Ozark National Forest

Ozark National Forest is the vast, wild backbone of northern and north-central Arkansas, covering more than 1.2 million acres of the rugged Boston Mountains — the highest and most rugged section of the Ozark Plateau — and rolling highlands stretching toward the Arkansas River Valley. It is a landscape of towering sandstone bluffs, deep hollows, clear Ozark streams, waterfalls, and some of the most remote and biodiverse forests in the central United States, protecting the headwaters of the Buffalo, Illinois, and Mulberry rivers.

Within its boundaries lie the majority of Arkansas’s congressionally designated wilderness areas, including the Upper Buffalo Wilderness (home to Hawksbill Crag), the Richland Creek Wilderness, the Leatherwood Wilderness, and others — preserving some of the wildest and least-disturbed land in the mid-South. Blanchard Springs Caverns, one of the finest show caves in the nation, lies within its boundaries, as do hundreds of miles of trails, rivers for floating, and overlooks across seemingly endless ridges. Rugged, remote, and rich in natural and recreational wealth, Ozark National Forest is a treasured natural anchor of the Arkansas Ozarks.

Ozark National Forest offers exceptional recreation across its vast, rugged terrain — hundreds of miles of hiking and backpacking trails through wilderness areas and over bluffs, canoeing and kayaking the wild Buffalo, Illinois, Mulberry, and other Ozark rivers, visiting the spectacular Blanchard Springs Caverns show cave, mountain biking, horseback riding, fishing for smallmouth bass and trout in cold Ozark streams, primitive and developed camping, and stargazing under dark skies in the remote hollows. The forest is also the gateway to Hawksbill Crag, the most photographed spot in Arkansas, set within the Upper Buffalo Wilderness.

Spring brings high water for Ozark river floating, wildflowers, and cascading waterfalls in the hollows, while fall is spectacular, with vivid color across the Boston Mountains ridges and ideal hiking weather — the premier season for the forest’s scenery. Summer offers swimming holes, river floats, and the cool shelter of the deep hollows, though it is warm and humid. Winter brings quiet trails, bare-ridge views, and solitude in the forest’s remote backcountry. Spring for rivers and falls, fall for color and hiking, and any season for Blanchard Springs Caverns (which maintains a constant cool temperature year-round) are the seasonal highlights.

Ozark National Forest was established in 1908 under President Theodore Roosevelt’s conservation program, protecting the rugged, commercially logged Boston Mountains and Arkansas Ozarks that had been heavily cut in the late 19th century. Over the following decades, reforestation and protection allowed the forest to recover its wild character, and Congress later designated multiple wilderness areas within its boundaries to preserve the most remote lands. The forest has long been central to Ozark hill culture, with its streams, timber, and wild lands woven into the heritage of the region’s communities.

The Boston Mountains, the highest and most rugged section of the Ozark Plateau, form the heart of Ozark National Forest. Here, ancient layers of limestone, sandstone, and shale — deposited in warm inland seas hundreds of millions of years ago and later uplifted and eroded — have been carved by streams into the deep hollows, spectacular bluffs, waterfalls, and caves that define the landscape. The soluble limestone creates karst features including Blanchard Springs Caverns. The resistant sandstone caps the high ridges and towers as the dramatic bluffs along the wild rivers. The forest’s complex geology underpins its remarkable scenery and biodiversity.

Ozark National Forest supports a rich and recovering wildlife community, including black bear (populations have rebounded strongly), white-tailed deer, wild turkey, bobcat, river otter, and the reintroduced elk herd that roams the Boxley Valley near the forest’s northern edge. The cold, clear Ozark streams support smallmouth bass, Ozark hellgrammites, and rare native mussels. The forest’s caves shelter significant bat populations, and its skies and forests harbor diverse woodland birds and raptors. The wilderness areas and remote hollows provide refuge for wide-ranging species, making the forest one of the most wildlife-rich landscapes in the mid-South.

Ozark National Forest protects a vast and biodiverse Ozark ecosystem, where the rugged Boston Mountains, the wild rivers, the limestone caves, the bluffs, and the recovering forests support exceptional plant and animal diversity. The forest harbors rare endemic species adapted to the Ozark Plateau, including cave-adapted invertebrates, cold-stream fish, and specialized bluff-face plants. Its designated wilderness areas protect some of the least-disturbed forest in the mid-South. The clear Ozark streams are among the highest-quality cold-water systems in the region. Protecting water quality, the caves, the wilderness areas, and the forest’s biodiversity sustains this irreplaceable ecological resource.

