Situated off the shore of Disney’s Wilderness Lodge Resort, the Treasure Island Nature Preserve became Discovery Island on April 8, 1977 and eventually closed on April 8, 1999. The 11-and-a-half-acre paradise was home to exotic birds and animals. Originally, the island was themed to the film Treasure Island and a wrecked ship inspired from the film was seen on the shore. It featured one of the largest aviaries in the world and giant tortoises.
