Appalachian Trail in Maryland
Maryland’s nearly 40-mile Appalachian Trail section follows South Mountain, making ridge walks and overnight trips accessible from several road crossings.

Artwork inspired by John Ross Key
The Appalachian Trail passes through Maryland along South Mountain for roughly 40 miles. It is tempting to think of this as a short state crossing, but the landscape changes with every gap: wooded ridges, rock outcrops, Civil War terrain, shelters, and periodic views. Washington Monument State Park is a useful first access point, where a short approach joins the white-blazed route near a stone tower.
For a day hike, choose an out-and-back based on daylight and footing rather than treating the section as one attraction. For an overnight walk, use the official map and designated camping locations; this card’s map opens the Washington Monument access point, not an imaginary center of the trail. The trail is foot-only, and state-park parking may carry a day-use charge.
