Treasure Harbor Resort is hidden gem, a treasure. We are an Old Keys Style Resort & Marina located within a private residential and protected harbor. Our laid-back Resort has an unique and fascinating history.

The harbor is 16-17 ft. deep as a result of dredging for construction of Henry Flagler's  Florida East Coast Railway, but the entrance, occasionally as low as 3 ft., is tide-restricted. Subsequent to Flagler's adventure, the canal was dynamited by Florida Keys "grandfather" of treasure salvage, Art McKee. The History of Diving Museum is right around the corner and has an exhibit dedicated to McKee.

The nearby Founders Park, provides swimming pool, beach, fitness path, ball fields, tennis & picnic areas to enjoy your fresh catch and relax for the sunset.

Treasure Harbor is also only minutes away by boat from “Hens and Chickens Reef” one of the best diving

And snorkeling reefs located in the upper keys.
