Follow the Route des Orres (D40), pass through the village of Baratier, then look out for the road on the right heading towards Le Camping Les Airelles. Pass the campsite and, at the next junction, ignore Valubaye and turn left. Continue along the road and, at the next junction in a hairpin bend, turn left onto the track and follow it to its end. Park in the car park at the foot of the power station.
(S/E) Look out for the path on the right that climbs uphill, follow it, and pass in front of thefirst dam. Take a moment to look at the dam and search for the cache. Continue along the path and discover the caches, passing under a penstock to reach a footbridge.
(1) Before crossing it, continue straight on to see another dam, then retrace your steps, cross the footbridge and turn right. Climb a little, then take the path on the left, and at the crossroads turn left onto the downhill track. Continue until you cross a wooden bridge. After the bridge, take the path on the left, still going downhill, and follow it to the penstock.
(2) Leave the track and take the path on the left. Descend to the EDF building, staying on the track the whole time. You will reach a final dam. Take the track on the left which crosses the Torrent des Vachères. Then take the track on the left which leads back to the power station car park (S/E).
