Description
From Saint-Rhémy climb along the ancient Roman road of the Gauls to the Great St Bernard pass (2,473 m), with its thousand-year-old hospice and famous dogs. Then descend into Switzerland’s Val d’Entremont, through the Combe des Morts and pastures, to Bourg-Saint-Pierre (1,632 m).
You walk through history: the climb to the Great St Bernard follows the Roman road of the Gauls — cart ruts are still visible in the rock just below the pass — marched by Napoleon with forty thousand men in May 1800. At the hospice, founded by St Bernard in 1050 and continuously inhabited for nearly a thousand years, you can visit the baroque church, the museum and the kennels of the famous St Bernard dogs. The Swiss descent crosses the Combe des Morts and follows the torrent to Bourg-Saint-Pierre, whose Romanesque bell tower carries a thousand years of history.

Earth sciences
Geology & landscape
The Grand Combin belongs to the Grand St Bernard nappe (middle Penninic): crystalline schists and gneisses of the Siviez-Mischabel zone, overlain to the south by the calcschists-with-ophiolites of the By valley. The great north wall above the Panossière hut shows the alternation of basement and carbonate cover; the Fenêtre de Durand is carved in the softer calcschists, ever the natural way between Bagnes and Valpelline.
History & culture
On the pass, the hospice founded by St Bernard of Menthon (~1050) has rescued travellers for nearly a thousand years; Charlemagne passed this way and, in May 1800, Napoleon with 40,000 men.
Water sources
Water at the stage's support points (Saint-Rhémy-en-Bosses, Hospice du Grand Saint-Bernard, Bourg-Saint-Pierre). On the high ground and at the passes springs are not guaranteed: fill bottles in the valley and at the huts.
Getting there
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.
