Ben Lilly Conservation Area is a 247-acre protected tract in Morehouse Parish, Louisiana, north of Bastrop. Beside Chemin-A-Haut State Park and largely encircled by Bayou Bartholomew, it is named for big-game hunter Ben Lilly, who guided Theodore Roosevelt on a 1907 bear hunt in the Tensas River swamp. The Louisiana Department of Wildlife and Fisheries acquired the property in 2013. It is reached through the state park from U.S. 425, and boat access is also possible, with a boat ramp planned.
