Old Sewell Road. Hike to the end of Old Sewell Rd. It's about one mile from the gate at the end of the pavement, or, catch the Narrow Guage Trail from several locations and follow it to it's end at the Old Sewell Rd. Approximately 0.5 miles from the bridge crossing at Glade Creek the trail ends. Walk across Old Sewell Rd. to see this waterfall. It's just over 2 miles from the trailhead at Park Forest Rd 802 near the campground. Thank you Andrew Wojtanik for the info.
