Col d'Ornon (1,360 m (4,462 ft)) is a mountain pass through the Dauphiné Alps in the department of Isère in France which connects the communities of Le Bourg-d'Oisans and La Mure. The climb is used occasionally in the Tour de France cycle race, including on the "Queen stage" on 18 July 2013 which finishes with two ascents to Alpe d'Huez.
