Ouachita National Recreation Trail

The Ouachita National Recreation Trail is a 359 km (223-mile) point-to-point trail through the Ouachita Mountains of Arkansas and Oklahoma, United States, accumulating an estimated 10,500 m of cumulative elevation gain across forested ridgelines that peak at 796 m on Rich Mountain. Rated moderate to strenuous, it is the longest trail in the American South, linking Talimena State Park in Oklahoma to Pinnacle Mountain State Park in Arkansas over 14–21 days.

About the Ouachita National Recreation Trail

The Ouachita National Recreation Trail (OT) stretches 359 km (223 miles) through the rugged Ouachita Mountains, one of the oldest mountain ranges in North America. Running roughly east–west, the trail links Talimena State Park in Le Flore County, southeastern Oklahoma, to Pinnacle Mountain State Park near Little Rock, Arkansas — making it one of the premier long-distance hiking routes in the American South and a designated member of the Regional Walking Network (RWN).

Construction began in May 1971 by the Ouachita National Forest and was completed in 1981. The first documented through-hike was completed in 1983 by Jim Rawlins. Since then, the trail has attracted thru-hikers, section hikers, and weekend backpackers drawn to its solitude, biodiversity, and dramatically varied terrain.

Of the 359 km total, 285 km (177 miles) lie within Arkansas and 74 km (46 miles) cross Oklahoma. The vast majority — 309 km (192 miles) — pass through the Ouachita National Forest, while 50 km (31 miles) are maintained by Pinnacle Mountain State Park. Two federally designated wilderness areas protect the most remote sections: the Flatside Wilderness and the Upper Kiamichi River Wilderness.

The Friends of the Ouachita Trail, the trail's volunteer operator, has maintained and expanded a shelter network since 2013, adding to the 20-plus shelters that dot the route. For trail advisories, maps, and temporary closures, the Ouachita National Forest publishes up-to-date information year-round.

Packing right matters enormously on a route this long. A thorough review of the best ultralight backpacks of 2026 before you go can shave critical grams from your load — on the OT's ridgeline climbs, every saved kilogram pays dividends.

Route Overview & Stages

The trail runs west to east. Most thru-hikers start at the western terminus in Talimena State Park, Oklahoma, and finish at Pinnacle Mountain State Park near Little Rock, Arkansas. Heading east means you gain the trail's highest ground — Rich Mountain at 796 m — early on when legs are fresh. The seven stages below reflect natural resupply points and shelter clusters.

Highlights & Points of Interest

• Rich Mountain (796 m) — The highest point on the trail, located 74 km (46 miles) from the western terminus. The summit ridge runs alongside the Talimena Scenic Drive and offers sweeping panoramas across the Ouachita valley on clear days.
• Talimena State Park — The western trailhead in Le Flore County, Oklahoma, at approximately 793 m elevation. The park offers parking, a commemorative trail marker, and immediate access to the high ridgeline.
• Upper Kiamichi River Wilderness — One of two federally designated wilderness areas on the route. This 4,200-hectare zone in southeastern Oklahoma is among the least-visited wild areas in the American South, protecting clear mountain streams and rare riparian habitat.
• Flatside Wilderness — The second wilderness area, located in Perry County, Arkansas. At 4,700 hectares it offers dense hardwood forest, spectacular spring wildflower displays, and reliable water sources throughout most of the year.
• Womble Trail Junction — Near Story, Arkansas, the OT intersects the 60 km (37.8-mile) Womble Trail, which loops through the Ouachita Mountains and creates multi-day loop options for hikers not committing to the full point-to-point.
• Mount Ida Crystal Country — The town of Mount Ida, Arkansas sits in the heart of North America's premier quartz crystal mining district. Several dig-for-a-fee mines operate within a short drive of the trail, making it an unusual mid-hike cultural detour.
• Historic Big Maumelle River Bridge — A 1920s steel truss bridge near the trail's eastern end, now restricted to pedestrian use only. Crossing it over the cypress-lined Big Maumelle River is one of the route's most atmospheric moments.
• Pinnacle Mountain State Park — The eastern terminus and a dramatic finish: the 250 m basalt plug of Pinnacle Mountain rises abruptly from the Arkansas River Valley, and a short scramble to the summit rewards hikers with a panoramic view of the Little Rock skyline.

Best Time to Hike the Ouachita National Recreation Trail

October is the single best month to hike the Ouachita National Recreation Trail. Daytime temperatures across the Ouachita Mountains typically range from 15–22°C, humidity drops sharply from summer levels, autumn foliage turns gold and crimson across the hardwood ridges, and water sources remain reliable after autumn rains. As of 2026, the Friends of the Ouachita Trail reports that October records the highest thru-hiker completion rates of any month on the calendar.

Spring (March–May) is a strong alternative. Wildflowers bloom prolifically across both wilderness areas in April, and temperatures sit at 10–20°C. March can bring heavy sustained rain across Oklahoma and Arkansas alike, making the trail muddy and creek crossings deeper than usual. Water availability is excellent throughout spring.

Summer (June–September) is possible but demanding. Temperatures regularly exceed 35°C in the lower valleys, and the combined heat-humidity index makes prolonged exertion dangerous in July and August. Carry a minimum of 4 litres of water capacity and plan to start hiking well before dawn if summer dates are unavoidable. Some seasonal springs dry up between July and September, particularly on the Oklahoma sections.

Winter (November–February) offers cold solitude. Temperatures can drop below -10°C on exposed ridgelines near Rich Mountain, and snow is possible on higher sections from December through February. Ice on rocky terrain adds difficulty. In exchange, winter hikers enjoy near-complete solitude and freedom from the ticks and chiggers that are the trail's primary nuisance from April through October.

