Underdog Falls is a cluttered 25-foot waterfall found along an unnamed tributary in the upper Coleman River area. True to its name, the waterfall is hidden just out of sight in a rhododendron thicket. It lies only 300 feet from Coleman River Road (FR 54). 

To learn about more waterfalls in the Clayton area, see chapter 9 in Mark Ozboyd's "Waterfalls of Georgia" guidebook.
