An American legend. An authentic sternwheeler. Named after the beloved riverboat-era author Samuel Clemens, the Mark Twain is classic, captivating and comfortable. The first deck is climate-controlled for year-round comfort with large panoramic windows. The second deck is open-air, giving you an unobstructed view of Cincinnati's beautiful skyline and Kentucky's graceful rolling hills. See below for a view of the Mark Twain's floor plan layout.
