Reviews Summary

Guests rave about the unparalleled, unique experience of sleeping underwater and the incredible marine life visible from the lodge. The novelty of the underwater entry and dining options are consistently praised, making it a highly rewarding and educational adventure. Some minor drawbacks include the limited space and the need for scuba certification, which can be a barrier for some.

"I recently passed through here on my little skiff to check out the place. My family owned this MARINA from 1970 to 75. It was called paradise Isle Marina back then. They have done an amazing job to this place. It looks great. I can’t give any information about the underwater Lodge. No one was around to get information on it, but here are some before pictures back from the 70s."

Wayde Moore

"Nothing cooler than the science behind living in an ambient pressure habitat under the sea. This is the coolest experince I've had under water. I plan to return, for sure! Such a rewarding educational experience. Worth the money!"

Eddie Bryant

"Had the opportunity to dive at Jules lagoon to complete my sons open water check out dives. The staff couldn’t be more accommodating and friendly. The equipment we rented was fantastic and we were able to get in the water very quickly because the staff was so organized. If your in the keys check out this spot they have an underwater hotel suite also that blew me away…"

In-depth insights and expert knowledge

The Science of Submersion

Jules' Undersea Lodge is more than just a hotel; it's a scientific habitat. It operates at ambient pressure, meaning the pressure inside the lodge is the same as the pressure of the surrounding water. This is a key difference from traditional submarines or pressurized habitats. This unique environment allows for extended stays without the physiological challenges of significant pressure changes. Instagram+1

This principle of ambient pressure living has been explored in various marine research projects. The lodge itself was originally an experimental marine laboratory before being converted into a unique accommodation. This history underscores its significance in the exploration of underwater living. Instagram+1

Recent research, like the 'Project Neptune 100' experiment conducted by Dr. Joseph Dituri, has further highlighted the potential of living in such an environment for extended periods. These studies aim to understand the effects of prolonged submersion on the human body, potentially paving the way for future underwater exploration and habitation. Instagram+3

This introductory experience provides the necessary training and a guided dive to the lodge, ensuring everyone can experience the unique entry. It's a fantastic way to get certified and immediately use your new skills in an extraordinary setting. Reddit

Once you've completed your dive, you'll enter the lodge through an airlock. Inside, you'll find a comfortable, well-equipped habitat ready to welcome you for your underwater stay. The process is designed to be safe, exciting, and memorable. Reddit
