Tranquility Bay Beach House Resort

Tranquility Bay Beach House Resort in Marathon gives you access to a private 2.5-acre white-sand beach that you won't find at most Florida Keys properties, plus three pools and on-site water sports all in one spot. It's the kind of place where you actually unpack and settle in, with fully equipped kitchens, linens, and laundry in the units, plus spa services like aromatherapy and sports massage when you need to wind down.
