More than just a passenger. You're our guest.

Marathon Mermaid and Morada Mermaid aren't part of a large corporate tour company. We're a locally owned and family-operated Florida Keys business built around our love of the ocean and the communities we call home.

What started with Marathon Mermaid and a dream of sharing our favorite waters with visitors has grown into a Mermaid family, with adventures now departing from both Marathon and Islamorada. But as we've grown, what matters most to us hasn't changed. We're still local. We're still family operated. And we're still incredibly grateful every time someone chooses to spend part of their Florida Keys vacation with us.

When you step aboard either Mermaid, you're more than just a passenger. You're our guest, and our goal is to give you the kind of day on the water that makes you understand why we love living here.

Come as our guest. Leave as part of the Mermaid family.

We were a group of 6 and all of us had a great time. The captains were so fun and knowledgeable. They made sure everyone was safe and knew what to do. They were so patient with the first time snorkelers. They provided soda, water and chips. I would absolutely recommend this adventure to my friends!
