I’on Swamp

In particular, because the most elusive bird in America, Bachman’s warbler, has been spotted here.

The area provides wide range of wildlife viewing, especially the numerous large alligators that come into view where the trail crosses one particular pond. The trail’s backstretch pushes into gorgeous wetlands dotted with bald cypress trees and murky swampland.
