Col du Jandri

Col du Jandri, one of the highest roads in Europe

The Col du Jandri is a high mountain peak at an elevation of 3.165m (10,383ft) above the sea level, located in Rhone-Alpes in the French Isère département. It follows the R1-2 trail. It's one of the highest roads of Europe. This runway forms the highest trafficable road in the Alps and includes very steep ramps.

The road is unpaved but passable by all-terrain vehicle. The track still stands winding, often stony, dusty and steep. The road is signposted as mountain bike cross-country course and is even used by motorized heavy vehicles. The way has some very steep ramps. You'll have to challenge some very steep grades which require both physical strength and a very low gear. It is a service road for the various ski lifts and cable cars of Les Deux Alpes ski station.

To reach the summit, starting from Les Clapiers (Le Bourg-d'Oisans), the ascent is 26.9 km long. Over this distance, the elevation gain is 2.458 meters and the average gradient is 9.1 %. The maximum slope is 16%. The final part is very steep and stony. This road is usually open throughout the summer. A panoramic restaurant is situated there at an elevation of 3,200 meters and provides amazing views to the Glacier Mont de Lans. This ride also crosses Col des Gourses, at an elevation of 2.565m (8,415ft) above the sea level. The road is asphalted to 1.730 m altitude, just above the highest houses on the side. Then the gravel road is good enough for cycling with a road bike on, but it is still quite steep and very dusty. It's one of the highest roads of the country.
