Boat trips across the Havel are our recommendation for a relaxing boat trip with swimming and barbecue. Here you can anchor and go for a swim. The water is much cleaner than in the inner area of the Spree. You can expect beautiful bays, beaches and islands.
A boat trip across the Havel and Wannsee starts either at Pichelssee or Stößensee. Both harbors are located just behind the Berlin Olympic Stadium and are very easy to reach by public transportation (BVG). The bus M49 runs 24 hours a day and stops directly at the respective pier of the boats. Renting a boat in Spandau is very uncomplicated and recommendable.
As soon as you leave the harbor, your boat trip on the Havel begins. The trip to Wannsee takes between one hour and ninety minutes, depending on the boat and speed. For a tour around the Peacock Island you should plan another 45 minutes. It takes about 60 minutes by boat from Wannsee to Potsdam.
