In response to CamilleD, a useful link: https://climbfinder.com/fr/montees/col-de-marocaz-arbin The % indicated on the terminals correspond to the average percentage over the km following the terminal. It seems that this nice pass deserves the % indicated. Pass covered on a Sunday afternoon, little attendance, mainly motorbikes.
