousand years; the baroque sanctuary has drawn pilgrims since 1690.
Fuentes de agua
Water at the stage's support points (Les Contamines-Montjoie, Les Chapieux). On the high ground and at the passes springs are not guaranteed: fill bottles in the valley and at the huts.
Cómo llegar
Cross-border stage: on the foreign sides local public transport applies (PostAuto in Switzerland, line buses in France/Piedmont). Check seasonal timetables; in peak season several access links run by reservation only.
