From the Frassati refuge, you head north-east to the Col des Ceingles at 2817m before descending into the Comba des Thoules and then climbing briefly to reach the Col de Saint-Rhémy at 2563m.

After a few twists and turns downhill, the path joins Praz de Farcoz and the route du Grand-Saint-Bernard above Fonteinte to finally reach the Col du Grand-Saint-Bernard, its hospice and its famous dogs!
