Jean Lafitte National Historical Park and Preserve (Lacassine Unit) Adventures

The Lacassine Unit of Jean Lafitte National Historical Park and Preserve encompasses over 35,000 acres of coastal marshes located in Cameron Parish, Louisiana. This unit is characterized by its vast freshwater, brackish, and saltwater marshes, along with bayous and lagoons that form an important habitat for a diverse range of wildlife, including migratory birds, alligators, and numerous fish species. The area lies near Lacassine National Wildlife Refuge and is part of a larger network of protected wetlands critical for water filtration, flood mitigation, and storm protection. Established in 1994 as a unit of Jean Lafitte National Historical Park and Preserve, the Lacassine Unit preserves one of the largest remaining coastal marshes in Louisiana, an ecosystem threatened by erosion and human development. Recreational activities focus mainly on wildlife observation, birdwatching, and photography, especially during the migratory seasons when waterfowl are abundant. The unit also supports fishing and paddling in designated waterways, providing a quiet, natural experience away from urban centers. Unlike the park’s other units, there are no developed trails or campgrounds here, emphasizing conservation and low-impact visitation. Visitors are drawn to the natural serenity, abundant wildlife, and the opportunity to visit a relatively untouched coastal landscape that represents Louisiana's unique ecology. The protection of this unit helps maintain critical habitat for several endangered and threatened species and sustains important ecological functions that benefit the Gulf Coast region.
