A legendary climb up Hautacam. Look for the sign for the climb to Tramassel to see the other side of the valley. It's not much further or steeper, and it's worth it.

Quite a difficult climb but it's quite easy to do (you might have to push the bike if you're not in good shape). Very pleasant descent, pleasant road and beautiful view.
