A nice long climb that's not too steep (max. 8%), on a very quiet road. The asphalt is of good quality.

fairly easy pass allows you to go from one valley to another. Be careful of the gravel on the descent to Laborel

The climbs were tough, it's a shame there is no pass sign at the top. But there are great views of the mountains.
