Finish the tour above the waterfall because it is not visible! And enjoy the tunnels upstream (this being prohibited from the waterfall; landslides possible... bring a torch!)

We couldn't find this waterfall. It's signposted at the monastery, but where it's marked on the map, there's no waterfall like the one in the photo. The stream valley in the enchanted forest is very beautiful, but there's no waterfall. We walked more than 1 km beyond this point (despite the sign "Private property, no entry"), but still didn't find a waterfall. You might have to go much further than indicated on the map. On Google Maps, the waterfall is marked higher in German, closer to where the hiking trail ends in a dead end.

This spot didn't impress me: "blue lake" is an exaggeration, it's a very small reservoir... lots of people on the banks too.

The Mélogne mill, built in 1495, operated until the First World War, when a fire just after the last war permanently destroyed it. https://www.hautbugey-tourisme.com/patrimoine-naturel/cascade-de-melogne/
