Think York County is just farmland Think again, because Susquehanna Riverlands State Park packs over a thousand acres of raw, green canopy right where Codorus Creek empties into the main river. It is wild. You won't find paved bike paths or concession stands selling cheap hot dogs here, but you will find rugged trails that connect directly to the 200-mile Mason-Dixon Trail. Actually, the steep climb up to the Schulls Rock overlook will sweat-test your stamina.

Bring your binoculars. Bald eagles routinely patrol the park's 1.4 miles of rocky river shoreline, hunting for catfish in the shallows. You can fish, too. Anglers wade right into the rushing water to snag smallmouth bass, especially during the humid summer months. It's noisy, muddy, and perfect. If you prefer dry land, those steep climbs up the river hills will redline your heart rate while teaching you a quick lesson about Pennsylvania's rugged geology.

There are no entrance fees or day use fees for any state park in Pennsylvania.
