One of our favorite summits in France, you can visit the winery and then hike up the road to the chapel and play radio! You can even stay overnight in accommodations at the winery. The hike is all of 1km with about 90m of rise. At the chapel there's a bench and some shade - a perfect spot to activate after wine!
It's perhaps easiest to find the summit by finding the winery: Chemin Notre Dame des Anges, 84570 Mormoiron. That's about an hour east of Avigion.
