Luz-Ardiden is well-known for hosting several mountain stage finishes of the Tour de France. The climb begins in the town of Luz-St-Sauveur and is fairly constant 7.2% through its entire length. Not overwhelmingly challenging by itself, it's a fun climb with numerous switchbacks all the way up to the ski area, which offers soaring eagle's-eye views of the town and valley of Luz-St-Sauveur. If you make the climb, you'll be rewarded with a swooping descent on smooth pavement with well-banked curves. Although this climb is too short to fill up a day of cycling on its own, I love itand its descentso much that I regularly include it in several of my routes.
