Ouachita National Recreation Trail: Arkansas Backpacking Guide

The Ouachita National Recreation Trail stretches 223 miles from Pinnacle Mountain State Park on the western edge of Little Rock, Arkansas, to Talimena State Park in eastern Oklahoma. It is one of the longest and most underappreciated hiking trails in the American South — a serious long trail with no crowds, crystal-clear creeks, and a mountain landscape that surprises everyone who shows up expecting flat Southern forest.

Overview

• Total length: 223 miles, Arkansas to Oklahoma
• Trailheads: Pinnacle Mountain SP (Little Rock, AR) to Talimena SP (Talihina, OK)
• Terrain: East-west ridges of the Ouachita Mountains — one of the few ranges in North America oriented east-west rather than north-south
• Difficulty: Moderate to strenuous; ridgeline sections are rocky with significant elevation change
• Permits: None required for backpacking
• Camping rules: Dispersed camping allowed; camp 50 ft from trail, 200 ft from water sources

The Ouachita Mountains

Most hikers expect Appalachian-style ridges running north-south. The Ouachitas run east-west, which means the trail traverses the ridges rather than crossing them — long, airy ridge walks with sandstone outcroppings and sweeping views on both sides. The rock is 300-million-year-old folded and compressed sandstone, striped with quartz seams that glint in the morning sun.

The trail traverses the Ouachita National Forest, which at 1.8 million acres is the largest national forest in the South. You will often walk an entire day without seeing another person.

Popular Sections

Lake Sylvia to Lake Winona — 12 miles

One of the most accessible and scenic day-hike or weekend segments near the east end of the trail. The route climbs onto Fourche Mountain for long ridge views, drops to Irons Fork Creek, and finishes at Lake Winona — a calm, clear lake perfect for swimming at the end of a hot day. Multiple Forest Service campgrounds at both ends.

Black Fork Mountain Wilderness — 10 miles

The most remote section of the trail, in the Arkansas-Oklahoma border country. No roads within miles, quartzite boulder fields, and exceptional solitude. The Black Fork Mountain area holds some of the best old-growth forest remaining in the Ouachitas.

Talimena Scenic Drive Connection (Oklahoma End)

The western end of the trail follows the crest of the Winding Stair Mountains along the Talimena National Scenic Byway. In mid-October, this stretch rivals New England for fall color. The road and trail run parallel, making it easy to day hike point-to-point with a vehicle shuttle.

Water and Navigation

Water sources are plentiful along most of the trail — springs, seeps, and clear mountain creeks. Filter or treat everything. In summer, some upper ridgeline sections can be dry — carry 3-4 liters before ascending long ridge walks.

Several creek crossings have no bridges. In spring, some are knee-deep or impassable after heavy rain. Accept wet feet as part of the experience, or bring neoprene socks and trekking poles for balance.

Deer Season Warning

Wear blaze orange during deer hunting season (approximately November through January). Most of the trail passes through national forest land open to hunting. This is not optional — hunting is active and hikers in earth tones are invisible in the understory. Check Arkansas Game and Fish Commission (agfc.com) for specific season dates before your trip.

Wildlife and Hazards

• Timber rattlesnakes and copperheads: Both present throughout the Ouachitas. Watch your footing on rocky sections and never put hands under rocks or into brush. Most snake encounters are in warm months on sunny rock outcroppings.
• Black bears: Present but rarely problematic; hang food or use a canister
• Wild hogs (feral pigs): Increasingly common; noisy and destructive to trail infrastructure, but not dangerous to hikers
• Ticks: Year-round but worst in spring and early summer; check thoroughly after every day on trail

Best Time to Go

• October to November: Best weather and peak fall foliage (late October). Deer season starts in November — have blaze orange ready.
• March to April: Spring wildflowers, creek crossings at manageable levels, dogwood in bloom. Trail can be muddy after rain.
• May to September: Hot and humid — temperatures routinely above 90°F with high humidity. Not recommended for extended backpacking; manageable for early morning day hikes.
• December to February: Cool and clear, very few people. Snow possible on upper ridges once or twice per winter. Hunting pressure drops after January.

Hot Springs Connection

Hot Springs National Park sits 30 miles south of the trail's middle section — a uniquely urban national park where historic bathhouses line Central Avenue and thermal springs bubble up at 143°F. After days on trail, soaking in a Bathhouse Row hot bath is the most civilized reward in Arkansas. Hot Springs also has excellent restaurants and good hotels at moderate prices.

Shuttle Logistics

For through-trips, arrange a vehicle shuttle between Pinnacle Mountain SP (west end near Little Rock) and Talimena SP (east end near Fort Smith/Mena). The driving distance between trailheads is about 250 miles via US-270 — the main road through the mountains. Local outfitters in Mena, AR (trail midpoint) offer shuttle services.

Getting There

The eastern trailhead at Pinnacle Mountain SP is 12 miles west of downtown Little Rock via AR-10. Little Rock Clinton National Airport has direct flights from most major cities. The western trailhead at Talimena SP is 90 minutes southeast of Fort Smith, AR. Mena, AR (midpoint) has lodging and is a convenient staging point for split trips.
