The Florida Keys is home to one of the most diverse and unique ecosystems in the world. In this video, local wildlife biologist Christina Wilson takes you on a tour of its iconic sites both underwater and on land. Below its aquamarine waters, this extensive island chain preserves the only living coral barrier reef in the continental U.S., which sustains diverse marine wildlife that you can see up close while scuba diving in Key Largo. Plus, you can even spot sea turtles, dolphins, and giant stingrays from the historic Old Seven Mile Bridge and indigenous Key Deer at the National Key Deer Refuge. There’s no shortage of things to do in the Florida Keys, especially when it comes to unbelievable views, gorgeous waters, and unique wildlife.
