Saddleback Mountain Loop is a 5.8-mile circuit from the Appalachian Trail crossing at Swift Run Gap. It follows the AT north to the blue-blazed Saddleback Mountain Trail, crosses the mountain shoulder, takes a short fire-road connector back to the AT, then returns to the same crossing. Expect roughly 1,100 feet of climbing and about 3 to 3.5 hours on the trail. The first 1.5 miles on the AT are shared with the return, so this is a wooded loop with a repeated approach rather than a separate path all the way around.
This is a good choice for a steady forest walk with some route variety. The summit itself is covered in trees, so choose it for the walk, not for a summit panorama.
