Arkansas trails · Butterfield Hiking Trail
A 11.0-mile out-and-back in Arkansas, with 866 ft of climbing. Managed by Arkansas State Parks.
The climbing leans toward the first third: 54% of the ascent falls between mile 0.0 and mile 3.7. It gives back about 1,103 ft along the way, so it rolls rather than climbing steadily.
