Altstadthafen Berlin-Spandau

Set along the Havel in historic Spandau, this marina lets you get out on the water whether or not you have a boating licence — you can rent everything from rowboats and pedal boats to motorboats. It's a relaxed, unpretentious spot with the cobblestoned Altstadt just a short walk away, so you can easily pair a few hours on the river with lunch or a wander through one of Berlin's oldest neighbourhoods.
