Tripadvisor’s approach to reviews
Before posting, each Tripadvisor review goes through an automated tracking system, which collects information, answering the following questions: how, what, where and when. If the system detects something that potentially contradicts our community guidelines, the review is not published.
When the system detects a problem, a review may be automatically rejected, sent to the reviewer for validation, or manually reviewed by our team of content specialists, who work 24/7 to maintain the quality of the reviews on our site.
Our team checks each review posted on the site disputed by our community as not meeting our community guidelines.

My husband and I just completed the Aquanaut Specialty Program at Jules Undersea Lodge and can’t recommend it enough. The program entails staying in the underwater habitat for 24 hours and completing three dives (entry to the habitat, exploration, and return to the surface.) Our mission director Camille looked after us throughout, guiding our dives, giving us lots of great information about the history and workings of the underwater habitat, and even delivering (still hot) pizzas in the evening of our stay! The entire experience was magical, from diving the lagoon and seeing the 17th century anchor, to lying in bed while hogfish swam past our porthole, to watching The Abyss five fathoms below the surface. Very few recreational divers will have the opportunity to reach full saturation, so for that reason alone, this was a bucket list item for us. Highly recommended. Thanks to Theresa, Julie, and everyone else at Jules Undersea Lodge for making our experience such a positive one!

Spending the night at Jules Undersea Lodge has been on my husband’s bucket list for a very long time. This adventure was everything we hoped for and more. We had excellent communication with the staff before we even arrived. They are all extremely friendly, organized and detail oriented. Daniel and Robert helped us with all of our equipment and were very patient. The lodge was well stocked with fruit, bagels, muffins and various snacks. The pizza/sub delivery was just too cool. We loved sleeping with the fish, but the highlight was seeing all the fish on our exit dive. We definitely recommend.

What a unique adventure. We had a great time. Everyone there was super friendly and took great care of us. We dove down to the lodge around lunch time and they had lunch waiting for us when we arrived. There were diving classes happening that same day so once we made it to the lodge we stayed because it was too murky to see anything if we ventured out again. Inside there was a kitchen/sitting area with a couch tables and TV. We watched TV all night. The team delivered pizza and salads to us that night by diving them down to us. Two bedrooms were on the opposite side with two bunk beds. Bottom bunk is big enough for 2. They can and helped us get ready to dive out the next morning around 8:00 am. No safety stop necessary. You just can't fly or dive again for 24 hours. It was 70 degrees inside the lodge. Some of the scuba class students swam past our bubble window while we were watching TV so that was cool. There is also a shower down there you can rinse off for the night.

This is the second time my husband and I have spent the night at Jules Undersea Lodge. We brought our 11 year old son this time. It is a fantastic and unique experience, highly recommended if you're looking for something out of the ordinary and a little adventurous.

When I tell people about this place, they tend to assume that it's some sort of large hotel complex - that is not at all true. A maximum of 6 people can stay in it at one time, but I imagine they probably wouldn't rent it out at the same time to people who didn't know each other - it would be pretty close for comfort if you had to spend the night here with strangers.

The "lodge" is actually a former underwater research habitat (La Chalupa) which has been converted into pretty comfortable, if not hugely spacious, overnight accommodations for divers. The only way to reach it is by diving into it, so you need to be SCUBA certified (or I believe they have an on-site resort course if you aren't certified). SCUBA gear is included in the price of the overnight stay. The habitat is pressurized to approximately 22 feet so you will be doing a saturation dive if you spend the night. Still, the depth is not excessive so there is no decompression needed on the way up. There's also an option to stay in the lodge for only a few hours and have lunch down there, but honestly I think the overnight stay can't be beat!

Access to the habitat is through a moon pool that leads into a "wet" room. This is where all the dive gear is stored. From this room you can access the shower, the marine head, and the two living compartments. The shower has surprisingly good water pressure, the water gets plenty hot, and they provide shampoo, conditioner, and soap. Before going into the living compartments you shower and dry off, so the rest of the habitat remains dry and salt-free. The wet room can get humid and fairly warm, but the rest of the areas are air conditioned and might even get a bit cold at times - bring a long-sleeved shirt or something if you get cold easily.

