Emeralda Marsh Trail is a smooth, wide dirt path shared by hikers and bikers. This area was designated a National Natural Landmark in 1974, and the district began restoring it in 1991. Restoration gave former farms flood control and managed water levels to encourage wetland development. The marsh is actively managed and improves the water of Lake Griffin and the Ocklawaha River. The area is home to diverse wildlife, including sandhill cranes, various duck species, bald eagles, white pelicans, and a good amount of alligators.
