The park -- at the swamp's northern perimeter, on Cowhouse Island -- can occupy a day of your time. It offers boat tours (included with admission), canoe rentals, interpretive programs, an outdoor museum, marked trails, and even a serpentarium with reptile shows. Take a cypress boardwalk into the swamp to a 90-foot-high observation tower. You'll see lots of the swamp's most famous residents, a collection of cruising Georgia alligators. There are no overnight facilities, but food and beverages are sold.