The rest of the habitat consists of two giant "tubes" - one contains two small bedrooms and one contains the living area. The bedrooms each have a double bed and a suspended single bunk, so six people could theoretically fit (that top bunk is pretty small though). Each bedroom has a porthole, a small sink, and a little bench in front of the porthole. The living area has a fridge, microwave, sink, two small tables, a bench by the porthole, and a TV/DVD player. The staff stocks the place with plenty of snacks and drinks (no alcoholic drinks), and there is a small selection of DVDs and board games available. A pizza dinner is included in the price for an overnight stay, and you can pay extra for a lobster dinner. It's a really cool experience to be watching TV and having a snack underwater while fish swim by your porthole window! The quarters are small but we didn't feel at all cramped.

You can do as many dives as you'd like from the lodge. This is a fairly murky lagoon however, so don't expect a thriving coral reef with a ton of different fish. Visibility is limited, and it's very easy to stir up the bottom. Still, there are quite a few things to see if you're patient. Plus you can get some great pictures of people through the portholes! There is also another habitat, MarineLab, nearby and there's a program that includes going in that habitat and seeing some of the actual research facilities. We didn't do that, though, we just swam over to it on one of our dives and looked in the window.

You get all the comforts of home, but obviously this is a place for adventure-seekers rather than luxury-seekers. Toilet paper has to go in a trash can rather than in the head, for example, and you won't find hair dryers or counter space for extensive toiletries. Bring the bare minimum with you, you don't need to dress to impress when you're down here! Also, access between the compartments is through round openings that can be somewhat challenging to climb into and out of - bear that in mind if you have any sort of mobility issues.

We found the staff to be extremely friendly and helpful. When we first arrived we got a tour of the topside facilities, including the "command center" - someone is on site the entire time that you're underwater, and there are various safety features, including a generator in case the power goes out. They told us to feel free to contact them if we needed anything, but otherwise they pretty much leave you to your own devices, so you can really have a great uninterrupted time.

There is wifi available, though we didn't try it out at all - we wanted to have a totally cut-off-from-everything experience, and posting updates to Facebook would have seriously detracted from that! Some people left notes in the guest book about talking to their family via Skype, though, which would be pretty cool. There's also a phone that you can use to make local calls, or credit card/calling card calls if you need long distance.

Overall, I really can't say enough about this place - our son was beside himself at the thought that he was living underwater!! I thought it was well worth the cost ($350 per person for 3-4 people for the overnight as of May 2014; different packages are available as well). Don't miss it if you're looking for a unique adventure!

Wow, steer clear of the dragon lady! She clearly leads a miserable life and doenst hesitate to spew her hatred of a pulse on her customers. While filling out the liability forms(which she repeatedly got mixed up between the 2 classes), my son saw a tv behind the counter with a neat scene of what I'm assuming is one of the underwater hotel rooms. My son asked her, with the wonder of a child enjoying the keys for the first time, "wow, what's that on the tv?".

"Something YOU won't be seeing", came the reply, with a snarl.

Being ex-military that takes no crap off anyone, especially when it's unwarranted and toward my son, I was about to reply, "the NICE way to say that is that that's one of our underwater hotel rooms. Theyre cleaning it now, so you unfortunately won't be able to see it today, but maybe you guys can come stay there one day". However, I bit my tongue, as I just wanted this woman out of our life asap, and we needed this place for my son's checkout dives due to bad weather, otherwise we would have never made it past the front desk. She also told me twice that I had to fill out the top of my liability form - as I'm busy filling out my son's. Tired of the holier than thou attitude, I replied, "I realize that, I can only do one thing at a time", with a smile.

On to the viz. The algae covering the bottom of the lagoon is as green and dark as the front desk lady's heart. Even in about 17 fsw, you can't see the bottom until you get a good ways down. I'd say it was about 10 feet of viz... but with the dark bottom, it seems much worse. My son, excited to get certified, called the dive - it was a bit scary even for me, an AOW diver with 100 dives and several night dives under my belt.

