The Ouachita Mountains are a mountain range located in the United States, primarily in Arkansas and Oklahoma. They are known for their unique east-west orientation, which is different from most mountain ranges in North America. The area features diverse ecosystems, including forests, rivers, and wildlife, making it a popular destination for outdoor activities like hiking and camping. The Ouachita National Forest covers a significant portion of the range, providing recreational opportunities and protecting the natural environment. The mountains are also home to several scenic byways, such as the Talimena Scenic Drive, which offers stunning views of the landscape, especially during the fall foliage season.
