Bear Meadows Natural Area is located in Centre County, Pennsylvania, United States, four miles south of Boalsburg, within Rothrock State Forest in the Appalachian Mountains. The area contains a bog surrounded by steep mountains and hiking trails. The bog, which covers 320 acres (130 ha), has been forming since the end of the last glacial period 10,000 years ago and is surrounded by an old-growth forest of boreal species typically found much farther north, such as black spruce, balsam fir, eastern hemlock, and yellow birch. The area was designated a National Natural Landmark in 1965.
