Leaving Le Bourg-D'Oisans look for the D44 which becomes the D526 which becomes the D926 and takes you to the magnificent Col de la Croix de Fer.Cameras at the ready, it is simply stunning.
Additionally, also follow the D926 to the N6 and take the D902 up to the Col du Telegraphe. You will see loads of fit cyclists panting and wheezing on your way up to the top. Ride down the other side of the Col and you come to the pleasant ski village of Valloire. Plenty of hotels and restaurants to choose from. Dramatic scenery. Absolute biking heaven. We rode it in July 2008. A must ride route!
