1.25 mi or 2 mile boardwalk tour through cypress swamp. We took over 3 hours to do the 2 miles. Lots to see, no hurrying necessary. Have the kids use restrooms (located just before you get on the boardwalk) before you start out, as no facilities once you leave the parking lot. You can still hear some traffic noise, but it's still a peaceful walk. Saw alligators (big and small), numerous turtles, lots of birds, sleeping cottonmouth, squirrels. Possibilities of seeing otters, but we weren't that lucky.
