At the top of Pic Chaussy, a mountain in the Bernese Alps, you'll overlook Les Diablerets in the canton of Vaud. It is amongst the top 4000 highest peaks in Switzerland.
You are able to ride a cable car up some of the way until you reach the Lison from below. You must then follow the road through the forest toward Lake Lioson. Along the lake shoreline you will come across The Chenau which is a northern slope. The slope will take you to the main ridge which is just 50 meter from the top.
