The South Arkansas Arboretum, located in El Dorado, Arkansas, was opened in 1965, and is Arkansas' only state park located within a city. It's a 13 acre garden which features plants found in the Arkansas West Gulf Coastal plain. Visitors will enjoy a pretty stream and small waterfall along with all of the flowering plants. There are about two miles of paved trails and nice places to stop and have a picnic.
The Arboretum is open daily, except for holidays, from dawn to dusk. Admission is free.
