Key Largo Undersea Park | 51 Shoreland Drive

Key Largo FL 33037 | 305.451.2353

Located in the lagoon at Key Largo Undersea Park, Jules' is the world's first underwater hotel! In addition to overnight stays in the Lodge, 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.

The entire structure of Jules' Undersea Lodge is underwater, sitting up on legs approximately five feet off the bottom of the protected lagoon. The Lodge is filled with compressed air, which prevents the water from rising and flooding the rooms.

A five by seven foot "moon pool" entrance in the floor of the building makes entering the hotel much like surfacing through a small swimming pool. Divers find themselves in the wet room, the center of three compartments that make up the underwater living quarters. The wet room, as the name implies, is where divers leave their gear, enjoy a quick hot shower and towel-off before entering the rest of the living area.

Designed for comfort, the air conditioned living space has two private bed rooms and a common room. The eight by twenty foot common room is a multi-purpose room providing the galley, dining and entertainment areas. Each of the bedrooms and the common room is equipped with telephone, intercom, VCR/DVD and our latest addition of the, "I Home", so you can enjoy your own choice of music from home. But the main focus of attention is the big 42 inch round window that graces each room. "Waking up to view a pair of angelfish looking in your bedroom window is a moment you'll never forget"

Jules’ Undersea Lodge
is happy to announce the reopening of our world famous lodge.

Jules’ Undersea Luxury Package:

Jules’ guests will check-in at the front office and meet your Mission Director.  After a quick bit of paperwork and giving us your pizza order, you will have a top side orientation tour with your M.D.   You will then prepare your personal items for transport and gear will be issued.  Since we have WiFi we are happy to take down your cell phone or tablet to the lodge.  It’s fun to zoom and share your experience with family and friends.  Those who are certified divers will be able to dive the lagoon and then meet the M.D. inside the lodge where you’ll be introduced to our communication system and safety protocol.

The lodge is stocked with plenty of water, soda and ice tea.  Snacks are down there too.  (Please inform us of any allergies when you make your reservation.)
