Approximately 4-5 miles of hiking trails along the Chattahoochee and in the bluffs overlooking the river. Several rock overhangs to explore and opportunities to get up close to the river for fishing.
From Atlanta, take GA 400 north to Northridge exit. Turn right then take the first right onto Dunwoody Pl. Next, turn right onto Roberts Rd which will take you back over GA 400. Look for the signed park entrance on the right.
