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!

The Château de Foix impressively thrones on a rock above the town of the same name in the French Pyrenees. The medieval castle with its three distinctive towers was once the seat of the powerful Counts of Foix. Today, it houses a museum of regional history and offers a magnificent view of the old town and the surrounding mountain landscape.

It is a MUST in the Pyrenees, without a doubt, that should be included in any route that crosses the Pyrenees from side to side. Either of its slopes 2 is spectacular and tough. The views from its summit are wonderful, feeling the wild side of the Pyrenees. Of course, once at the summit of this pass... you have to descend to the Étang de Lers and enjoy a peaceful rest on the shores of the lake. It is a pass that has been part of the Tour de France route on several occasions, although always far from the finish line. The first professional rider to crest it in the lead was the unforgettable Marco Pantani in 1995.
