From Atlanta, head north on I-75 and get off at exit 267B toward Marietta. Make a right on Cobb Parkway/Ga 3 and head north for approximately 9.5 miles. Make a left on Mars Hill Rd. Continue 1.5 miles until you make a right on County Line Rd/Old Stilesboro Rd. After about 2 miles, make a sharp right on Pitner Rd. Go about 1 mile up Pitner and park at the entrance to the Pitner Rd Dog Park. The trailhead is right next to the playground.
Excellent trails for running.
