Seneca Creek State Park

The 6,300-acre park extends along 14 miles of Seneca Creek, featuring woodlands, open fields, and waterways that support local wildlife populations.

Established in 1958, the park expanded through land acquisitions from 1965 to 1968, with development of camping and recreational facilities beginning in 1966.

The restored 19th-century Seneca Schoolhouse within the park served the children of local quarry workers who shaped the region's development.

The park maintains 50 miles of trails for hiking, mountain biking, and horseback riding, with seasonal hours from March to October 8:00 to sunset.

The Seneca Quarry, which provided red sandstone for the Smithsonian Castle construction in 1837, remains preserved within the park grounds.
