Family favorites

Get up close to nature

A family vacation in Florida isn’t complete without meeting the local wildlife. From the sick and injured sea turtles being rehabilitated at Marathon’s Turtle Hospital to the endangered Key deer roaming Big Pine Key, there’s an abundance of nature to discover here. Swim with dolphins at the Dolphin Research Center, and meet the herons, owls, pelicans and egrets at the Florida Keys Wild Bird Center in Tavernier.


Embrace your inner pirate

Visit Crane Point Hammock in Marathon and explore its 63-acre environmental and archaeological preserve. Discover the history of the Keys, including the pioneers, pirates and explorers, and greet the native marine life at the museum’s touch tanks, which features sea urchins and starfish.


Make a splash with water sports

The best way to enjoy our island paradise is on the water. From kayaking and snorkeling to fishing charters and leisurely cruises, our Adventure Concierge can help you coordinate activities during your stay. Ready to dive into adventure?


Unwind with a beach day

As well as the serene swimming beach right here at Tranquility Bay, you’ll be spoilt for choice with the stunning sandy beaches in the Florida Keys. Our top picks? Sombrero Beach at Mile Marker 50 is one of Marathon’s most popular spots, with walkways, picnic areas and a roped-off swimming area, while the peaceful Coco Plum Beach at Mile Marker 54.5 offers a quiet escape.


Count bridges along the Overseas Highway

One of America’s most scenic drives, the Florida Keys Overseas Highway stretches from north of Key Largo to Key West, with 42 iconic bridges connecting the islands. Challenge your family to see who can be first to count them all – that is if you don’t get distracted by the glimmering waters of the Atlantic Ocean, Florida Bay and the Gulf of Mexico!
