||From Crabapple Kroger in Alpharetta: Drive onto Hwy 140, going North towards Canton. Drive about 2.5 miles or so, until you cross the bridge into Cherokee Co.; take a left immediately onto Arnold Mill Road, (Hwy 140 kind of veers off to the left and it becomes Arnold Mill, or it goes up a curvy hill. You want to take the left) Once you take your left, continue down Arnold Mill for about a quarter of a mile; you'll see a neighborhood called, "Laurel Brooke". Pull into the neighborhood. Go to the 1st stop sign, take a left. Continue going straight until the next stop sign, take a right. Continue straight still, take your next right, and go all the way down into the cul-de-sac. You'll see a pagoda and a sign that says: "River Trail". Park in the cul-de-sac really close to the trail, try not to park in front of people's yards. Walk down the sidewalk, it turns into a small volleyball court. Go left of the court, you'll see the trail. Walk down it, and look near the river about half way, you'll see some boulders. Keep walking until the trail kind of dead ends. Walk down the bank, cross the river and go up hill. You'll see a massive boulder with some smaller neighboring ones.
