Mount Cammerer provides one of the best views in the Smoky Mountains. The Low Gap trail head is in the Cosby Campground, so drive to the campground and park in the area designated hiker parking.
The distance from the parking lot to the intersection with the Appalachian Trail (AT) is roughly about 2.9 miles. Over the 2.9 miles, you'll start out at an elevation just below 2,200 ft and climb to about 4,200 ft where Low Gap and the AT intersect. I would rate this portion of the hike moderate to strenuous. When you get to Low Gap, you should see the sign that says 2.1 miles to Mt. Cammerer.
The rest of the hike along the AT to the Mt. Cammerer trail is a pretty easy hike. It climbs from 4,200 ft to about 4,980 ft. At about mile 1.3 you'll be at Sunup Knob. We didn't explore here because of a potential storm coming in on us.
The trail to the Cammerer firetower is about .6 miles long. It is a trail that climbs a little and drops a little, but I'd still say it is a pretty easy trail. When you arrive at the firetower, make sure you sign the guestbook inside the firetower and hope you remembered to pack your camera. You will get great views from all around the firetower.
Total time of hike: 4hrs:35mins (2:40 up, :25 at firetower, 1:30 down) A storm was going to roll in on us, so we hiked as fast as we could to beat as much of it as we could. You should probably allow 5hrs:30mins to 6hrs to do this trail round trip.
