Marathon Key

If you’re an animal lover with a penchant for turtles, then this should be your first port of call when cruising the keys. The Turtle Hospital here has been open since 1986 and has cared for more than 1,500 loggerhead turtles. It’s possible to take a guided tour of the hospital to see how they rescue, rehabilitate and release sea turtles of all ages. Just know, it’s quite an emotional experience.
