Jazzland/Six Flags New Orleans
Location: New Orleans, Louisiana
Years in operation: 2000-2005
Creepy factor: 9
When Hurricane Katrina struck the Gulf Coast in 2005, park operators at Six Flags New Orleans were in the planning stages of opening a water park. Well, they got one. Severely damaged by Katrina's devastating floodwaters and forced to close, Six Flags New Orleans, which originally opened as Jazzland in 2000, remains in an arrested state of decay to this day and is perhaps more famous now — thanks in part to numerous camera-wielding urban explorers — than it was when in operation. Home to still-standing Cajun-themed attractions like the Zydeco Scream and the Muskrat Scrambler, the future of the property, now owned by the city of New Orleans, is unclear.
