Discover Marine Life Up Close

One of the most meaningful things to do in Marathon is visiting The Turtle Hospital, a working rehabilitation facility dedicated to rescuing and treating injured sea turtles.

Florida Keys Aquarium Encounters
For hands-on marine experiences, Florida Keys Aquarium Encounters is absolutely one of the best things to do in Marathon Florida with the whole family.
