The Col de Bostan (unmarked route)

© The Col de Bostan (unmarked route) - SIVHG

This circuit is a classic of the valley, traveled indifferently from the refuge of La Golèse or Bostan. The Bostan pass marks the border with Switzerland.


Follow the wide path at the bottom of the parking area. It climbs steadily into the pretty Bostan forest, which you leave at an altitude of 1450m. Continue to the Bostan mountain chalets.
The view opens up onto the splendid Bostan valley, bordered on the right by the Dents D'Oddaz. Continue either along the left-hand combe, leading to the Bostan refuge, or the right-hand combe leading directly to the Lac des Verdets (obviously invisible at this time of year) nestled in a narrower combe.
The Bostan refuge has a small chalet behind it which is open all winter.

Shortly after this passage the slope rises a little to reach the pass. The sign at the top marks the border with Swiss territory.
The view is of the very slender Dents du Midi and the Val d'Illiez.

On your right, the Dents Blanches massif and the Col du Pas au Taureau. A few metres further down towards the Pas de La Bide is the small Swiss rescue hut of Bossetan (spelled Swiss).

The descent is made by the same route.
