5. Have dolphins propel you across a lagoon in the Bahamas At Dolphin Cay on the Atlantis Resort property, you can interact with these loveable marine mammals. Led by marine biologists, participants have the opportunity to stay dry (relatively) and be “trainer” for a day, giving the dolphins their signals and rewarding good behavior with fish. For a more personal experience, jump in the water and hold tight as the dolphins carry you across the lagoon. Dolphin Cay is a member of the Alliance of Marine Mammal Parks and Aquariums and strictly adheres to its guidelines for mammal health and welfare.
