> This route is signposted by the FFC [EN6].
> In Alpe d’Huez, ride up to the top of the resort, to the «Rond point des Pistes» roundabout and then onto the «Chemin Panoramique» that goes around the Grande Sure.
> Follow the panoramic path to a viewpoint table, where you can take a minute to admire the view, before switching into descent mode.
> Set off into the Combe du Bras, following the path straight down into the forest (not going up to the right). The upper part of the Combe du Bras features rather slippery soil bends. Lower down, the terrain becomes stony and more technical.
> This path brings you down to the Huez – Villard-Reculas tarmac road, which you take to the right for 3km to Villard-Reculas. The «Pas de la Confession» road daringly overhangs the entire Le Bourg-d’Oisans plain with superb viewpoints. Ride through Villard-Reculas. When you get to a car park, take the grassy path at the end to the left.
> The path into the Forêt de l’Ours starts below the war memorial, in a field where there are sometimes livestock. Take care, as «speed bumps» have been installed as far as the beginning of the wood.
> Once in the woodland, the path is fast until a small footbridge. Just afterwards, go straight on at the switchback, following the signs [EN 6]. The first part has lovely banked switchbacks and then after a traverse, you get to the more technical section called ‘La Fontaine de l’Ours’.
> After this exciting section, you arrive directly in the Bourg-d’Oisans plain, close to the hamlet of Le Raffour. From here, you can either go straight on to Allemond, or turn left to Le Bourg-d’Oisans.
