The Lagoon

The Jules lagoon offers something for a snorkeler, SCUBA diver candidate, SCUBA professional, or recreational diver! Things you can find in the Jules lagoon are as follows: a marine archaeology exhibit, the MarineLab underwater research and education habitat, and Jules’ Undersea Lodge, which is the first and only underwater hotel in the world.

The Lagoon is only 30 ft deep and although it is open water it is sheltered making this a beginner friendly dive site. Dives must all be planned and scheduled by the team over at Jules. We here at MDS can make the scheduling for you however this dive site is not always a guaranteed possible location. When in the lagoon you might spot Sea Horses, Snapper, Parrot Fish, Barracuda, Sergeant Majors, Blue Tangs and if you are very lucky Manatees.

All pricing information for Jules Undersea lodge can be found on their website linked above. We only include the price of having a scuba instructor with you!

The Lodge

Jules Undersea Lodge is the ONLY underwater hotel that’s only entrance is via scuba diving.

Inside the lodging you start off by entering a room with bathrooms, gear storage, towels to dry off, and showers. Its very important to dry yourself off as much as possible when entering in order to protect the interior of the lodge. On the door to your right you will find the beds and sleeping area. On the door to your left is where you can find the kitchen, dinning, and living room.

The lodge is equipped with waters, sodas, and snacks but also has its very own pizza delivery service!

You also have the option with Jules to book the aquanaut package which gives you a specialty Padi certification. Inside you will also have an intercom system with the team on the surface for safety at all times!

Pizza Lunch In

Our team here at McManus Diving Services was very honored to have been able to be a part of the first ever Jules Undersea Lodge pizza lunch in. Which is a great option for those who cant stay overnight but would still like to explore inside the lodge.

A member from Jules will brief you before you get ready to dive and take everyone’s orders as well as any items you would like to have delivered down there that cant get wet such as a cell phone. After that its time to gear up and you can spend some time diving around in the lagoon. A Jules member will then take you inside the lodge and go over another short briefing on the rules and aspects of the lodge. After this you are free to explore until you receive your underwater pizza delivery. MDS would like to give a special shoutout to the awesome Captain Sharky and the team over at Jules for an amazing time and truly once in a lifetime experience.
