Fantasy Fest is a ten day Halloween celebration that commences on a Friday night with the Coronation Ball, where the King and Queen on Fantasy Fest are Crowned. Fantasy Fest was conceived as a way to boost tourism in Key West. It is now the biggest event of the year, bringing some 50,000 revelers to Duval Street for the Saturday Night Parade. Much like Mardi Gras, Fantasy Fest is an Adult Event, including many Costumes, Body Painting, and Floats. Best of all, AIDS Help, The Florida Keys Children's Shelter, and other Non Profit Organizations, benefit from this event.
