For primitive overnights, you can camp free of charge on Elliott Key, which is part of Biscayne National Park and is accessible only by boat. Facilities include showers, rest rooms and drinking water. You must haul your own trash off the island. If you spend time in the Everglades, you'll have no problem spotting alligators. Here, you can see how they are farmed and handled.
Snakes add to the creepy crawliness of the place.
A 30-minute airboat ride provides opportunity to observe hawks, ospreys, roseate spoonbills, and, of course, alligators in their natural habitat. The farm also introduces you to caged bobcats, cougars and an American black bear and presents alligator and wildlife shows. One exhibit that kids like identifies the calls of cricket frogs, limpkins and other noisy park residents. A map directs visitors to trails and other facilities along the 40-mile road on the park's east access. Others penetrate slash pine, hammock mahogany, saw-grass prairie and cypress environment.
