More than half of the 180 miles from Johnson Bayou to Grand Chenier are perched above the area's brackish water—teeming with alligators—on levees and stilted bridges. Explore this “Louisiana Outback” trail and surrounding saltwater marsh acreage with Grosse Savanne Eco-Tours. Guided two-hour to full-day tours take you to remote watery corners where over 300 species of birds flourish; the area is also home to the largest American Alligator population in the U.S. Looking for a cheaper way to see the sights?
