Part of the Four-State Highlands Region

Just beyond the eastern seaboard where large cities and suburbs merge into the nation’s most densely populated region, over three million acres of forested ridges, fertile farmland, streams, lakes and reservoirs form the regional landscape called the Mid-Atlantic Highlands.

The Pennsylvania Highlands is a 13-county, 1.4 million acre region that includes the populations of the Lehigh Valley, Reading, and Pottstown, and is in close proximity to the populations of the cities of Philadelphia and Harrisburg.
