Airboat alligator safari at Gator Park, Everglades

A flat-bottomed boat with a large fan at the stern skims across the sawgrass and shallow water of the Everglades. When the engine drops, the guide slows, and alligators sunning at the water's edge come into clear view. The flat, wide, humid landscape shows its real scale once the boat stops.

The engine is very loud, so think about ear protection. Bring sunscreen, a hat and a strap for your sunglasses, since small items can fly off in the wind. A cover keeps your phone safe from spray.
