Named after an early conservationist, Rothrock is blanketed with spring and summer wildflowers, plus plenty of ferns. You may even find edible berries along the way. Parts of the run are on hard-packed dirt, though most of the loop is rocky or sandy and typical of most trails in Shingletown Gap.

To run this loop, you can park at Shingletown Gap (seen here), or from the Bald Knob Ridge trailhead on Laurel Run Road. Neither restrooms nor water are available at either, though Galbraith Gap near the Tussey Ski area has vault toilets. A small stream parallels the Lower Trail, offering the option to refill if you bring a water filter or treatment tabs along.

For a slightly longer tour linking Galbraith Gap, Little Flat Fire Tower, and Shingletown Gap, check out this route instead. Both runs are equally enjoyable, though your running style may lead you to like one over the other.
