Travel to Heligoland on the high-speed catamaran "Halunder Jet"! This absolute highlight is the most beautiful and easiest way to reach Germany's only high seas island. On Heligoland, we even sail directly into the harbor, so there is no need to disembark. This makes a trip from Hamburg, Brunsbüttel and Cuxhaven to Germany's only high seas island, Heligoland, a short hop.
