This great natural bathing area was my goal for the day! At the village of Diano Roncagli I searched intensively for the marked spot, but it was in the middle of the (even on foot!) inaccessible wilderness on the mountainside above the steep road up to the village. Shortly before the village I discovered a hiking trail that led up the mountain slope to the right of the road at an acute angle. After about 200 m, I finally reached a creek that tumbled down through a small gorge in steps, either by pushing my bike or on foot. At this point there were also the small pools of water in two of the photos, in which I could refresh myself. I then walked a little further along the path into the small, increasingly steep gorge, which was very impressive due to the great vegetation around the stream with tiered pools. There was no further path on the stream itself - everything was too steep and overgrown. The path itself then led out of the gorge steeply up the mountainside.
The large pool in the photos in front of the rock face with a waterfall and men bathing was nowhere to be found. Unfortunately, the path marking on Komoot is inaccurate, the creek is not marked. In any case, it is worth the effort to visit this great place. I've corrected the positioning of this HL so that it now marks exactly where the pools of water are.
I would be interested to know if anyone can find the "Bagno ristoratore sotto cascatella"!
