Formerly two separate roads with different open dates, Martin Branch Road is one through road with one set of dates that acts as a shortcut bypass of Chattahoochee River Road. This long, steep gravel road runs almost parallel to Highway 75 along the ridges and mountaintops, connecting the top of Chattahoochee River Road near Unicoi Gap to the bottom near Helen. You can see why it was once two separate roads as the terrain is quite different - the upper half is very steep, and the gravel is worn away most of the way, leaving compacted dirt and slightly rocky areas. The bottom half is not nearly as steep and has gravel almost the entire way, making this trail suitable for any stock 4x4 vehicle.
Although not ideal, a few scattered clearings could be used as campsites here and there.
This seasonal road is only open a few weeks per month, from September through December. The dates vary slightly each year. Check the dates before visiting via the Forest Service website.
