Fort Leaton State Historic Site consists of 23.4 acres, five of which are the site of a pioneer trading post. In 1848, Ben Leaton built a fortified adobe trading post known as Fort Leaton. He dominated border trade with the Apache and Comanche Indians before he died in 1851.

The park is day-use only and offers picnicking areas, guided tours, plus exhibits on the history from 15th century, natural history, and archaeological history of the area. The site serves for historical study activities.
