Unicoi Gap to Indian Grave Gap: Hiking the Appalachian Trail & Rocky Mountain Trail
Hike a challenging day hike on the Appalachian Trail in Georgia, climbing from Unicoi Gap to Rocky Mountain, dropping into the wildflower-filled Indian Grave Gap and looping back to the trailhead on the Rocky Mountain Trail.
With a just-off-the-highway trailhead and some seriously spectacular summit views, it’s no wonder that it’s one of the most popular hikes on the Appalachian Trail in Georgia. This hike treks a heart-pounding climb of Rocky Mountain, one of the most difficult AT segments in Georgia, climbing over 1,000 feet from Unicoi Gap to the Rocky Mountain summit. After catching views from the mountaintop, the hike descends to the wildflower and mountain laurel-filled Indian Grave Gap and treks through lush forest on the middle elevations of Rocky Mountain, looping back to Unicoi Gap on the Rocky Mountain Trail.
It’s a great cardio workout, with an extended, pulse-raising climb through a rocky forest. The summit offers some great campsites just off the trail. And the forest is simply beautiful, filled with fern, moss, wildflowers and trickling creeks. It’s easily one of our favorite Appalachian Trail hikes in Georgia.
Appalachian Trail and Rocky Mountain Trail loop: the hike
The hike departs the Unicoi Gap trailhead north of Helen (view maps and driving directions), passing a large boulder with a bronze plaque commemorating the Appalachian Trail. The hike follows the AT east, climbing wooden stairs to enter a boulder-filled, rocky forest. The trail begins an unwavering climb of Rocky Mountain’s western slope, climbing through a lichen and moss-filled forest dappled with sunlight and crossing several small, trickling springs.
The trail switches back through a rhododendron-filled forest at .6 mile, passing a small campsite. Through-the-tree views of the surrounding mountains emerge on trail left as the hike continues to climb elevation. Nearing the summit, the white-blazed Appalachian Trail passes an intersection with the blue-blazed Rocky Mountain Trail, the return route for this loop hike, at .85 mile.
The hike follows the Appalachian Trail southbound, making a final climb to Rocky Mountain’s peak. Large slabs of lichen-crusted rock emerge from the forest floor, and the forest begins to thin with the ever-higher elevation. The trail passes a campsite at 1.3 miles just before summiting, catching distant views of Yonah Mountain. Several trailside campsites with stone fire rings dot the mountain’s peak.
The Appalachian Trail crosses the Rocky Mountain summit, catching more photo-worthy, expansive views of rolling mountains and valleys from a wide, slab rock outcrop. The trail begins a nearly continuous descent to Indian Grave Gap, dropping elevation through a fern-filled forest by way of rustic stone and wood stairs.
Gnarly-branched mountain laurel dominate the trail as it continues its descent. The Appalachian Trail meets the gravel-paved Indian Grave Gap at 2.5 miles, having descended over 850 feet from the Rocky Mountain summit. (From the gap, the Appalachian Trail crosses the gravel road, ascending through a tunnel of mountain laurel and trailing to Tray Mountain. A side trail departs to the southwest, descending to the Andrews Cove Campground.)
This hike turns north from the gap, following Indian Grave Gap road on the blue-blazed Rocky Mountain Trail. Wildflowers flank the trail in warm-weather months, stretching high to reach the sunlight below the tall tree canopy.
The hike rolls elevation on the blue-blazed road before reaching the turnoff to the Rocky Mountain Trail at 3.15 miles. The hike turns west, veering from the road and following the blue-blazed Rocky Mountain Trail into the forest. The trail crosses several small streams, making a steady climb of Rocky Mountain’s middle elevations in a forest filled with fern, deciduous trees and leafy underbrush.
The Rocky Mountain Trail peaks at 4.25 miles, reaching a campsite and the Appalachian Trail. The hike follows the AT westbound, descending through the forest to Unicoi Gap and completing the hike at just over 5 miles.
