Georgia Hwy 17/75 is also called Unicoi Turnpike. Cynth Creek Road runs south east off Unicoi Turnpike 1.2 miles south of the Hwy 17/75 - Us 76 split near Hiawassee, Cynth Creek road is also 16.8 miles north of downtown Helen. Cynth Creek itself, is formed by a series of feeder streams originating in the gaps between (among?) a "U" shaped line of six different "Knobs". Looked interesting enough on the topo for me to see if there are any waterfalls in there. Take Cynth Creek Road for 1.6 + miles to the end of the pavement. Look for FS Road 122, on the left.
