Jules Undersea Lodge

Jules' Undersea Lodge is the original and still the only place to book an underwater vacation - and to experience life as an "aquanaut," the term applied to divers who stay down for more than a day, sort of like pilots and space crews get to be called astronauts.

Jules' is the world's only underwater hotel, which offers SCUBA training in its lagoon. There is a catch - you have to dive 21 feet below the sea to get there!
