The 193-mile, blue-blazed, long-distance Mason-Dixon Trail starts at Chadds Ford near the Delaware border. It heads south to Newark, Delaware, then enters Maryland, passing through Elk Neck State Park and crossing the Susquehanna River to Havre de Grace. The trail then follows the west bank of the river for 65 miles north to Wrightsville, Pennsylvania. In this stretch, it passes Conowingo Dam, Peach Bottom, Lock 12, Otter Creek Family Campground, Holtwood Dam, and Long Level. From Wrightsville, the trail heads west to Gifford Pinchot State Park and ends at the Appalachian Trail near Mount Holly Springs.
Hiking along backroads in Delaware and Maryland takes you past beautiful old homes, farms, and rural scenery. In York County, the river bluffs rise about 800 feet above the Susquehanna, providing spectacular views as well as aerobic exercise. Maps and a guidebook are available, along with information about the trail on their web site.
