Mostly wide singletrack and doubletrack. Be courteous to hikers and joggers and control your speed as this area sees heavy traffic on weekends. Nice scenery and a good option for riding close to town.
From GA 400 southbound take Abernathy exit. Turn right on Abernathy. Travel about two miles on Abernathy to Johnsons Ferry Rd. Turn right onto Johnson's Ferry. Go past the river and turn left onto Paper Mill road, the second intersection after the river. Go about two miles and turn left into the parking lot marked by the brown Chatahoochee River Recreation Area signs.<br /><br /><br /><br />Alternate: From 285, exit Northside Drive (stay north of 285). From east, take right onto Interstate N Pky-looks like you are going into office park, but otherwise you just get back on 285. From west, left on new northside, cross 285 and stay straight into Interstate N Pky (basically u-turn). Turn into parking lot immediately after river. Make donation. Don't be fooled by number of cars-mostly hikers.
