The Ozark-St. Francis National Forest is a United States National Forest that is located in the state of Arkansas. It is composed of two separate forests, Ozark National Forest and St. Francis National Forest, each with their own biological, topographical, and geological differences. Together, the two forests are home to 23 developed campgrounds, and include nine swimming areas, 395 miles (636 km) of hiking trails, and 370 miles (600 km) of streams for fishing. The majority of the trails in what are now the Ozark National Forest and St. Francis National Forest were constructed under the Works Progress Administration and Civilian Conservation Corps.
The Forest contains 11,000 acres (45 km2) of old-growth forests.12 The old-growth forests typically occur in the southern portion of the Forest on ridges and steep south-facing slopes and are dominated by Shortleaf Pine and various oaks, including Post Oak, Blackjack Oak, Eastern Black Oak, White Oak, and Northern Red Oak.3 The Forest is also home to six different endangered species.
Several National Scenic Byways cross the Ozark-St. Francis National Forest, including the Scenic 7 Byway which runs from Missouri to Louisiana, 60 miles (100 km) of which are within the Ozark National Forest. Scenic 7 Byway offers the greatest variety of Ozark topography and scenic vistas. The Ozark Highlands Byway provides access to the Mulberry River, Big Piney Creek, and Buffalo National River for fisherman and canoeists. The Mount Magazine Byway offers scenic overlooks of the Arkansas River Valley, and the Sylamore Scenic Byway offers a scenic drive to the Blanchard Springs Caverns. Forest headquarters are located in Russellville, Arkansas.
