Floating along on the water and discovering the beautiful green banks of the Spree and Rummelsburger See - The Ahoi Ostkreuz is an ideal starting point for this. The kayak, paddle boat and pedal boat rental agency has everything you need in the summer months. You can also rent SUP boards here. From here you can explore Treptower Park and Plänterwald on the water or take a trip into the city centre. Up to the Oberbaumbrücke, navigation on the Spree is also permitted without a motor. Incidentally, the environment is very important to the boat hire company: Every year the CLEANUP REGATTA takes place, during which rubbish is collected from the Spree and the bay.
