Ouachita National Forest

Ouachita National Forest is an outdoor recreation destination that’s located in the states of Arkansas and Oklahoma in the south-central US. This massive forest is home to one of the largest old-growth forests in the continental United States. Ouachita National Forest contains 386 named mountains, the tallest and most prominent of which is Rich Mountain (2,677 ft/816 m).

Ouachita National Forest is situated in western Arkansas and eastern Oklahoma in the US. The forest covers 2,788 sq. mi (7,221 sq. km) of land, the vast majority of which is located in Arkansas.

The Ouachita Mountains are almost entirely encompassed within the boundaries of the Ouachita National Forest. Forested rolling hills are the most distinct feature of the national forest while old growth forests dominate about 800,000 acres (323,750 ha) of land in Ouachita.

Rolling lowlands of the region give way to dry and steep slopes filled with stunted native trees. The Ouachita River runs throughout the park and the damming of the river created the reservoir known as Lake Ouachita.

There are six wilderness areas within the forest that protect a combined 65,000 acres (26,300 ha) of land. These wilderness areas are:

  • Black Fork Mountain Wilderness
  • Dry Creek Wilderness
  • Upper Kiamichi River Wilderness
  • Flatside Wilderness
  • Poteau Mountain Wilderness
  • Caney Creek Wilderness

The wilderness areas within the forest help further preserve the natural beauty of the region. Meanwhile, the forest also contains the Winding Stair Mountain National Recreation Area, which protects the Winding Stair Mountains, a subrange of the Ouachita Mountains.

Additionally, Ouachita National Forest is surrounded by other popular outdoor recreation areas. For example, Ozark-Saint Francis National Forest, Hercules Glades Wilderness, and Irish Wilderness all lie to the north of the forest.


The geological formation of the Ouachita Mountains is particularly extensive and diverse. Interestingly, the Ouachitas are an east-west trending mountain range, unlike a majority of the ranges within the United States.

This range began forming during the Paleozoic as a result of the Ouachita Fold and Thrust Belt. The range spans 220 miles (354 km) and is actually an anticlinorium whose the oldest rocks are located in the central region of the peaks.The Ouachitas continue all the way to the Black Warrior Basin where they eventually meet up with the Appalachian Mountains.

Evidence of both widespread volcanism and metamorphism are absent within the range. Instead, the range is characterized by its extensive history of folding and faulting. Quartz is abundant within the range and the forest, as is chert.

Major peaks within the national forest include Rich Mountain, Poteau Mountain, Black Fork Mountain, Petit Jean Mountain, and Blue Mountain.

Aptly named, Ouachita National Forest is mostly forested. Pine, oak, and hickory trees can be seen throughout the national forest and are present even at higher elevations.

Endemic to the state of Arkansas is the maple-leaf oak. Other endemic species include Ouachita bluet (Houstonia ouachita), Browne’s waterleaf (Hydrophyllum brownei), and Arkansas gayfeather (Liatris compacta), among others.

Within the forest lie large populations of white-tailed deer and coyotes. Many years ago, both bison and elk inhabited the region, though they have both been locally extirpated. Black bears are rarely seen in the forest, yet they do still inhabit the entire region.

The wetlands found at lower elevations in the national forest are home to numerous species of salamanders. Many of these species are also endemic to given regions within the forest.

Human History

Prior to European colonization, the forest was home to the Ouachita Tribe, which the mountains and the protected forest are named after. The name Ouachita is believed to come from the French spelling of the word Washita. The term roughly translates to mean “good hunting grounds.”

By the sixteenth century, the Indigenous people of the region were a group of farmers who lived near what is now called the Ouachita River in established huts. The first travels through the region by Europeans took place in 1541, though settlers didn’t arrive in large numbers until the 1700s.

Around this time, the Ouachita Tribe is believed to have assimilated with the Natchitoches tribe. Many descendants of the Ouachita are now enrolled members of the Caddo Nation.

The Ouachita National Forest was established in 1907, and it was originally known as Arkansas National Forest. Around a decade later, the forest was almost changed into a national park, though this new designation never materialized. The name of the forest was later changed to its current form in 1926.

Nowadays, the forest is home to a vast network of hiking, mountain biking, and horseback riding trails, which makes it a popular destination for outdoor recreation in the region.
