Rainy days can still be good days on the water.

First off, Ivy and Capt. Rick were amazing! I was a little worried because we woke up to storms, and the most recent review had shown murky water (Not something the crew can control). Very happy we decided to give it a try.
Our snorkel site was called White Rock reef and the reef was alive and colorful. Healthy soft corals, sea fans, and a large variety of fish.
When you first get off the boat, the water is murkier and deeper. A short swim over the reef had water that was more clear.
Wish we had another day here to go out with them again.

Don’t waste your money booking this trip!
karenlN4806BS, October 2026
Worst tour I’ve ever been on. Don’t waste your money!
We spent barely an hour in the water and saw nothing but sand and water. Honestly, we could have had the same experience swimming at the beach for free.
The captain rushed through the instructions like he was reciting a script. He wasn’t friendly or engaging and showed no interest in making sure we had a good experience. It felt like he was just trying to get the job done. Everyone seemed disappointed, and he couldn’t have cared less.
When we returned, the office was already closed, so there was no one available to speak with about our concerns. The whole experience left us feeling like they cared more about taking our money than delivering a worthwhile tour.
I would absolutely not recommend this trip to anyone.

Awesome experience. Awesome crew.

From the shop to the ship, the employees are great. Excellent captain and guide on ship. Helped make the experience very smooth and stress free. I've never really went snorkeling except messing around in the pool or sumthin so i admit, i was a little nervous but they put you at ease on the ride out. The experience is incredible. The things you see there are so beautiful and it's amazing to see nature in action while they behave as if you're not even there. We had maybe 15-20 other people on the boat with us, but that did not effect our experience at all. I could have stayed in all day but for most people, including my wife, the 1h+ in the water was perfect. For how cheap it is, you can't beat it. Next time that I'm in the keys i would love to see the Christ of the deep with them!
Side note: you have to purchase your own snorkel at the shop($15). Not a big deal but figured i would put that in jic. I know how some people are.
