Col du Sabot by bike from Allemont
Perched at 2,100 m above Vaujany, the Col du Sabot is one of the highest road mountain passes in Isère — and one of the least known. Since the Verney Dam (Allemont), the climb unfolds 16.9 km and 1,342 m of elevation gain An average gradient of 7.9% over %, leading to a cul-de-sac near the mountain pastures. A long, steady climb offering a rare sense of solitude, at the foot of the Grandes Rousses.
Difficulty
The slope is sustained and constant : much of the climb is rarely ridden, with gradients of up to 12 % and very few flat sections to catch your breath. The upper part, on a narrow and sometimes damaged road, crosses deserted mountain pastures all the way to the summit. Make sure you bring water and a windproof jacket: there are no refreshment points above Vaujany, and the top of the col is often swept by the wind.
A confidential mountain pass, never climbed by the Tour
Unlike its neighbours Croix de Fer and Glandon, the Col du Sabot has never been borrowed by the Tour de France : it has remained a secret among connoisseurs. From the summit, the view looks down onto the Grand-Maison Dam and the glaciers of the Grandes Rousses. A return trip from Allemont or Bourg-d’Oisans makes for a superb excursion away from the main roads.
