Ascent 1

From the parking at Bourg St Bernard, (by the tunnel entrance), follow the road to the bridge, then stay on the true right bank and go up the Combe des Morts to the Hospice at the Col du Grand St Bernard. Nearly always very well tracked.

Descent 1

From the hospice follow the road along the side of the lake, past the Swiss/Italian frontier and descend, (sometimes through a road tunnel,) to Montagna Baou (2356m).

Ascent 2

Go up the cwm between the Tour des Fous and the dominant rock on the right. Continue NW, then W to the summit.

Descent 2

By the same route

Variant (AD/S3)
For the descent, take a gully that starts at the col between the Fourchon and the Pain de Sucre, facing S. Superb slopes that go down to the Grand Saint Bernard road on the Italian side. Then climb back up to the hospice following more or less the line of the road.  This adds 250m of climbing but well worth it if the conditions are good.
