Logoly is Arkansas's first environmental education state park. Most of its 370 acres are a State Natural Area with unique plant species and mineral springs, set in old-growth forest, and the park works as a living laboratory for students and visitors. The visitor center has hands-on interactive exhibits, and interpreters lead programs. It is an easy day trip from Texarkana, El Dorado, Camden, Magnolia and Hope. The visitor center is open daily 8 a.m. to 5 p.m. from March through November.
