Jules’ Undersea Lodge

Guests can stay from three to 24 hours, or more! See our prerequisites information for more detals!We can also host your Special Event!

When guests visit Jules’ Undersea Lodge in Key Largo, Florida, they discover that the name is no marketing gimmick. Just to enter the Lodge, one must actually scuba dive 21 feet beneath the surface of the sea. Jules’ really is underwater. Diving through the tropical mangrove habitat of the Emerald Lagoon and approaching the world’s only underwater hotel is quite an experience. Even from the outside, Jules’ big 42 inch round windows cast a warm invitation to come in and stay a while, relax and get to know the underwater world that so few of us have even visited.

Entering through an opening in the bottom of the habitat, the feeling is much like discovering a secret underwater clubhouse. The cottage sized building isn’t short on creature comforts: hot showers, a well stocked kitchen (complete with refrigerator and microwave), books, an Amazon FireStick which offers music and movies on demand. And of course there are cozy beds, where guests snuggle up and watch the fish visit the windows of their favorite underwater “terrarium”. Jules’ Undersea Lodge manages to reach a perfect balance of relaxation and adventure.

Prerequisites: To get into Jules’ Undersea Lodge, you must be a certified SCUBA diver or take the Discover SCUBA course upon arrival. We accept all current agency certifications (PADI, NAUI, SSI, etc) but you must show proof of certification. If you arrive without a certification card, we must verify your certification with your agency. If we are not able to verify your certification, you will need to take the Discover SCUBA Diving course to continue.

If you are not a certified diver, you can take the Discover SCUBA Diving course for $115. This is not a full Scuba Diving certification, and you must be 12 years old to take the course.  Please note:  Jules’ does not recognize any resort course that you may have taken before you arrive at our facility.  The “Resort or Discover Scuba Diving” course is specific to the facility or resort you are established with at the time.  If you are NOT A FULLY CERTIFIED SCUBA DIVER you will have to take our Discover Scuba Diving course when you arrive.
