Tumbling Run is a bouldering area in Michaux State Forest in Pennsylvania, managed by the State Department of Natural Resources. It is a cluster of boulder problems rather than a route-based climbing area, and all eight of its named routes are boulders. The climbing here runs from the low end of the V scale up to V10+. The easiest is Pine slab at V0-, and the hardest is Dark Crystal at V10+. The median grade is V4, so the area suits climbers of all levels, from those working on the basics to those pushing for harder moves. Summer is the warmest stretch for a visit. Typical averages from a nearby weather station show July highs around 81°F with lows near 62°F, while winter highs stay in the 30s and 40s. Walnut Bottom, another climbing area, is about 2.7 miles away. For mountain biking, Fegley Road and Gilbert Road are both within about 6 miles. Hammond Rocks, a climbing area, is about 6.2 miles off.
