Under the impression that there was a bridge here, my partner and I cycled the climb and descend to this river valley in order to cross from south to north. After crossing the smaller river multiple times to get our bikes and luggage across, we came to the big one – completely uncrossable due to high amounts of snowmelt in the month of July. There's no bridges in this valley (2022) and you should only go here once they have actually been put in place.
