Welcome to Key Largo Undersea Park, the home of Jules Undersea Lodge, the world's only underwater hotel!

The Park offers a great SCUBA training location in its Lagoon, with a depth of up to 30' in a protected setting. Individuals can get Open Water certified here, do a Discover SCUBA Diving course, or just dive around in the lagoon. SCUBA Instructors can take their students here to go over confined OR open water skills!

Lunch PADI Specialities


After you're done with your SCUBA skills, or if you are already SCUBA certified, you can visit Jules' Undersea Lodge for three hours or an overnight! Have lunch in the Lodge, do a three hour Mini Adventure, or sleep underwater! Distinctive PADI Specialities are available for overnight guests. Check out our video!
