The Pic Chaussy peak at 2351m is one of the most treasured summits in the Vaudoise Alps. It’s 360° panorama provides the most incredible views. This ascent is also one of the more popular as much for its easy access as for its route which takes you to Lake Lioson and the Small Lakes.
From the start, located at the corner of the Tourist Office building in the centre of Les Mosses, take the path up through the fields. At the first crossroads (road), turn left and follow the road.
At the end of the level stretch, the road bends to the right. Follow this road until you reach a second crossroads. Continue straight ahead, passing to the left of the Pully colony. Continue straight along the road. You will pass the Lioson d'En bas mountain pasture. If you're an early riser, you can even take the opportunity to watch the cheese being made (from 9.30am to 10.30am). Follow the path upwards for 5 minutes.
At the fork in the road, turn left and continue uphill to the lake, which you reach in 40 minutes.
The restaurant on Lac Lioson and its terrace offer a well-deserved break. Continue your ascent by skirting the lake on the right for 5 minutes, then begin the ascent of Pic Chaussy. After 35 minutes, you'll reach the Col de la Rouge.
From here, continue your ascent for another 30 minutes to reach the summit of Pic Chaussy. There is a small picnic area where you can linger and enjoy the panorama: Glacier des Diablerets, Gummfluh, Dents du Midi and even Mont-Blanc.
To get back down, retrace your steps to the Col de la Rouge. Then continue left towards the Petits-Lacs. This rocky region is home to marmots and ibex.
Once you reach the Petits-Lacs, continue downhill past the mountain pasture to reach the Alpage du Lioson d'En-Bas.
Take the small path on the left (through a gate) and follow it to the top of the village (first chalets). Return to the centre by following the road back down towards the resort.
Option: You can shorten the route by not making the full ascent of Pic Chaussy. In this case, at the Col de la Rouge, start straight down to the Petits-Lacs.
