Tranquility Bay Beachfront Resort
Welcome to the Lighter Side of Paradise

Tranquility Bay is a beachfront haven where you can do it all — or nothing at all. At our Florida Keys hotel and resort, we provide a serene escape from the go-go-go of daily life. Here you’ll find both an unforgettable beach vacation and a restorative experience among the swaying palms and gentle waves of the Gulf of Mexico.

Grab a kayak or nap, read a book or a menu, work on your tan or your second piña colada — this is one vacation you won’t need to recover from.
