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.

Nice climb, few cars, be careful on the descent, the asphalt is smooth but the grip is not the best, moreover some bends close. A great champion fell here during a TdF.
