Nesting Sea Turtles

The main turtle nesting months run from May through October, though it’s not unusual for leatherbacks to start earlier in the year. If you are lucky enough to spot a nesting sea turtle in the sand, remember to allow her plenty of space and avoid shining a light or using flash photography. The health of sea turtles is taken seriously in the Florida Keys. For a behind-the-scenes look at the rehabilitation of sick and injured turtles you can visit the Turtle Hospital which is located right next door to Tranquility Bay and offers guided, educational tours.

Dolphin Encounters

Have you ever wanted to get waist-deep in the water with one of the world’s most loved marine mammals? Take time out in Marathon to learn more about dolphins at the Dolphin Research Center on Grassy Key, where a series of saltwater lagoons are carved out of the shoreline to provide a sanctuary to a family of dolphins and California sea lions. You’ll pick up fascinating facts about the behavior of these sea creatures before delving into the water for an unforgettable encounter with dolphins.

Diving guides from Turtle Island Watersports will open your eyes to some of the most incredible dive sites nearby, including mysterious shipwrecks and the only living coral reef in North America.
