Cruises to Key West are packed with coastal-town energy and layers of American history just waiting to be discovered. Enjoy a laidback Caribbean vibe with a dash of the high life on Carnival cruises to Key West. The southernmost island of the Florida Keys, Key West is a sunny, fun-loving place with plenty of charm, and more than a little touristy goofiness. (But that’s optional.) Key West cruises deliver you to palm-shaded streets lined with gaily-painted bungalows, vintage saloons and blooming tropical flowers. Whether life’s a beach or you’re life of the party, cruises to Key West definitely over-deliver.
