Welcome to Tranquility Bay Beach House Resort, Marathon, Florida Keys

Halfway between Miami and Key West in the heart of the Florida Keys, Tranquility Bay is a 12-acre hideaway of palm-dotted white sand beaches overlooking the sparkling waters of the Gulf of Mexico. Opened in January, the resort features 87 charming two-story cottages on the ocean, surrounded by lush landscaping and towering coconut palms. The pristine sandy beach is one of the largest in the Keys, with endless watersports and activities (including Hobie Cats for rent), and the nearby Tilden's Scuba Center outfits divers keen to explore the sunken Thunderbolt wreck. Other fantastic Keys attractions are also nearby, including Bahia Honda state park, convenient shopping, great dining, and awesome sports fishing outlets. Pamper yourself at Island Spice Private Spa, or relax by the lagoon-style pool, tropical drink in hand. In addition to the luxurious accommodations, beach houses are also available for rental and ownership.
