This approximately 32-kilometer tour combines the beautiful green nature of the water-rich environment of Treptow-Köpenick with many cultural highlights that can be discovered by bike particularly well.Your journey begins at the S-Bahn station Grünau, the district known for its regatta course. But before you can take a look at it from the ferry, the route makes a small detour to the garden city Falkenberg. The housing estate in Berlin's Bohnsdorf district was designed by architect Bruno Taut in 1912, modeled after English terraced houses. Even today, here is a small idyll and also a colorful eyewitness - so remarkable that the settlement is now part of the UNESCO World Heritage.Now you cross the Dahme by ferry and follow it southwards at the foot of the Müggelberge. Another short ferry ride and you reach Schmöckwitz, a former fishing village that still benefits from its position in the water today. Not by fishing, but as a popular recreational destination. Above all, the nearby Krossinsee, the Zeuthener Lake and the campsites located there attract many tourists and recreation seekers.Along the Seddinsees you now cycle to Gosen. The small village has an interesting past. Founded in the 18th century as a spinner's village to supply regional wool factories, the area developed into an important shipping location in the 19th century - so important that even a school for skippers was founded here. At the time of the GDR was also trained here - but not in shipping. In Gosen was the former training center of the GDR state security for foreign agents. In the Heimatstube Gosen you can always learn everything about the region's past on Sundays from 3 to 6 pm.Finally, you cycle through Berlin's easternmost district Rahnsdorf with its settlements Hessenwinkel and New Venice. Here is worth a short detour to Dämeritzsee before a very special ferry ride is waiting for you: The F24 between Rahnsdorf and Müggelheim is the smallest ferry in Berlin and is powered by oars. From here it is not far to the finish line of the tour: From the S-Bahn station Rahnsdorf you can comfortably and quickly be brought back in all directions of Berlin.
