Location: Okpo City, Geoje Island, South Korea
Years in operation: ?-1999
Creepy factor: 9
While we don't know much about the history of Okpo Land, a seriously foreboding abandoned fun park perched atop a hill on South Korea's tiny Geoje Island, we do know this: The park was shut down in 1999 after a number of fatal accidents, the last when a young girl tragically fell to her death from a ride. Immediately after that incident, the owner of the park disappeared and was never heard from again. Although Okpo Land has the dread-inducing looks and disturbing back-story seemingly plucked from a K-Horror film, that hasn't stopped hordes of fearless urban explorers from making a pilgrimage (this guy even spent the night).
