Overview
Little Missouri Falls is one of the most visited natural features in Ouachita National Forest and one of the most beautiful spots in Arkansas. The falls drop 15 feet over a broad, curved sandstone ledge into a deep, clear pool that is everything a natural swimming hole should be: cold, clean, and surrounded by old-growth pine forest with no development in sight.
The 2.5-mile out-and-back to the falls is the most accessible hike in the southern Ouachita. The trail is flat and well-maintained, following the Little Missouri River corridor through pines and hardwoods before arriving at the falls. The surrounding Albert Pike Recreation Area has a developed campground and picnic facilities, making this a natural base for a longer stay in the western Ouachita.
No permit required. Dogs welcome on leash. Free parking with vault toilets at the trailhead.
The Route
Miles 0 to 0.8: Trailhead to the river corridor. From the Hwy 243 trailhead, the path drops gently toward the Little Missouri River on a well-packed dirt trail. The forest here includes substantial shortleaf pine, the dominant tree of the Ouachita uplands, along with white oak, hickory, and sweetgum in the lower, wetter sections near the river. In early spring, redbuds and dogwoods bloom in the understory, and the effect against the dark pine trunks is striking.
The trail reaches the river corridor and follows the left bank upstream. The Little Missouri River at this point is a relatively narrow, clear-water stream, not the wide, murky river of the Arkansas lowlands, but a true mountain stream with bedrock pools and gravel bars. River otters have been documented in the Little Missouri drainage; look for slides on steep muddy banks near pools.
Miles 0.8 to 1.25: The falls approach. As you continue upstream, the trail narrows and the canyon walls begin to close in. The sound of the falls reaches you before you see them, a persistent roar that grows louder as the trail curves around the final bend. The falls come into view suddenly: a broad curtain of white water dropping over a tan sandstone ledge with a perfect pool below. In spring, when the river runs high after winter rains, the falls are genuinely impressive. In late summer, the flow diminishes but the pool remains swimmable.
The area immediately around the falls gets heavy foot traffic and is best enjoyed on weekday mornings or during shoulder season visits. The crowd dynamics on a summer Saturday can rival a state park beach. Spring and fall visits offer the falls at their best without the summer congestion.
Return: Retrace the same route. The slight downhill on the return makes the walk back feel easier than the outbound.
When to Hike
March through June is the strongest window. Spring flows make the falls most dramatic, the wildflower show along the river corridor is excellent in April and May, and temperatures are comfortable for the hike and the swim. March and April bring very few crowds.
July and August: The swimming hole is at peak popularity. Water temperatures in the pool stay cool (low 60s Fahrenheit) even when air temperatures reach 90. Arrive before 9 AM on summer weekends to secure parking and a spot at the pool. Insect repellent is useful for evening hours in the forested sections.
September through November: Fall in the Albert Pike area offers good color from the hardwoods in October, comfortable hiking temperatures, and far fewer people at the falls. The falls run lower than spring, but the swimming hole remains accessible through most of October.
December through February: The falls run cold and clear in winter, and the frozen splash zone around the base of the falls can create interesting ice formations in hard freezes. Swimming is not recommended. The campground closes; the day use area remains accessible.
What to Bring
Water shoes or sandals with grip are worthwhile if you plan to swim. The pool entry is over smooth, slick rock, and bare feet are uncomfortable and slippery. Bring your own drinking water; the Little Missouri River water should be treated before drinking.
Sun protection is necessary at the falls, where the open canyon allows full sun exposure on the pool area from mid-morning through afternoon. In summer, sunscreen and a hat are worth carrying even for a short trail.
Trailhead Access
The Little Missouri Falls Trailhead is on Hwy 243, approximately 2.5 miles south of Albert Pike Recreation Area and 17 miles northeast of Langley, AR. From Hot Springs, take US-70 west to Glenwood, then Hwy 84 south and Hwy 243 east to reach the area. Total drive from Hot Springs is about 1.5 hours.
From Mena, AR: take Hwy 84 north and east to Langley, then Hwy 243 east. Cell service is absent throughout the Little Missouri canyon area.
Nearby
The Athens-Big Fork Trail (11 miles, moderate) starts about 15 miles southwest near Glenwood and is the premier backcountry route in this part of the forest. The Cossatot River Trail (6 miles, easy-moderate) is about 30 miles south of Albert Pike and offers a completely different river character.
