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.

We tried the Arc'Aïk Battle for our fun day: it's awesome! Definitely worth doing! The refreshments offered by the organizers were a big plus (the EcoCUPs are very beautiful!).
