John Pennekamp Coral Reef State Park

The park's underwater claim to fame is a stretch of living coral reef you can snorkel, dive, or view from a glass-bottom boat without getting wet. Campgrounds at John Pennekamp come with full hookups and grill setups, and the primitive group sites suit the kind of people who still know ghost stories. Mangrove paddle trails and reef dives fill the daylight hours, and boaters can moor overnight and wake up on the water, about an hour from Miami.
