State Park: Bike, Birding, Camp, Fish, Hike, History, Picnic, Walk, Water Sports
Located along the Susquehanna River valley with its heavy forest cover and massive rock outcroppings, Susquehanna State Park offers a wide variety of outdoor recreational opportunities as well as historical significance. The park is home to some of the most popular mountain biking trails in Maryland and the river itself beacons fishermen and boaters alike. Susquehanna State Park also contains a very family friendly campground with traditional campsites and cabins. History buffs will be drawn to the restored Rock Run Historical Area with its working grist mill, the Archer Mansion, Jersey Toll House and the remains of the Susquehanna Tidewater Canal.
