About midpoint on the Drive, the Kerr Arboretum and Nature Center sits between Honess, Spring and Coon Mountains. This interpretive complex serves as an outdoor laboratory designed to stimulate curiosity and develop awareness of the forest environment.
Facilities include a covered pavilion with exhibits, restrooms and drinking fountains. Of the three unpaved, interpretive trails, two are easy to walk and barrier free for those with physical limitations. The third trail climbs rugged Honess Mountain offering a greater physical challenge.
The arboretum and nature center is located in the Robert S. Kerr Botanical Area. This specially designated area contains a good representation of mixed pine/hardwood forests typical of the Ouachita Mountains. The forests within the botanical area are healthy, scenic, and showcase many of the species that inhabit the Ouachita Mountains.
