Peenemünde Haupthafen

You're docking at the far north-western tip of Usedom, where the Peenestrom opens out toward the Baltic — as far as the island goes. The marina puts you right next to Peenemünde's famous historical site, the WWII rocket development facility turned museum, so there's plenty to explore once you're tied up. It's a genuinely unusual mix of remote island-end atmosphere and serious maritime history, all in one stop.
