The passage of the landslide is done with portage (SPD wedges) the ascent at the end of the landslide on the Mortier tunnel side is deteriorating (drought/crowd) the staircase kindly built by local lovers is badly damaged. Such a shame that this closed road is not rehabilitated at least for the passage of 2 wheels ... it would be enough, as in Italy, to put up a sign stating that this access is dangerous and that its passage is at our own risk 🤷🏻♀️
