From the A90, take exit 38 and follow signs for Col de la Madeleine. Stop at the edge of the village of Celliers where the Ruisseau de Bridan is crossed, in a small car park beside the stream.
(S/E) Head down the road, re-enter Celliers and join a path just before the church.
(1) Follow this path to the left, where a sign points to the Logis des Fées. Walk above the village through a field and very quickly enter the forest; continue until you reach the Esserts crossroads
(2) Turn left, continue following signs for Logis des Fées at the next junction, and stay on the path on the right. Continue along a fairly flat track until you reach the avalanche barrier junction.
(3) Continue left, following signs for Logis des Fées and Lac de l’Arpettaz. Pass by an avalanche trigger device and numerous avalanche barriers. Zigzag through the hairpin bends to reach the road. Stay on the path and emerge at the Logis des Fées refuge.
(4) Follow the road uphill; initially tarmac, it turns into a track. Continue, pass three hairpin bends and, after about a hundred metres, reach the junction of a faint path.
(5) Turn right here, follow the track and you’ll reach Lac de l’Arpettaz.
(6) Continue left towards Lac Branlay to reach a fork at a place called Le Grand Plan.
(7) Turn right onto the ridge and, following a faint path, climb a series of small peaks to reach the one just before Pic de Lachat.
(8) Return to the Grand Plan crossroads by the same route.
(7) Turn right, continue on to the hut overlooking the lake, then head towards Lac de Branlay, where you will find the signpost: Lac Branlay.
(9) Walk around the lake. Back at the crossroads, turn right and continue the descent. You will arrive near the Chalet du Queigey, a shepherd’s hut.
(10) Continue on until you reach a crossroads.
(11) Follow the path downhill, which crosses the road five times, and keep heading towards Celliers to return to the car park beside the Ruisseau de Bridan (S/E).
