I had a great experience here with Sea Dwellers Dive Center of Key Largo. My mom mostly speaks Spanish and we had an amazing instructor called Sebastian who spoke Spanish. He answered all of our questions and reassured us that everything would go smoothly. We went for snorkeling but will definitely return for the diving since it looks like so much fun. I heard from other people on the dive that this company was actually better in comparison to the other companies due to the personal one on one experience. Also if you get sea sick do your research. My mom got really sea sick and had to stop snorkeling. But overall the staff were friendly and safety-conscious.

My wife Amy and I spent three incredible days diving with Sea Dwellers in Key Largo, and they absolutely set the standard for what a charter should be. Captain Kate is phenomenal — she made sure every dive site we needed was available, and it was the little things she did that made us feel genuinely taken care of. The onboard instructors — Emily, Sebastian, Jasmine, and Merlin — brought the perfect mix of professionalism, fun, and positive energy to every trip. Whether you’re an instructor, a certified diver, or a brand‑new beginner, this team knows how to create a safe, enjoyable, and memorable experience. Sea Dwellers earns my highest recommendation. If you’re diving in Key Largo, this is the crew you want to be with. Jason Miller, PADI IDCS-557649
