The escarpment's scenic canyons were home for Indians of several cultures, including the Folsom culture of more than 10,000 years ago. The region's historic era began when Spanish explorer Coronado traveled across the plains in 1541. After Spanish colonies were established in New Mexico around 1600, two-way trade between Plains Indians and New Mexicans began and gradually increased. The Plains Apache acquired horses and became proficient buffalo hunters. They were displaced by the Comanche, who arrived in the early 1700s and dominated northwestern Texas, until they were finally subdued in the 1870s. During the Comanche reign, trade prospered and New Mexican buffalo hunters, known as ciboleros, and traders, known as Comancheros, were frequent visitors to this area. Las Lenguas Creek, a few miles south of the park, was a major trade area, and a site excavated on Quitaque Creek has produced artifacts indicating that it may have been a cibolero camp.

The park offers tours and educational and recreational events and programs.

Last president of the Republic of Texas Anson Jones farmed near Washington during and after his presidency. Jones named his farm "Barrington" after his Massachusetts home, Great Barrington. There he lived with wife Mary, their four children, his sister, sister-in-law, and five slaves. The family home, two slave cabins, a kitchen building, smokehouse, cotton house, and barn made up Barrington Farm. With Jones's daybook as their guide, the interpreters at Barrington Living History Farm conduct themselves much as did the earliest residents of the original farmstead. The Jones home is original; the outbuildings are replicas constructed by Texas Parks and Wildlife using Jones's own journal and drawings. Visitors to the farm can experience the sights, smells, and sounds of the 19th century. The scene is complete with heritage breeds of livestock. Interpreters, dressed in period style clothing, help visitors better understand what life was like 150 years ago. Visitors can participate in the work of the farm and become a part of the exhibit.

The farm offers demonstrations, tours, classes, educational programs, and occasional recreational and educational events (including living history events).
