Out of the church parking lot, turn right and head up hill on Cooper Gap Road. Climb all the way up to Cooper Gap, and take a hard left along the forest service road along the ridge toward Hightower Gap. You eventually come screaming down a hill towards Hightower Gap, and if you kept going straight/left uphill, you'd continue on to Winding Stair. Don't do that. First time through here I missed the trail. The unmarked Hightower trail drops off the left side of the road, right inside of the turn. This is a sweet trail that drops away quickly and contains many rocks, loose rocks, just a few downed trees, roots, several stream crossings, and a sweet, fast, steep (technical) descent! Bring your Big Hit bike and hit the 10' (ft) ladder bridge drop towards the bottom end of the singletrack, which shoots off to the last side. (Easily bypassed if you have less travel.) At the bottom, continue onto the forest road, head left at the junction, and ride out through Frank D. Merril, and out the front gate to the church and your car. This is a sweet ride!
From Dahlonega, Head west out of town on HWY 9. Take a right on HWY 52, and then a right at Grizzle's Store onto Nimblewill Church Road. Take a right at the Bull Mountain sign (not Jake Mountain), and continue right up FS 28-1 all the way to Camp Frank D. Merril. Park at the white church outside of the camp gate.
