Sometimes the best way to describe something is by saying what it isn't. Dolphin Cay isn't an aquarium, it's not an entertainment facility, and it doesn't stage marine shows. Opened in 2007 in response to a need to provide a safe haven for 17 stranded dolphins whose home was destroyed by Hurricane Katrina, Dolphin Cay is one of the world's largest open-air, man-made marine mammal habitats. Located on the west side of the Atlantis, Paradise Island property, the 14-acre environment includes an 11-acre lagoon complete with coves and sandy beaches, 7 connected "residential" pools, a state-of-the-art education center, an animal rescue-rehabilitation hospital, an animal pharmacy, a quarantine, and a separate sea lion center.
