Tumbling Run shelter shelter is located about 1.1 miles north of the Old Forge picnic area and is directly on the trail. We pass this shelter during the PA AT #1 hike and have a short break here before continuing to Old Forge for lunch. There are two lean-to structures, labeled "Snoring" and "non-Snoring". There is an uncovered picnic table between the shelters, and another pavilion-covered table behind and slightly above the shelters.. There are also fire rings, clotheslines and, a short distance away there are tent sites. The privy is straight across the trail from the shelters. A marked trail leads left from the shelters, across Tumbling Run to a piped spring which was producing a steady stream of water when I was there.

I parked at the Old Forge picnic area and walked north along the trail to the shelter. From the same parking spot, I also visited the Antietam shelter.
