Sabine National Forest in East Texas near Louisiana spans 160,873 acres across several counties and emerged largely through Civilian Conservation Corps work in the 1930s, when CCC companies planted pines and built roads, lookout towers, recreation areas, and campground facilities. Known for extensive American beech, hardwoods, and mixed pine forests, it includes the 28-mile Trail Between the Lakes for hiking and primitive camping. Its Indian Mounds Wilderness, added in 1984, protects botanically important ridges and slopes containing rare mature black hickory stands and the largest known old-growth American beech and southern magnolia forest in any U.S. national forest, alongside diverse Piney Woods wildlife.
