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.

This stretch of road is nice and offers a beautiful view. Be careful on the descent and be ready to brake, there are a lot of herds.

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.
