An ideal loop to try your hand at trail running along the Biaysse as you take to the heights above Freissinières valley.

From the Valley Centre ("Maison de la Vallée") go down into the meadow and cross the Biaysse. Follow the track along the right-hand bank of the river which runs past the adventure park ("Parc d'Aventure").

Cross back over the Biaysse and turn right onto the road. 100 metres further on, fork left towards the hamlet of “Le Plan” and go through the hamlet. 
Take the track which runs uphill to the right and continue on this path which runs across some screes.
Take the path on the right which leads back down to the D38.
At the intersection with the D38, turn right and after 70 metres go left to cross the bridge. After this bridge, head left and carry on along this path which runs along the edge of a campsite, the Camping des Allouviers. 
Turn right. Carry on along the path which eventually runs alongside the Biaysse and past the Adventure Park again. This brings you back to the Valley Centre ("Maison de la Vallée").
