Located along the Susquehanna River valley with its heavy forest cover and rocky terrain, Susquehanna State Park offers a wide variety of outdoor recreational opportunities. The park is home to some of the most popular mountain biking trails in Maryland and the river itself beckons fishermen and boaters alike. Susquehanna State Park also contains a family-friendly campground with traditional campsites and cabins. History buffs will be drawn to the restored Rock Run Historic Area with its working gristmill, Carter-Archer Mansion, Jersey Toll House and the remains of the Susquehanna & Tidewater Canal.

The river offers excellent fishing opportunities, including pike, perch, and bass for shoreline anglers or boating anglers who launch from the Lapidum Boat Ramp.

Located in the Susquehanna River Valley along the eastern border of Harford County, Susquehanna State Park contains 2,651 acres of old growth forests, open fields, multiple streams, and access to the Susquehanna River itself. The park offers a wide variety of recreational opportunities as well as points of historical significance, including the historic Rock Run Mill area. Extending from Deer Creek at the north end to the Lapidum boat ramp at the south end, this park offers over 15 miles of hiking and biking trails, fishing, boating, bicycling, horseback riding, picnicking, camping, and excellent birding opportunities. It is known as the best place in Harford County, and perhaps in the state, for migrating warblers in spring and fall.

A network of trails criss-crosses the park. A section of the Mason-Dixon Trail runs along the river and an old canal bed to connect the Deer Creek area of the park with Fisherman’s Park at the Conowingo Dam to the north. This trail may appear on some maps as the Lower Susquehanna Heritage Greenways Trail, and the northern part of it may be called the Shuresville Landing Wildflower Trail. Whatever it’s called, it’s worth a walk in any season for its outstanding birding, views of the river, and views of wildflowers in spring, notably Virginia Bluebells and Dutchman’s Breeches that carpet the cliffs along the west side of the trail. Notable birds here include breeding Prothonotary Warblers and Baltimore Orioles. Winter brings a large number of Bald Eagles to the river. The trail is marked with Greenways emblems at half mile intervals. The 2.2-mile section between Conowingo Dam and Stafford Road at Deer Creek is mostly a stone-dust surface with some dirt sections, and can accommodate a wheelchair, but may be too soft after wet weather. This trail is accessible from the Deer Creek Picnic Area or Conowingo Dam parking area. A one-mile unimproved section continues south along the Susquehanna, bringing you to a trestle bridge at the mouth of Deer Creek.
