Location: D526 Entraigues to Le Bourg-d’Oisans (18 miles)
Col d’Ornon is located on the D526 between Entraigues and Le Bourg-d’Oisans. To get to Entraigues pick one of the half a dozen or more roads that you can take off the N85 Route Napoleon between Grenoble to Gap and from here it’s a really nice 25 mile ride all the way to Le Bourg-d’Oisans.
The run up to the top from Entraigues is good although it doesn’t look or feel much like a pass road. The run down the other side is a much more impressive affair though and far more pass like. After leaving the plateau at the top there are a series of hairpins that mark the start of descent proper and from this point on the road begins to narrow as it drops down the Torrent de la Lignarre Valley, through forests and villages, all the way to the bottom where the pass road meets the D1091 and the right turn to Le Bourg-d’Oisans.
An enjoyable pass to ride, not the best of surfaces, but quiet with some great scenery. There’s a nice auberge at the top where you can stop for a coffee or a bite to eat if you can’t wait until you get to Le Bourg-d’Oisans .
