A boat cruise on Lake Constance is one of the essential experiences of Konstanz, gliding across the shimmering water past the Flower Island of Mainau, the historic town of Meersburg and the shores of Germany, Switzerland and Austria. Regular ferries and excursion boats depart from the harbour for scenic trips of varying lengths. Watching the lakeside towns, vineyards and, on clear days, the distant Alps drift by from the deck is a relaxing and beautiful way to enjoy the region.
