Located in the heart of the Florida Keys, Marathon is one of the Keys’ most treasured destinations, and Tranquility Bay is its newest resort. In fact, it is the only Florida Keys resort to offer property-wide high-speed (WI-FI) Internet access. Our 12-acre private enclave features original artwork and sculpture throughout the resort and is located directly on the Gulf of Mexico.

Stay in one of our beautifully appointed two and three bedroom beach homes, all with fabulous waterfront views, and enjoy one of the Keys’ largest private beaches, our stocked fishing cove, luxurious resort amenities and fine dining restaurant. With beautiful weather year round, Tranquility Bay is ideal for Florida Keys family vacations, romantic getaways, weddings, corporate retreats, special events and more.

During your stay take advantage of fun-filled children’s programs, in-room spa services and our Adventure Concierge to arrange fishing, snorkeling, diving, water sports and eco-tours. Sky diving, parasailing, helicopter tours and fighter jet rides also may be arranged. Our luxury Florida Keys resort is next door to the popular Turtle Hospital and minutes from Marathon’s Dolphin Research Center, where in-water dolphin encounters await. Sombrerro Beach, Bahia Honda State Park, and the museums and nature tails at Crane Point are among the many attractions nearby.

And, of course, no trip to the Keys would be complete without a visit to historic Key West, just 45 minutes away. Here’s a quick guide to Florida Keys attractions and Key West.
