The weir seen from the bridge has four openings closed with hydraulically operated flaps. Next to the weir are the fish ladder and the boat alley. In the case of large floods, the entire system is flooded. In 2011, a hydroelectric power station was built on the right side of the weir. The entire Ruhr flows through the power plant and enables electricity to be generated by around 3.6 million kWh annually.

The only Ruhr ferry. There is no fare, just a donation box. You can even use PayPal. Is a great project. So don't be stingy.

It's nice that everything is separated here, everyone has their own way, speaks for pedestrians, inline skaters and cyclists, of course, there are always people who don't stick to it, but otherwise you can drive there great, the paths are super easy to drive when you do a lap around the Kemnader turns.

The Hardenstein Ruhr Valley Ferry also crosses the Ruhr at the castle ruins of the same name. The crossing takes only a few minutes, but is still a highlight for any cyclist. The crossing is technically free. However, there are money boxes on the ferry itself, and you can deposit some change. The motto: Pay what it's worth to you.
