Locations are finalized the day of trip based on conditions. This combination dive & snorkel trip will be approx. 25 feet deep from the surface to sand. The coral formations are very dynamic & come off the bottom 8 - 15 feet so you're still up close, see more critters like sharks, turtles, rays, eels & TONS of reef fish than 'snorkel only' spots with nothing but tiny reef fish & you can be vertical in the water without damaging the reefs like in the extremely shallow 'snorkel only' locations. Please arrive ON TIME... We can't hold the boat for late check in. Snorkelers MUST know how to swim & be comfortable in water where you can't stand.

Our trip to the reef was excellent! My husband and I were celebrating our anniversary and birthdays and the staff made it a memorable day! Captain Dave, Jasmine, and Tony were very accommodating and they went above and beyond to make it extra special! Erica in the office was kind and so welcoming! You all made this a trip we will remember forever! Thanks for everything! We will come back next time we’re in the Keys!

Very proud to be a part of a diving center that goes above and beyond to rebook, coordinate and make things right no matter what. They are honest, transparent and let you know when conditions aren't the best to ensure that the experience meets expectations. The pricing is comparable and over a week long trip the crew never bends to be the best in the industry. Happy, encouraging and safe are all words I would associate with the Sea Dwellers Crew. The boat was full but with the bow space there was plenty of room to move around, store gear and the snacks were awesome! If you are looking for a great time out on the ocean with professionals that make you smile this is the outfitter you want!

I almost never leave reviews, especially not ones bashing something this hard, but our “guided snorkel tour” experience was so bad that i feel i have to. When we arrived at Sea dwellers dive center, that we booked through, they told us their boat was under maintenance and that we were meeting at a different location. okay that’s fine. after lots of not being able to find where we’re supposed to be, we see people gathering and it turns out they’re waiting for the same tour. after another 45 minutes, we finally push off 30 minutes after the scheduled time. the only redeeming quality about this trip was that the molasses reef was beautiful. the “tour guides” who did no guiding or touring at all, were completely focused on the scuba divers. i understand that scuba diving can be dangerous and that it’s important to be more vigilant with those diving, i really do. but if you’re a snorkler, DO NOT book with this company. you will be virtually ignored and there’s no guiding going on. there was no communication about anything that was happening, we saw multiple people throwing up and they were ignored just like us. you would be better off booking with quite literally anyone else. we’ve done around 10 off shore tours now, and this one is the worst one by a mile. i hate to leave a review this abysmal but i feel very strongly about how awful our experience was.

Emily and Captain David were well trained in their art and made sure everyone was safe while ensuring we all had a great time! The locations were like no other, and my friend and I had an awesome experience out with these two!

My Husband and I had such a wonderful time! We left the dock at 1pm and returned at 4pm. The price we paid ($140 for two people) was reasonable for a three hour tour! (Snorkel) Krissy, Erica and Merlin(aka, Jacob) were excellent hosts! We never felt rushed and they gave fantastic instructions on everything.

Had a great time and saw a bunch of fish! The first stop had a lot more to see than the second, but on the way to the second location we saw some dolphins! Erika was amazing with my older teen who was struggling with snorkeling and the whole crew worked to make it a good experience for her. She was smiling by the end!

Sea Dwellers was an awesome outfit!! Super nice people, very safety conscious, and helpful. Tony and Erica were especially great! The snorkeling was first class. We went 2 spots- a shipwreck and a lovely reef. There were both divers and snorkelers on the boat. I was concerned that the sites would too deep for great snorkeling but I was happy to be wrong! The visibility was so great it was easy to see everything. My husband and I really enjoyed it and thought it was one of our top snorkeling adventures- and we've done a lot! If you're considering doing this- do it!! Well worth it.

Awesome staff and Captain Dave was a very safe and competent (and funny) driver. We stopped at two deep snorkel spots but saw plenty of fish and even saw an eagle ray swim on by. Definitely a great company to trust for a fun snorkel trip!