The whole reason I brought my son to Key Largo to get certified was because of the great viz and easy diving I've experienced over years of coming here. He will not have his first "ocean" experience ruined by bad viz and worse attitudes. If I wanted that, I could have taken him to Panama City for a lot less traveling than we did to get here(but at least the staff are friendly there). I'd rather he just finish his pool dives and finish his checkouts in the real ocean next year(it's been raining mercilessly our entire trip), where they should be done. No kid/new diver should be subject to having to "enjoy" their first "real" dives at this place.

We had never been diving before so we did the discover dive which taught you the basics of scuba diving. The instructor was very patient and had a great sense of humor, too. After we got down to the hotel we took a hot shower(the water pressure 30 ft down is amazing). Then they delivered our dinner & clean clothes. We watched Blue Lagoon while we ate. Of course, we looked out the port holes the entire time, too. The water is a little murky, but not too bad. We saw lots of angel fish and several other fish during our stay. Nobody stays down there with you, so you have complete privacy and freedom to go from room to room looking around. I highly recommend watching the History of Jules video while your down there. It's very interesting to learn about where you're staying. I would love to go again someday!

Thought I would stop by and find out more about this this place. The Lady at the gift shop was very unfriendly to my kids and other visitors. We had no food nor drinks and my kids were well behaved, just curious to look around their gift shop. Every visitor was greeted with you can't do this, don't do that. Not very friendly at all. We felt like we were a bother rather than a customer. Looked interesting but with that attitude not interested in going back.

We were looking for a hotel to stay during our visit to Key Largo and we figured we would check this out before we booked anywhere because it looked really cool! We stopped by the hotel and weren't exactly sure where to go and we ended up at the gift shop. We had never been to Key Largo and we decided to ask the worker in the gift shop some questions about the area. She was very rude to us and acted like we were idiots for some of the questions we asked. We just asked if there were any beaches/wildlife parks. We decided from this encounter that we would find somewhere else to stay, but I was disappointed because this place looked really neat. I didn't want to give them a bad review just by the gift shop worker, but just so they know they lost a customer because they weren't friendly. So, if you have the chance I would check this place out... but maybe steer clear of the gift shop.

I first heard of the lodge 5-6 years ago and when the opportunity came to visit it in Key Largo, we took it. I'm a fairly experienced diver but my two adult kids, who came with me, are qualified but inexperienced. There was no issues for any of us with the diving and there shouldn't be for novices (I'm a qualified instructor). In any event, the staff are professional and helpful.
The diving itself is easy and shallow, if unspectacular. The experience is the Lodge itself. We had a fantastic time and were very well fed. Despite that, we felt we had to order an underwater Pizza delivery, simply because we could! This is a unique experience, enhanced by the fact that the Lodge has an illustrious history, including a historic link-up with Skylab, when it was used for research.
In summary, highly recommended. To get the most out of a trip, try scuba beforehand and get a basic qualification, otherwise you will have to have some instruction on site.

We had the lodge to ourselves for about three hours when we signed up for the mini-adventure package. It set up back $150 apiece. We both are certified scuba divers, a prerequisite to visiting the lodge. We had our own snorkeling gear (mask, fins, and snorkel). The lodge operators provided, as part of the deal, the scuba gear. We received an orientation at 9 AM, the starting time of this package. By 9:30 we were suited up and fin-kicking our way, with our guide, down to the opening of the lodge, 21 feet below the surface. The water in this lagoon was somewhat murky, but we weren't diving on a coral reef in the open ocean.

We spent our allotted time down there peeking at the passing fish through a large circular window. Visibility was limited to maybe 10 feet. Still, we caught sight of angelfish, snapper, a juvenile barracuda, and a myriad of smaller fish. We dined on the pizza, brought down to us by our guide. There's a microwave in the lodge.

It was a most enjoyable interlude for the two of us. The reverie ended when our guide swam down and retrieved us around 12:30 PM. Dive over.

The lodge was originally an underwater research facility off Puerto Rico. For those wishing to visit the lodge who are not certified scuba divers, there is a type of certification offered here, for a fee, that will qualify a visitor to dive down and enter the lodge. Overnight packages are also available.

A unique experience, well worth the cost.
