Duncan Cemetery Falls is the upper of two waterfalls found along a tributary of Holcomb Creek near the old Duncan Cemetery. This is a nice 30-foot slide, best seen in wet weather. It can be accessed by a steep bushwhack down from Three Forks Road (FR 75), a spur from Hale Ridge Road. Just below the bigger waterfall lies a scenic 10-foot drop, flanked by a cliff in a thicket.
