While the boat tours typically last an hour or two, the boats run every 15 minutes (30 minutes in winter) throughout the day, allowing travelers to hop on and hop off at designated spots with no additional cost. These stations are close to some of Berlin's most beloved sights, including the Berlin Wall historical site at the House at Checkpoint Charlie, the Berliner Dom, the Brandenburg Gate, the famous Unter den Linden boulevard, and the Kaufhaus des Westens department store.
