Birdsboro is a former quarry in Pennsylvania, which now hosts over 150 bolted sport climbs. This is the only sport climbing around from DC to NYC. The walls vary from slab to vertical with occasional overhangs. Some areas are north facing in the shade, and some are south facing in the sun; so this is almost a year-round destination.
