Have you ever explored the Ruhr from the water... No? Then off to Mülheim an der Ruhr! Book a "Green Fleet" pedal boat there and explore the area - up the Ruhr from Mülheim to Essen. You pass pretty old towns and end at Baldeneysee, which offers a nice way to slow down. You can rent houseboats with three or four berths or choose the Vitesse houseboat, which offers five berths. But be careful: The houseboat can only be driven with pure muscle power! So nothing with just sunbathing and looking stupid. Trample in the fresh air and enjoy the view of the countryside!
