Allegheny National Forest

Allegheny National Forest, in Pennsylvania’s northwestern corner, is the state’s only national forest. Situated in the foothills of the Appalachian mountains, it has 463,000 forested acres, 42,000 non-forest acres, and 11,000 acres covered by water. Allegheny is open 24 hours a day to stargazers and visitors in general. There is a contact form here: “Very little light pollution,” said an EarthSky friend about this location.
