The lake itself is a prime attraction, with boat trips available to nearby Switzerland and Germany. Don't forget to bring along your passport. The Bodensee White Fleet ferries offer several trip options. You can travel to the "flower isle" of Mainau or make a crossing to Konstanz, Germany, with stops at Lindau, Friedrichshafen, and Meersburg. The longest round-trip excursion is the Drei-Länder Rundfahrt, which includes stops in Germany and Switzerland. The ferries have
different operating schedules, but most run only in the summer months. The Mainau excursion runs from May to mid-September.
