A gentle, narrow climb. From the west, the gradient is consistently high, with no respite. The asphalt is in good condition on both sides, making it easy to descend as well.

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.
