Susquehanna State Park
At the upper Chesapeake, wooded trails, Rock Run’s gristmill, and river access make one state park feel like several chapters.

Artwork inspired by Francis Guy
Susquehanna State Park ties natural and industrial histories together. Rock Run Historic Area includes a gristmill, while trails climb and cross the wooded slopes above the river. Deer Creek and the broad Susquehanna create different waterside experiences, and the nearby canal remnants recall a time when moving goods along this corridor required engineering as much as muscle.
Decide whether you want a hike, historic stop, or launch: the park’s areas are not the same parking destination. Deer Creek picnic and Lapidum launch areas have vehicle or boat charges, whereas a trail-focused outing may use another access point. Bring a trail map and allow for elevation change. Historic building access and demonstrations are occasional, so do not assume the mill operates whenever the gates are open.

Good to know
This park is spread across several entrances. A single central map location is not a substitute for the trailhead or launch you choose; verify that arrival before driving.
