Tent campsites near South Mountain, Pennsylvania sit along a significant section of the Appalachian Trail, with elevations reaching 1,700 feet in areas like Annapolis Rock. Most sites remain open from April through October, closing during winter months when trails become difficult to navigate. Many campgrounds require hikes ranging from 100 feet to over 2 miles from parking areas.
What to do
Rock climbing opportunities: At Annapolis Rock Campground, climbers find numerous single-pitch routes along the cliffs. "The Annapolis Rock cliffs offer beautiful views and all kinds of single pitch rock climbing," notes Cory D., who also mentions the campsite has undergone major restoration to reverse damage from past crowds.
Water recreation access: Campers at Antietam Creek Campground enjoy direct river access for swimming, paddling and tubing. "The Potomac is mostly flat with some 'swirlies' for experienced paddlers. I also saw some people tubing," writes Michelle N., who appreciated having a dedicated path from her site down to the water.
Monument exploration: Washington Monument State Park allows visitors to climb the first completed monument to George Washington, offering panoramic views of four states on clear days. Located directly on the Appalachian Trail, the park provides both day-use facilities and tent camping options from April through October.
What campers like
Natural water sources: Dahlgren Backpacker Campground offers a year-round water source, even when bathroom facilities close for winter. "There is a basic, but clean, bathroom with showers. There is also a year-round water source," reports Sean M., noting the campground is specifically designed for AT hikers.
Live entertainment options: Mulehalla provides occasional live music events alongside camping. "This property also offers glamping experiences and sometimes live music. Bring the family (and the dog) to enjoy this gorgeous property," mentions a visitor who appreciated the well-spaced sites.
Strategic trail access: Horseshoe Bend offers a peaceful riverside stop for Appalachian Trail hikers. "Small campsite but no one else was there, so it was perfect. There is a porta potty, water pump, and picnic table. Wonderful spot on the river," reports Miranda M., highlighting the basic but functional facilities.
What you should know
Varied site spacing: Campsites range from crowded to spacious depending on location. At Mulehalla, "Tons of open spaces for tents, and sites are spaced far apart," while at Antietam Creek, "All the sites are very open and run along the multi-use trail. People are constantly walking, running, and biking by."
Wildlife encounters: Snake sightings occur regularly at elevated sites near rock outcroppings. "Be careful for the copperheads that come warm up on the rocky overlook," warns Sy A. about Annapolis Rock Campground.
Train noise disruptions: Railroad tracks near several campgrounds create significant noise issues. "It depends on what you're looking for—easy camping and proximity to Antietam and Harper's? Golden. Especially if you want to camp but also do site seeing and/or paddling in the area," notes Andrew M., who found the location convenient despite limited privacy.
Tips for camping with families
Multi-use areas: Many sites provide recreational options beyond hiking. At Antietam Creek, "It is nice being so close to cool historical stuff. The river is beautiful," reports Casey L., though they caution about bathroom maintenance issues after multiple days.
Glamping alternatives: For families wanting comfort without full RV setups, Mulehalla offers prepared glamping accommodations alongside traditional tent sites. Their family-friendly environment welcomes pets and provides firewood on-site.
Bathroom considerations: Facilities vary widely between campgrounds. "There's one bathroom area- 2 pit toilets and 2 portapotties. There is nowhere to leave trash, so be sure to follow Leave No Trace principles and pack everything out with you," advises Michelle N. about campground sanitation expectations.
Tips from RVers
Limited RV accommodations: South Mountain area campgrounds primarily serve tent campers and hikers rather than RVs. Most sites require walk-ins from parking areas, with distances ranging from 75 feet to over a mile.
Parking logistics: At Antietam Creek, "You have to park on the road and walk about 75 feet to your site. Not much traffic on that road and a trail with many cyclists and runners," explains Nick C., noting this arrangement can create challenges for those with substantial gear.
Supply management: With limited facilities, campers must carefully plan provisions. "You have to park on the opposite side of the canal and walk to your campsite. If you got one close to the bridge over the canal then you're 100ft from the car, but if not then it could be a little bit of a walk," shares Andrew M. about the potentially lengthy carry distance.
