This city in Florida is home to a major thoroughbred breeding center. There are only about three other such facilities in the world. As such, Ocala offers plenty of horseback riding opportunities. After you ride like the wind on land, you may want to take it easy and gently sail on glass-bottomed boats at Silver Springs State Park. For a little bit of history, you can head over to Historic Downtown Square where you'll see buildings dating back from the time Ocala became the first town in Marion County during the 1800s.
