The Humpback Rocks Loop Trail incorporates in the same great views, but is a 4.8 mile looped trail.
Taking the Loop Trail from the south-side (right side) of the Humpback Gap parking lot follows the same steep trail as the direct path. Offering no real advantage, it’s just a longer return.
However, consider doing the route clockwise. This avoids a lot of the congestion on the direct trail, and saves the steep section for the down-hill decent.
Find the start of the trail at the north-side (left side) of the parking lot. It’s pretty well signposted as you make your way. The path jumps from the Old Howardsville Turnpike to the Appalachian Trail, before curving up to the rock scramble for the viewpoint.
