Relax at Our Florida Keys Resort

Tranquility Bay Resort, amenities, & dining outlets are all open

At Tranquility Bay, peace and serenity is assured. We take inspiration from our neighbors in the Caribbean, with an abundance of tropical palm trees lining our turquoise waters, creating a paradise that’s worlds away from your everyday life.

Our private 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.

So sit back, relax, perhaps enjoy a cocktail, and make memories that will last a lifetime.
