Welcome to Tranquility Bay Beach House Resort

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. Wake up to the glistening waters of the Gulf of Mexico. Stay in a beach house or surround yourself in the tropics in a garden guest room. And let the powder-soft sand sift through your sun-kissed toes as you relax on the 2.5-acre private beach. Relax, *sigh*... you've arrived.
