Tall Stacks was first held as part of Cincinnati's Bicentennial year in 1988. That first Tall Stacks welcomed 14 riverboats and over 700,000 people to the city's riverbanks for three days in October. Tall Stacks launched a legacy of pride in Cincinnati's rich river history and rekindled the nation's love affair with the steamboat. Held approximately every four years, this event has grown to span five full days of wonderful riverboats with cruises, tours and races, as well as music and entertainment.
