One of the most heart-pumping stretches of the Tour de France is always the 21 hairpin curves at L'Alpe d'Huez. Doesn’t sound so hard? They bike up the mountain. Every summer, hundreds of amateur cyclists flock to this resort in the French Alps and make the same climb. It’s more famous as a warm-weather destination, but L'Alpe d'Huez is also one of Europe’s top ski destinations. The nearby slopes appeal to beginners, but they get more challenging a bit farther away. More experienced skiers and snowboarders can literally travel for miles on some of the most challenging runs. And there are plenty of off-piste areas, too.