Practical Information

Accommodation

The Ouachita Trail supports a network of 20-plus three-sided Adirondack-style shelters, spaced roughly 13–24 km apart along the route. Shelters are free, first-come first-served, and cannot be reserved. Each has a fire ring and a nearby water source; several have bear boxes. Carry a tent regardless — shelters fill on peak-season weekends.

Dispersed camping is permitted throughout all Ouachita National Forest sections at no cost. Apply Leave No Trace principles: camp at least 60 m from water sources and 60 m from the trail. Developed campgrounds at road crossings include Charlton Campground (approximately €15–22/night), Fulton Branch Campground (€12–18/night), and Crystal Springs Campground (€20–28/night) — fees converted from USD at approximate 2026 exchange rates. For a town bed, Mena, Arkansas offers budget motels at roughly €60–90/night; Mount Ida, Arkansas runs €70–100/night.

Getting There & Back

Western terminus — Talimena State Park, Oklahoma: The nearest commercial airport is Fort Smith Regional Airport (FSM), approximately 100 km northeast, with connections via Dallas/Fort Worth (DFW). No public transit serves the remote Talimena trailhead; rent a car or arrange a shuttle. Several OT-specific shuttle services advertise through the Friends of the Ouachita Trail website and can position vehicles at both termini for approximately USD 150–250.

Eastern terminus — Pinnacle Mountain State Park, Arkansas: Bill and Hillary Clinton National Airport (LIT) in Little Rock is approximately 25 km east, with direct flights to Chicago, Dallas, Atlanta, and Denver. From LIT it is a 30-minute drive or 40-minute rideshare (approximately USD 25–35) to the Pinnacle Mountain trailhead at Natural Steps, Arkansas. Little Rock's Amtrak station (Texas Eagle line) is an option for travellers arriving without air.

Permits & Fees

No permit is required to hike the Ouachita National Recreation Trail as of 2026. The trail is free to hike end to end, with no quotas or reservation systems in place. The only fees you may encounter are developed campground sites (USD 12–35/night, cash or card) and a day-use parking fee at Pinnacle Mountain State Park (approximately USD 5 per vehicle). Check the Ouachita National Forest website for any temporary closures due to wildfire or storm damage before you depart.

Gear & Packing List

The OT's 359 km, multi-week demands call for a pack that balances capacity with carry weight. Most thru-hikers settle on a 40–65-litre pack. Our Best Ultralight Backpacks 2026 guide compares the leading options in detail to help you choose before committing.

• Pack: The Zpacks Arc Haul Ultra 50L is a thru-hiker favourite on long southern routes — its ultralight DCF construction handles the Ouachita's humid conditions well. The Hyperlite Mountain Gear 3400 Windrider offers superior waterproofing for Arkansas spring rain. For traditional framed comfort across 200-plus miles, the Osprey Aether 65 is a proven long-haul option.
• Footwear: Trail runners suit most thru-hikers for the full 359 km. Sturdy boots provide better ankle support on rocky ridgeline sections near Rich Mountain and through the Flatside Wilderness.
• Water treatment: A squeeze filter is essential — springs can be seasonal in summer, and giardia has been documented in Ouachita water sources.
• Insect protection: Permethrin-treated clothing and DEET repellent are non-negotiable from April through October. Ticks and chiggers are the trail's primary nuisance across this period.
• Navigation: Download the Guthook Ouachita Trail app or carry the Ouachita National Forest 1:63,360 topo maps. Trail blazes are white paint on trees and can be faded in older sections east of Lake Ouachita.
• Food: At a 25 km/day average, a thru-hike requires 14–18 days of food between resupplies. Read our guide on how many calories you need hiking a full day to size daily food weight correctly — caloric deficit compounds quickly on a multi-week southern trail.

Frequently Asked Questions

When is the best time to hike the Ouachita National Recreation Trail?

October is the single best month. Temperatures across the Ouachita Mountains settle at 15–22°C, humidity drops sharply from summer highs, autumn foliage colours the hardwood ridges, and water sources are reliable after autumn rains. Spring (March–May) is a close second, with wildflowers and mild temperatures, though March can bring sustained rain that muddies the trail. Avoid July and August unless you are experienced in heat and humidity management.

How difficult is the Ouachita National Recreation Trail?

The OT is rated moderate to strenuous overall. No technical climbing is required, but the estimated 10,500 m of cumulative elevation gain across 359 km makes it physically demanding over its full length. Rocky ridgeline sections near Rich Mountain and through the Flatside Wilderness require sure footing. Oklahoma stages are generally gentler on average; central Arkansas sections involve sharper, more frequent climbs and descents across a more dissected landscape.

How many kilometres can you hike per day on the Ouachita Trail?

Most thru-hikers average 22–28 km (14–17 miles) per day, completing the full trail in 14–21 days depending on fitness and pace. Shelter spacing — 13–24 km apart — naturally sets daily targets for those relying on the shelter network. Section hikers typically plan 16–24 km days. Fit athletes have completed the OT in under 10 days, but this requires very early starts and minimal rest and is exceptional rather than typical.

Where do you sleep on the Ouachita National Recreation Trail?

The trail has 20-plus three-sided Adirondack shelters spaced throughout its length, all free and first-come, first-served. Dispersed camping is freely permitted throughout the Ouachita National Forest sections — no permit, no fee. Developed paid campgrounds (USD 12–35/night) are accessible at several road crossings for those who want facilities. Towns including Mena and Mount Ida, Arkansas offer motels for planned rest days and resupply nights.

Do you need a permit to hike the Ouachita National Recreation Trail?

No permit is required as of 2026. The trail is free to hike end to end with no quotas or reservation systems. The only charges you may encounter are developed campground fees (USD 12–35/night) and a day-use parking fee at Pinnacle Mountain State Park (approximately USD 5 per vehicle).
