Family Fun in the Summer Sun

Be prepared to make some serious decisions at Tranquility Bay. Each morning you’ll ask yourselves whether to start the day with poolside pampering or dive straight into an exciting range of onsite watersports. There are three swimming pools to dip in and out of, including an adults-only relaxation pool, while the kids will love making a splash in our lagoon-style tropical pool.

When it’s time to make some waves, our private beach is bursting with activities to help you explore the gleaming Gulf of Mexico, from kayaking and WaveRunner tours, to paddle boarding and diving. Back on land, there are volleyball nets to keep everyone on their toes while the waters gently lap against 2.5 acres of powder-soft white sand. Take a look at our new Resort Map to see how easy it is to navigate your way around our heavenly hideaway.

Meet the Locals

Nature-loving families will be in for a treat during a summer vacation in the Florida Keys. Aquatic birds, colorful fish, and resting iguanas are just some of the locals waiting to greet you in our ‘peace’ of paradise. Our resident resort cats can also be spotted basking in the sunshine and will become loved by the little ones.

Beyond the resort are many places to get a close-up look at the wonders of wildlife. One of the many reasons why families love Tranquility Bay Resort is its nearest neighbor, the Turtle Hospital. You will be amazed at the work carried out behind the scenes at the world’s only licensed veterinary hospital specializing in sea turtles. You may even experience nature at its best with the release of a turtle that has been returned to good health.

The Dolphin Research Center is another favorite among families, with opportunities to swim with these lovable marine creatures while learning about their behavior and characteristics.

Children’s favorites can be found on our special Little Caterpillars Menu, or the whole family can feast on the finest seafood fresh off the boat, served with a side of salty air and balmy breeze!

Thirsty for a Key Lime Colada? Meet our team of creative cocktail makers at TJ’s Tiki Bar and they’ll prepare to perfection your favorite thirst-quencher to toast your vacation in style.

Peace, Perfect Peace

As one of the best family resorts in the Florida Keys, Tranquility Bay is home to spacious two-level beach houses with a choice of two or three bedrooms and complete with a fully equipped gourmet kitchen, a separate dining area, laundry facilities and a living room with 42-inch wall mounted plasma TV. Open the French doors, unwind together on the porch and breathe in stunning views of the water.

Traveling on a budget this summer? Families can relax in our double queen guestrooms. More intimate than our larger beach houses, these super comfortable options still offer much more space than a standard hotel room.
