Col de l'Échelle (also known as Colle della Scala), at an elevation of 1.762m (5,781ft) above the sea level, is a high mountain pass in the Alps in the department of Hautes-Alpes in France. It connects Vallée de la Clarée and Vallée Étroite, commune of Névache. The col is next to Bardonecchia in Italy.
This pass and the slightly higher Le Mauvais Pas (1.779m) is only a kilometre apart on each side of the flat pass stretch. This pass is actually the lowest pass across the Western Alps. The surface of the road is asphalt, and chains or snow tyres can be required anytime.
There are 2 possible routes to reach the summit. From La Vachette (in France), the ascent is 17 km long with a gain of 391 meters and an average percentage of 2.3 %. And from Bardonecchia, the ascent is 8.84 km long, gaining 476 meters and an average percentage of 5.4 %.The road is better on the Italian side, but the two unlit tunnels near the top requires care.
