Salida

Les Houches · 1005 m

Llegada

Les Contamines-Montjoie · 1164 m

From Les Houches climb to the Col de Voza (1,653 m), where the Tramway du Mont-Blanc rack railway crosses the pass, then descend into the green Val Montjoie through the hamlets of Bionnassay and La Villette to Les Contamines-Montjoie (1,167 m).

A linking stage between the loop’s two great French valleys. From the centre of Les Houches climb — on foot, or shortened by gondola — to the Col de Voza, where the rack rails of the Tramway du Mont-Blanc cut across the pass meadow: the little 1909 train still runs to the Nid d’Aigle, gateway to the French normal route up Mont Blanc. The descent crosses Bionnassay, a jewel of rural Savoyard architecture with its hanging glacier behind, then rolls gently through forest to Les Contamines-Montjoie, the last full-service village before the Bonhomme.

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 Tramway du Mont-Blanc, opened in 1909, was meant to reach the summit of Mont Blanc: it stopped at the Nid d’Aigle because of the Great War. Bionnassay is today a protected hamlet with no new building.

Fuentes de agua

Water at the stage's support points (Les Houches, Les Contamines-Montjoie). 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.
