Sea Dweller Snorkeling & Scuba Dive Trips in Key Largo

Enjoy a relaxing 3.5-hour tour on our custom 50 Foot Dive and Snorkel Vessel, The Sea Dweller III.  As the ONLY Marine Management boat in the Florida Keys, The Sea Dweller III has plenty of room to move around compared to the standard Newton or 6-passenger dive boats you find elsewhere.  All our boats are Coast Guard-inspected vessels, ensuring that we have the most up-to-date safety features and training for your family.  Enjoy complimentary drinks and snacks, while you are able to sit back and relax the way diving and snorkeling is meant to be.

Our standard trips include 2 Locations, and we will have time to snorkel for over an hour at each location.

Enjoy 2 locations on our shallow reefs of the Upper Keys National Sanctuary. As a protected reserve on the largest reef structure in North America, Molasses Reef delivers the finest diving and snorkeling in the Keys!
