Daily Reef Adventures for Florida Keys Diving

The Only Living Coral Reef in North America

Colorful tropical fish, beautiful corals, moray eels and more are waiting to be discovered beneath the Keys' pristine waters in a Florida Keys diving adventure. Come with the Turtle Island Adventure crew to explore the only living coral reef in North America, aboard one of their fully equipped vessels for a Florida Keys scuba diving experience you won’t soon forget. The "Turtle," a 34-foot Crusader, a six-passenger vessel. The "Sea Diver" a 30-foot, twenty-two-passenger vessel or the forty-nine passenger, 45 foot Corinthian Catamaran "Island Time."

The reef is located just 3-4 miles offshore and is only a short 30-minute boat ride from the docks. Families with both divers and snorkelers can go together on the same boat for their ideal Marathon diving excursion. The majority of our beautiful reef line is only 30 feet or less, but there are special spots for a wide variety of dives.

Here are some of Turtle Island Adventures outstanding Marathon scuba diving and snorkeling adventure locations and their depths.
