|Col du Lautaret|
|Elevation||2,058 m (6,752 ft)|
|Traversed by||Route nationale 91|
It marks the boundary between the valleys of the Romanche and the Guisane, a tributary of the Durance which has its source at the col. The valleys are linked by national route 91 (Grenoble – Le Bourg-d'Oisans – Briançon). The Lautaret is one of the lowest points on the ridge line which separates the "north" (mainly in the Rhône-Alpes région) and "south" (mainly in the Provence-Alpes-Côte d'Azur région) geographic areas of the French Alps.
The Col is open all year round and provides good views of La Meije to the south-west and the Grand Galibier to the north. It is also well known for its botanical garden managed by the Université Grenoble Alpes. The route to the south side of the Col du Galibier leaves from the Lautaret.
Details of the climbs
From the west, the climb starts at Les Clapier, near Le Bourg-d'Oisans, from where the climb is 34.2 km (21.3 mi) long, gaining 1,312 m (4,304 ft) in altitude, at an average gradient of 3.8%, with the steepest section being at 7.5% in the first kilometre.
Tour de France
The Tour de France first crossed over the Col du Lautaret in 1911, when the leader over the summit was Émile Georget. Since 1947, the Lautaret pass has been crossed over 40 times by the Tour de France, although most of these have not been classified for the "King of the Mountains" competition, usually when the pass is crossed on the descent from the Col du Galibier (As of 2014[update]).
