Tranquility Bay Beachfront

A Sheltered Keys Lagoon

The camera looks out over the private beachfront of Tranquility Bay Resort, where a curving lagoon of shallow, glassy water is protected from the open ocean. The tranquil bay is emblematic of the Florida Keys, a chain of coral islands strung across the warm waters between the Atlantic and the Gulf of Mexico.

Palms, Sand and Loungers

Rows of tall coconut palms rise from the soft white sand, casting long shadows across the beach. Clusters of lounge chairs and umbrellas face the water, capturing the relaxed, resort atmosphere that draws visitors to Marathon.

Marathon in the Middle Keys

Marathon sits at the heart of the Middle Keys, roughly halfway along the Overseas Highway between Key Largo and Key West. It is a hub for fishing, diving and boating, and its warm, shallow flats make it one of the most inviting coastlines in Monroe County.
