Having a very diverse geographical and plant environment, Caldwell Parish is home to the nearly one-thousand acre Copenhagen Hills Preserve, located southeast of Copenhagen. Run by the Nature Conservancy, it attracts botanical and archeological enthusiasts from a wide area. The University of Louisiana at Monroe owns an eighty-acre outdoor classroom, the Dr. Charles Allen Nature Preserve, located near Hough Bend, that is used primarily for tree identification. The U.S. Army Corps of Engineers owns an outdoor preserve located on Lock and Dam Road. Together with its rivers, lakes and bayous, and the 51,000-acre Boeuf Wildlife Management Area, Caldwell is a huge attraction for hunters and anglers.
