Col du Tourmalet

From Luz-Saint-Sauveur: about 19 km at 7.4%, summit 2,115 m, road closed roughly November to May The Tour has crossed the Tourmalet more often than any other climb, close to 90 times by recent counts, since it first sent riders over in 1910. That makes it the Pyrenean climb to ride if you only do one. The western side from Luz-Saint-Sauveur is the steeper test, with ramps above 10%; the eastern side from Campan is longer at a gentler 6% average and passes through the ski station of La Mongie. Snow keeps the road shut through the winter, so aim for summer rather than the first weeks after it reopens.
