The Appalachian Mountains cross the Schuylkill River at the border of Berks and Schuylkill Counties. The Blue Mountains are the southernmost formation of the Appalachians and are part of the larger Kittatinny Ridge that extends into northern New Jersey. This region is known for its vast woodlands, small towns and villages, and is home to Hawk Mountain Sanctuary and the Appalachian Trail. Historically, the lush valleys of this region have been home to generations of Pennsylvania Dutch farmers. Visitors can experience the unique spiritual and artistic traditions of these German settlers by driving the “Hex Highway” along the southern edge of the ridge.

The Blue Mountains are also part of one of the most important flyways for migratory birds and provided birders unparalleled opportunities to view birds of prey during their annual migration.
