This trail to Yonah Mountain is located between Cleveland and Helen Georgia in the Chattahoochee National Forest. The trail is a constantly rising one from the trailhead to the summit with a fairly steep >30% grade near the midpoint of the hike. However, the destination is worth it. At the top, weather permitting, the view is astounding and you’ll find it hard to match (can you see the Atlanta skyline 80 miles to the south-south-west?).
The rock face is well known as a destination for repellers and is occasionally used for training by the U.S. Army, so call 706-864-3367 to make sure you won’t interfere with their exercises.
Parking is a well marked but unpaved, gravel lot. In the parking area there is a permanent latrine-style toilet with separate male/female facilities.
The constant climbing on the trail may bore kids a little (or even wear them out), but kids (and adults) will be awed by the view.
Also, while the view is astonishing, the drop off on the rock face is as well, with no fence or railing. This is a very dangerous view and anyone at the top should take care not to get too close to the edge.
