This historic park has over 10,000 acres for year-round hiking along the Appalachian Trail. South Mountain, a ridge composed largely of resistant quartzite, posed a formidable obstacle to the early settlers until 1755 when General Edward Braddock and a young surveyor, George Washington, constructed a road over one of its passes. Greenbrier, Washington Monument and Gathland are neighboring state parks along South Mountain.

Battle of South Mountain
On September 14, 1862, the three most southern wind gaps of South Mountain were the sites of a successful delaying action fought by Confederate forces under General Robert E. Lee during their first invasion on the North. The success in holding back Union General George B. McClellan's army allowed Lee time to regroup his forces at Sharpsburg, where the Battle of Antietam occurred a few days later. For more information, see Gathland State Park.

The Appalachian Trail
The Appalachian Trail (AT) is a 2178-mile long footpath that runs from Maine to Georgia. The Appalachian Trail in Maryland runs approximately 41 miles on the Ridge of South Mountain bordering Frederick and Washington counties. The AT is marked with white painted blazes with side trails to shelters marked with blue blazes. Click here to read information about the Maryland portion of the Appalachian Trail.

Additional Appalachian Trail Resources:

Day hikers may begin excursions at various trailheads located wherever a trail intersects a road. There are overlooks within a short hike of the trailheads on Route 40, Weverton Cliff, Gathland, Route 17, or at Pen-Mar and High Rock. In some areas the terrain can be rocky and rough.

Camping is permitted at any of the six shelters or at the Dahlgren, Pogo and Annapolis ROck Backpackers' camps. Pets are permitted when on a leash. Hunting is permitted in designated areas only. Loaded weapons are not permitted on the trail or within the safety zone (150 yards from the trail).

The Potomac Appalachian Trail Club (PATC) performs volunteer trail maintenance along the entire trail in South Mountain, and along many of the side trails.

The Appalachian Trail Conference suggests these "leave-no-trace" tips when hiking on the AT:
