Fähre F12 Grünau

Nice start for a hike. And 20 minutes on Sunday is also ok, especially since you can already on board before.

The BVG ferry commutes throughout the year between Grünau and the Köpenicker district Wendenschloß. Weekdays from 06:00 to 20:00 clock every 20 minutes. At peak times early and even every 10 minutes.
At the weekend, the ferry starts a little later. Saturdays 7:30 in the summer and 8:30 in the winter. Sundays all year round 08:30.

Almost silent deceleration when driving over the Dahme.
