Overview
Rich Mountain is the roof of the Arkansas Ouachitas. At 2,681 feet, it is the highest point in the Arkansas section of Ouachita National Forest, sitting above the town of Mena on the ridgeline that forms the backdrop to western Arkansas. The Ouachita National Recreation Trail crosses the summit as part of its 223-mile run from Oklahoma to Little Rock, and the Mena to Rich Mountain section is the trail's most dramatic and most rewarding western stretch.
The 8-mile point-to-point from the Mena area trailheads to the Rich Mountain summit area follows the Ouachita Trail through a landscape that showcases everything distinctive about this mountain system: the east-west ridge orientation, the shortleaf pine and oak uplands, the exposed sandstone and novaculite outcrops, and the long ridge-walk character that gives the OT its particular appeal. This is not a summit scramble or a technical route; it is a high-country ridge walk that stays above 2,000 feet for much of its length.
No permit required. Dogs welcome on leash. Car shuttle between Mena trailheads and the Rich Mountain area is recommended for one-way hiking.
The Route
Miles 0 to 2.0: Mena access to the main ridge. Several trailheads along Hwy 88 (Talimena Drive) south and east of Mena provide OT access for this section. The most commonly used is a signed trailhead on Hwy 88 about 3 miles east of Mena. The trail climbs from the highway to the main ridgeline on a series of switchbacks through shortleaf pine-oak forest, gaining most of the section's lower elevation in the first 2 miles.
The ridge is reached abruptly: the pine forest opens, the wind picks up, and the Ouachita Valley spreads below in all directions. Mena is visible to the north in the valley between Rich Mountain and the parallel Fourche Mountain ridge to the north.
Miles 2.0 to 5.5: The ridgeline traverse. This is the heart of the section, a sustained ridge walk along the crest of Rich Mountain, with the Ouachita Trail following the narrow ridge top between broad views north and south. The trail surface alternates between packed dirt and exposed sandstone and novaculite outcrops. The novaculite here is the same material that made the Ouachitas a center of Native American tool production for thousands of years; ancient quarry sites are documented throughout this ridgeline, though disturbing them is prohibited by federal law.
Vegetation on the exposed ridge is open and wind-pruned: mountain pine, post oak, and blackjack oak in dense thickets with lichen-covered novaculite boulders scattered throughout. In October, the oak understory turns a vivid russet-red that contrasts with the gray-green lichen on the rocks in a color combination unique to the Ouachita ridges.
Queen Wilhelmina State Park appears around mile 5.0, where the OT crosses the park boundary and reaches the park's facilities. The lodge and picnic area are to the right; the OT continues left toward the summit.
Miles 5.5 to 8.0: Rich Mountain summit and descent. The final section climbs to the Rich Mountain summit area. The true high point (2,681 feet) is accessible via a short spur from the OT; the main trail continues along the ridge toward the eastern access points. The summit area offers unobstructed views in most directions. On very clear days, the Boston Mountains of the Ozarks are visible to the north across the Arkansas River valley.
The descent from the summit area to the eastern trailhead access points on Hwy 88 is the most direct return route for point-to-point hikers with a car shuttle.
When to Hike
March and April: The ridge is cold (temperatures often 20 to 30 degrees below the Mena valley) and windy, but the views are clear, the trail is dry, and the hardwood component of the ridge forest is just beginning to green up. Redbud bloom is visible in the valley far below.
October: Peak season. Talimena Drive is famous for fall color, and the OT's ridgeline vantage provides the best possible view of that color spread across the parallel Ouachita ridges. Mid-October weekdays are ideal. Weekends in peak color can see significant vehicle traffic on Hwy 88, though trail traffic remains modest.
May through September: Hikeable with precautions. Summer heat is less severe on the exposed ridge than in the creek bottoms, but still significant in July and August. Start by 7 AM in summer. Limited cell service occasionally available on the high ridge; download maps before leaving Mena.
November through February: Good winter hiking for prepared parties. Ice on the exposed novaculite ridge after precipitation is a real hazard; traction devices are worth carrying. The lodge at Queen Wilhelmina State Park provides shelter if conditions deteriorate.
What to Bring
The exposed ridgeline requires wind protection even in mild weather. A windbreaker or light shell is worth carrying year-round. Sun protection matters on the open ridge sections.
Many hikers carry 1.5 to 2 liters of water for this section; some springs exist off-trail near the ridge but are not reliable. Nearby water sources exist in drainages below the ridge; plan to carry enough or filter from a reliable source at the trailhead or park.
Car shuttle logistics: Mena (population 5,700) has hotels, restaurants, and a supermarket for resupply. The Visitor Center in Mena can provide current OT conditions and shuttle advice.
Trailhead Access
From Mena, AR, take Hwy 88 (Talimena Drive) east up the mountain. Trailhead pullouts are signed along the highway from the valley floor to the summit area. Queen Wilhelmina State Park is about 13 miles east of Mena on Hwy 88.
From Fort Smith, take US-71 south to Mena (about 65 miles). From Hot Springs, take US-270 west to Mena (about 80 miles, 1.5 hours).
Nearby
The Athens-Big Fork Trail (11 miles, moderate) is about 45 miles east and represents the premier backcountry wilderness route in the southern Ouachita, a natural companion to the ridge character of this OT section. The Lake Ouachita Vista Trail (4.5 miles, easy-moderate) and Crystal Mountain Trail (4 miles, easy-moderate) are accessible further east. Our checking conditions guide covers USFS and NOAA resources for weather and fire restrictions along the OT.
