Meet at the small car park in the village of Barberine.
This village is located 0.7km from the French-Swiss border on the D1506 coming from Chamonix.
(S/E) Go up the only street in the village on the left until you reach the bend leading to the EDF cable car. Take the path opposite, which climbs steeply into the forest, pass under a high-voltage power line and continue climbing, keeping to the right until you reach the junction for the Barberine waterfall.
(1) Leave the path on the right for the waterfall and continue climbing to a moraine valley and then into the forest. After a few very steep hairpin bends, you will begin the final climb to the Col du Passet.
(2) Leave the path climbing to the left and join the road coming from the Lac d'Emosson dam. Take this road on the left, first running alongside Lac d'Emosson for 1.7 km, then climbing for 2 km up the side of the Gorge du Vieux to the right of the Lac du Vieux Emosson dam. This road may also be partially snow-covered depending on the year, and passing through the two tunnels can then be "tricky".
(3) Take the path (not always very visible) to the right of the dam and walk along the northern edge of the lake. This path may disappear under patches of snow depending on the season, and may be between 20 and 50 metres from the water's edge depending on the year and the height of the lake. Follow this path along the lake to the southern tip.
(4) Continue along this path, heading due south towards Pointes à Corbeaux and Pointe de la Terrasse.
(5) Head southeast towards Col de la Terrasse and climb up to the Dinosaurs site (huge grey slabs surrounded by barriers below Col de la Terrasse).
(6) Begin descending northeast towards a small pass where snowfields are often present until you reach the junction for the climb to Col de la Terrasse.
(7) Continue straight ahead. The unmarked but well-marked trail is easy to follow and quickly descends into a gorge below the Veudale peak on the left and the Barberine mountain range on the right. Follow this gorge downhill, along the small Veudale stream, until you reach the heights of Lake Emosson.
(8) Leave the stream and continue along the path that runs alongside the dam road until you reach the Col du Passet.
At thethree-way junction, take the path on the right, which climbs steeply and then runs along the French side of the Barberine mountain to the Loriaz mountain pastures and chalets.
(9) Cross the chalets, take the path on the left after the last chalet and descend to the Croix de Loriaz.
(10) Leave the main path that descends to the right and descend to the left. Keep left at the next two crossroads through the forest until you reach the next crossroads.
(11) Go straight ahead and continue downhill through the forest until you reach the heights of the hamlet of La Villaz. Go down the road through the hamlet to the first bend. In the middle of the bend, take the path going up to the left into the forest and then follow it downhill, keeping to the right until you reach the third fork.
(12) Turn left and continue downhill through the forest, keeping to the right until you come out of the forest above the village of Barberine.
(13) Turn left and descend to the village of Barberine and then to the car park (S/E).
