Trail Description Written by Caroline Sullivan

Low Gap Trail is the most popular route to reach the Mount Cammerer fire tower from Cosby, TN. The first 2.9 miles north of the Appalachian Trail follow Cosby Creek before breaking into a steep ascent.

The trail begins pleasantly for the first mile and winds over Cosby Creek a couple of times with some pretty, bridged crossings. There are several opportunities within this stretch to access the water, making it a popular area for nearby campers to find a place to relax.

The final two miles of the Cosby side of Low Gap trail are very steep with several very menacing switchbacks. Most hikers rate it on the more strenuous side of moderate.

The trail intersects with the AT after 2.9 miles from the campground. If you continue straight, you'll descend down the the remaining 2.5 miles of Low Gap trail before reaching Big Creek Trail 5.1 miles southwest from the Big Creek Campground. If you turn left, you'll find yourself en route to Mt. Cammerer. If you turn right on the AT, you'll be heading toward Camel Gap, Inadu Knob, and Mount Guyot.
