Nice village, especially the starting point for beautiful bike rides. And then stop by the grocery store for a homemade apple tart, the best I've ever eaten!

The start begins strong, it sets the tone: a climb with a nice slope, but not extreme either!

Le plateau de Beille is very beautiful in the summer. While in winter it's a ski resort that didn't seem exceptional to me, in summer the cross-country ski trails become gravel paths, and in fact, this plateau is top to explore!
