Disney's Discovery Island, Bay Lake, Florida, USA

Disney opened a lush, green zoological park on the island, which housed many exotic animals. However, somehow the attraction never worked out and closed in 1999, when Disney moved the animals to the new Animal Kingdom. The buildings are crumbling and gradually being overgrown by greenery and the island is strictly off-limits. However, many intrepid adventurers have journeyed out to the abandoned resort, leading Disney to threaten to ban anyone trespassing from any Disney resort.
