Tranquility Bay in Florida Keys

Discover a place like no other.

Nestled in the heart of the Florida Keys’ palm-lined paradise, in warm and welcoming Marathon, Tranquility Bay is a tropical oasis that’s easy to get to, but hard to leave. Because here you’ll make the memories that matter. Our private, standalone beach houses have private entrances with no hallways or elevators—completely apart from the crowd. With three pools, on-site watersports, and a private beach, you can do everything or nothing at all while keeping your distance in this relaxing, tropical oasis. Wake up to the glistening waters of the Gulf of Mexico in a beach house or surround yourself in the tropics with a garden guest room. Relax, *sigh*… you’ve arrived.