Ozark National Forest is deeply woven into the cultural fabric of the Arkansas Ozarks, where generations of hill families have hunted, fished, floated rivers, and lived close to the rugged land the forest protects. Its wild rivers, the landmark Blanchard Springs Caverns, the iconic Hawksbill Crag, and the remote wilderness areas have become beloved symbols of Ozark identity and natural heritage. The forest’s establishment also reflects the broader American conservation tradition — a landscape rescued from over-logging and restored over more than a century to its wild, forested character, now one of the defining natural landscapes of the Arkansas Ozarks.

Ozark National Forest spans northern and north-central Arkansas, with major access corridors along US-71 (Interstate 49), State Routes 7, 21, 23, and 74, and numerous forest roads. The Jasper, Clarksville, Russellville, and Fort Smith areas serve as gateway communities. The forest is free to enter, with fees at developed campgrounds and at Blanchard Springs Caverns. Dozens of trailheads, river accesses, campgrounds, and recreation areas serve visitors. Many forest roads are unpaved and may require high-clearance vehicles. Check the U.S. Forest Service (Ozark-St. Francis National Forests) for road conditions, trail information, and Blanchard Springs Caverns reservations.

The U.S. Forest Service manages Ozark National Forest for multiple uses, protecting its wilderness areas, streams, caves, and biodiversity while allowing compatible recreation and timber management. Visitors help by following Leave No Trace principles, protecting water quality in the clear Ozark streams, respecting wilderness-area rules (no motorized use), following cave-access regulations (critical for bat conservation), and packing out all trash in remote areas. The forest’s wilderness areas, clear streams, and recovering wildlife populations are conservation successes — sustaining them requires the care of all who visit this vast and irreplaceable Ozark resource.

Ozark National Forest’s remote wilderness areas, rugged terrain, and spring-flood rivers demand careful preparation. Check weather before backcountry trips — flash floods can rise rapidly in the narrow hollows and on Ozark rivers. Carry navigation tools (cell service is unreliable in the remote forest), bring enough food and water, and tell someone your plans. Wear sturdy footwear on the rocky, rooted trails and bluff-top overlooks. In the rivers, always wear a life jacket and check water levels before floating. Be bear-aware and store food properly. The caves are off-limits without authorization; never enter unmanaged caves alone.

Ozark National Forest is free to enter (fees at developed campgrounds and Blanchard Springs Caverns). Follow wilderness-area regulations (no motorized use, no mechanized equipment). Protect the clear streams — clean boats and gear to prevent invasive species. Follow cave-access rules; unauthorized cave entry is prohibited. Campfires must follow current restrictions (check for fire bans). Hunting and fishing require Arkansas licenses and must follow state and federal seasons. Store food in bear country. Pack out all trash. Check the U.S. Forest Service for road conditions, current rules, and Blanchard Springs Caverns reservations before visiting.

Buffalo National River flows along the forest’s northern edge; Blanchard Springs Caverns lies within the forest’s boundaries; Hawksbill Crag sits in the Upper Buffalo Wilderness. The gateway towns of Jasper, Clarksville, and Russellville provide services. Mount Magazine State Park — Arkansas’s highest point — lies to the south along the Arkansas River Valley. The Ozark Highlands Trail, one of the longest trails in the mid-South, traverses much of the forest. Ozark National Forest anchors the wild heart of the Arkansas Ozarks, a vast backcountry landscape that defines the northern tier of the state.

Float the Mulberry or Illinois River in spring when water levels are right for the best Ozark river experience — rent from an outfitter and wear a life jacket. Reserve ahead for Blanchard Springs Caverns tours, one of the finest cave experiences in the nation. Hike to Hawksbill Crag in Boxley Valley and watch for elk in the early morning. Drive the Pig Trail Scenic Byway (State Route 23) through the heart of the Boston Mountains for panoramic fall color. Bring paper maps and tell someone your plans in remote areas where cell service is absent, and always check Ozark stream levels before floating.
