Let's be real for a second: Turtles are awesome. And sea turtles are the coolest turtles of all. Not only do they live inside gorgeous shells and can grow to a massive nine feet and 1,500 pounds, but also they're known to migrate tens of thousands of miles to lay their eggs on exactly the right beaches. Just a two-hour scenic drive from Miami through the Florida Keys is a place where you can learn about these majestic creatures and even help ensure they'll continue returning to Florida shores for decades to come. The Turtle Hospital in Marathon is a nonprofit organization dedicated to rescuing and rehabilitating sick and injured sea turtles and releasing them back into the wild. Visitors can take a 90-minute guided tour that includes a presentation about sea turtles and a behind-the-scenes look at the hospital. At the end of the tour, you can even feed a few recuperating sea turtles. Admission costs $22 for adults and $11 for children aged 4 to 12.
