On the airboat you would go through the River of Grass. This is a kind of shallow span of water that is wide and ranges from 6 inches to like 3 feet in depth. Moreover the waters are also home to different kinds of animal and plant species ranging from orchids to alligators. You would see a lot of varied wetland trees and plants coupled with bladderwort, water lilies and saw grass among others.
