I came here during a bikepacking trip and haven't regretted it. Beautifully situated, clean, and in warm weather, the small lake is a great place to cool off. The small grocery store in the cupboard with the essentials for emergencies is great and makes you smile. Search for campinglesizoard when looking for the site's website.

Very pretty village which is worth a stroll to discover the old buildings including a communal oven (still in operation), a fruit store, a Protestant temple, a wash house, the church, etc.

About the Col des Ayes, I wrote in an old notebook: “At 2,477 meters above sea level, I reach the Col des Ayes which separates Briançon where I will go tomorrow and Brunissard, a small resort left behind at noon. Despite a wind worthy of the gusts of Brittany, I take a break to observe the mountain. Eyes riveted on the compass, I quickly analyze the path traveled over the past two days. I recognize the massif on which rests the Saint-Simon Chapel where I spent the last night. But above all, I observe about thirty kilometers away the sumptuous Bric de Rubren and its 3,340 meters, proudly climbed two days earlier.
