Plan Col is a mountain pasture located at the top of the pass, connecting Moulin Vieux (Roizonne valley) and Ornon (Malsanne valley).
During this hike, follow the Vaunoire stream and observe how the flora adapts to changes in altitude: starting in the forest, you’ll gradually leave the woods behind for alpine pastures at nearly 1900 meters.

Drive up to the parking area at the end of the road that leads into the Vaunoire valley from Moulin Vieux. From there, follow the wide and gently sloping path that continues toward the end of the valley. Keep going on this trail, cross the stream coming from the Taillefer, and begin climbing through the beech forest via well-marked switchbacks. After an initial steep section, reach a small flat area, often still covered in snow late into the season. After crossing the stream again (via a bridge), a short series of switchbacks leads you into a broad basin. Past a small rise, the valley opens up slightly; continue on the trail and ford the stream. Climb diagonally up the slope of Plan Col, which you’ll reach after a final switchback. Use the same route for the descent.

Caution!
You are in a protected natural area. Please stay on marked trails, keep your dog on a leash, do not light fires, and carry your waste back with you or dispose of it in the nearest bins. Respecting and preserving this special environment is essential!
