There really aren’t any balds you can camp on in the park. The closest being Gregory Bald and CS#13 (about 0.3 away). The north side of the park seems to have more reliable water supplies in the high country at least, and has some of the best views in the park from Charlies Bunion and the fire towers at Mt. Cammerer and Mt. Sterling. Here is a four day loop that will give you some great views, high elevation, lower wetter elevations, cascades, creek walks, and diverse forests. If you truly want more bald hiking, then I suggest Roan Highlands, Grayson Highlands, or Shining Rock all outside the park. The park is the best in the world for a lot of things, but balds, IMO isn’t one of them. All three listed above are better in the Southeast.
Park at Big Creek Ranger Station which is easy to access off of I-40 (Exit 451 – Waterville School Road) then hike up the Baxter Creek Trail to Mt Sterling at the Fire Tower at the top for some great views, and then follow the Mt. Sterling Ridge Trail along a flat ridge with views in both directions to the Balsam Mountain Trail and Laurel Fork Shelter. 11.4 Miles
Continue on the Balsam Mountain Trail until it reaches the Beech Gap Trail, which you take down to Round Bottom then back up the other side of the mountain and an intersection with the Hyatt Ridge Trail. Follow the Hyatt Ridge Trail until you reach the Enloe Creek Trail, which you will walk on a bridge over a beautiful section of Raven Fork and then follow Enloe Creek up to Hughes Ridge. Take the Chastain Creek Trail to the Bradley Fork trail, which you will take up to the Cabin Flats Trail and Camp at pristine Campsite #49. 19.9 miles
From CS#49 backtrack 0.6 miles on the Cabin Flats Trail to the Dry Sluice Gap Trail which you follow up to the main ridge and the AT. At this point make a side trip Sobo 0.2 miles on the AT to check out Charlies Bunion and that great view. Then head back Nobo on the AT and head through the sawteeth and great views in this rugged area. You cross several 6000 foot peaks on your way to Tricorner Knob Shelter. 16.1 Miles
From Tricorner Knob continue Nobo on the AT over Mt. Guyot then on to Low Gap and back up to Mt. Cammerer, taking the 1.2 mile round trip side trail to see the stone fire lookout and great views. Get back on the AT and continue Nobo until you reach the Chestnut Branch Trail, which takes you 2.1 miles back to the Ranger Station. 17.1 miles
