A roughly 300-year-old water-powered washing machine. For 1 KM, you can get an explanation of how it works in English. According to the owner, it's still used by villagers today. There's a second one near the small waterfall.

A fairly rough gravel section with a short uphill, followed by a long, steep descent. We had fun on our touring bikes.

Very beautiful waterfall! 🤩🤩📷 Here, too, you drive a few kilometers on a gravel road. This can be managed by motorbike with good road tires when it's dry. At the end there is a parking lot with the entrance booth. We paid the equivalent of €1.50 per person and then hiked up the path to the waterfall. It was worth it!!! Wonderful nature!!! You should definitely visit. The crowds were limited. No long queues in front of the entrance booth or at the photo bridge.
