Petit Jean features CCC/Rustic Style architecture that endures as a legacy to the craftsmanship and conservation achievements of the Civilian Conservation Corps. The park includes three National Historic Districts and contains more than 80 buildings, trails, and bridges. The most prominent architectural structure, Mather Lodge, stretches along the bluff of scenic Cedar Creek Canyon. The bluffs, waterfalls, and vistas of Petit Jean Mountain inspired the creation of Arkansas's first state park, and along with it Arkansas's state park system.

The site offers occasional recreational and educational events.
