My fiancé and I booked online with Lost Reef Adventures for our first ocean dives. We were…read morecertified back in October in a fresh water quarry. The day we went, the waves were pretty choppy. I got in the water and panicked. Kelly, our guide, expertly made sure I got back to the boat. Spencer, our dive master, helped me up and reassured me the whole time. I got to spend the next couple hours hanging out with Spencer and robin (the captain), which honestly, was a great time. What I loved is how committed they were to safety, and also making me feel valid in my decision to abort the dives. My partner successfully completed two dives and had a fantastic experience with Kelly guiding him. If/when we're back in key west again for diving, we will definitely book with Lost Reef again!!

Lost Reef Adventures...the worst dive shop that I have encountered in 30 years of scuba diving…read more The negatives: The owner, Nick, was extremely unfriendly to the point of being hostile. He had a serious attitude problem and had no idea what the concept of "customer service" meant. He just stares at you, waiting for you to say something...it's really creepy. After telling us to show up at 7:00 for the morning dives, no one from the shop bothered to show up until 7:45. The crew was only okay. The dive master acted like this was an annoyance to be taking us out on a dive...like he just wanted to get this over and done with. He just swam around for 45 minutes until it was time to re-board. The boat pilot told us, "We're not leaving the dock until you get your gear ready." There was one guy (with a mullet and ear rings) that was pretty cool and very helpful. The equipment was fair, but had some issues. The first tank that I hooked up to only had 1200 psi, turns out that 1/4 of the tanks onboard had previously been used and not removed or refilled. The fact that they all had the rubber covers on the valve (indicating a fresh tank) made it very confusing as to which tank to use. My dive buddy's regulator was inoperable. The dives were fair at best. I guess Key West really isn't that great for sea life when compared to the USVI or Belize, buy the dive master didn't even bother to point out sea life. EVERY dive I've been on in 30 years had a dive master that took pride in his/her job and did their best to point out - things to see - during the dive. I told the travel office on the base at Sigsbee not to recommend them. There are vastly superior shops like Southpoint Divers and Captain's Corner that will give you a much more pleasant experience. I dove with Southpoint on all of my subsequent dives in Key West. The positives: The boat was great - lotsa space for everyone, safety equipment was plentiful, and the safety briefing was well done. As I mentioned before, one of the crew (lives in Roatan, Honduras and was visiting his daughter) was very helpful but unfortunately, he was the exception. The BCDs, masks, and fins were fine. There's not really anything else positive that came out of my experiences. Do yourself a favor and use one of the other dive shops in Key West.

My 16yo son, Jake, & I participated in the beginner scuba course on Wednesday, June 3, 2026, & what…read morean incredible experience it was! We came in with absolutely zero scuba diving experience, so we weren't quite sure what to expect. We met our instructor, Tommy, at the Hilton Hotel pool, where he walked us through the basics, including hand signals & important safety information. His teaching style was clear, patient, & reassuring, which helped ease my nerves right from the start. Once we got suited up and into the water, Tommy made sure we were completely comfortable with each step before moving forward. He also took extra time afterward to answer all of our questions, which we really appreciated. Later, we met at the dive shop at 12:30 PM, headed down to the dock, & joined our captain, Drew. From there, the adventure truly began. It's honestly hard to put into words just how amazing the entire experience was. Everything was perfect, and I wouldn't change a thing. During our first dive, I had some difficulty clearing my ears, but Tommy stayed right by my side the entire time. He patiently guided me up & down the rope, allowing me to adjust at my own pace until I was comfortable. At one point, I started to feel anxious, as he had taught us, I signaled it, with a bit of panic beginning to set in. Tommy immediately recognized it, calmly reassured me, & helped me regain my confidence. Thanks to his steady guidance, I was able to relax & truly enjoy the rest of the dive. We completed two separate reef dives (each with a tank), & the underwater world was breathtaking. We saw a sea turtle, a stingray, a goliath grouper, lobster, trumpet fish, lionfish, and thousands of other beautiful fish. Tommy did a fantastic job pointing out marine life we would have otherwise missed. Scuba diving is something I've always wanted to try, & thanks to the passion & enthusiasm of both Tommy and Drew, my son & I are now completely hooked. We've already signed up for the open water online course & are excited to continue toward our certification. If you have the opportunity to take this excursion, don't hesitate, it's an unforgettable adventure. Thank you, Tommy & Drew, for making this such a meaningful & inspiring experience for both of us. You've truly sparked something special! Chris & Jake Mueller Oglesby, Illinois

We felt totally at ease and had a lot of fun. Couldn't wait to get back out so we signed up for a night dive with Southpoint but visibility was too poor for the dive to go out so we rescheduled for the Vandenberg wreck. Honestly, if we hadn't gone out with Dean already we wouldn't have done a 100 foot wreck dive. So glad we did! Never felt unsafe - Southpoint's focus on safety and preparedness was obvious - and we had an experience we'll never forget. Such an iconic dive, not to be missed. Hoping to get back to Key West in the not too distant future and, if we do, we're definitely going diving again with Southpoint.

Woman-owned and in business for 40 years, the owner is a legendary woman diver on her own right, though Leslie will never tell you that herself. I earned my Divemaster certification with Captain's Corner in 2020 and regard their training as excellent, tailored, and safety oriented. I've dove with other Key West operators, but this is the one most focused on making your experience fun while maintaining high levels of professionalism, expertise, and safety awareness. Plus, I vouch for the quality of their equipment, which I've been renting for 5 years. The mouthpieces are always new, the BCDs well cared for. I personally see the diligence they take in cleaning and caring for their equipment. Not to mention, Key West has some incredible dive sites. On the reef with CC just two days ago, we saw reef sharks, porcupine fish, hogfish, tons of reef fish, and dolphin encounters on the way out and back in to the harbor!

The dive shop was organized and the process through the morning went smoothly. For a 9AM boat time, we got to the ship just before 8AM. The waiver process, just like the process to register for the dives, was smooth and well rehearsed. Gear issue and transportation to the boat were seamless. All the folks in the shop, on the boat, and diving with us were so friendly, informative, and personable, and most importantly made us feel safe! Disclaimer: I'm a super novice diver so my only goals were to be safe, see some fish, and reinforce the basics of scuba. All three of these goals were achieved with the help of Captain Hooks! Once on the boat, we got all gear issued and did two 45-min reef dives. Wildlife was great, gear was great, and so was our dive master! Truly exactly what I was looking for. I would gladly sign up for more dives with this team!
