The Atchafalaya National Wildlife Refuge, west of Baton Rouge, lies in the heart of North America's largest wetland. White-tailed deer, herons, river otters, and even alligators live among mighty cypress trees, flooded depressions, and quiet bayous, warming themselves on sunny banks or gliding silently through the water. Over 200 species of birds can be observed here. The natural dynamics of the water—flooding in spring, retreating in summer—make the area a biodiverse habitat and a popular destination for anglers, hunters, and nature observers. The best way to explore the nature reserve is on an airboat tour.
