Primitive tent camping near Mercersburg, Pennsylvania centers around the Potomac River corridor and Appalachian Trail, with most sites situated at elevations between 400-500 feet. The region experiences humid summers with temperatures averaging 85°F and mild winters, making late spring and early fall optimal for camping. Several hiker-biker campsites along the C&O Canal require carrying gear on foot, with most primitive sites located within a 15-mile radius of Mercersburg.
What to do
Potomac River swimming: Jordan Junction Hiker-biker Overnight Campsite offers direct river access for cooling off during summer months. A camper notes, "Good site, has the necessities. Water, Porta p, fire pit. What else do you really need? Want to rinse off? Jump into the Potomac for a swim."
Rock climbing: The Annapolis Rock area provides single-pitch climbing routes approximately 25 miles from Mercersburg. According to a visitor, "The best part is the Annapolis Rock cliffs. they offer beautiful views and all kinds of single pitch rock climbing!"
Tubing on Antietam Creek: The gentle current makes this waterway ideal for tubing during summer months. As one camper observed, "Antietam creek is very close by and is perfect for tubing or just enjoy the river & nature from your campsite!"

What you should know
Limited parking options: At many C&O Canal sites, vehicles must remain some distance from actual campsites. A camper at Antietam Creek Campground explains, "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."
Wildlife precautions: Venomous snakes inhabit rocky areas along trails. "Be careful for the copperheads that come warm up on the rocky overlook," warns a visitor to Annapolis Rock.
Bear safety measures: Some sites provide bear poles for food storage. "There are also two bear poles. one near the beginning of the campsite trail and one closer to the spring," reports a camper at Annapolis Rock Campground.
Bathroom conditions vary: Maintenance of toilet facilities fluctuates throughout the season. "The one thing we had to complain about were the bathrooms. When we got there, they were okay, but by the 3rd night they were really gross," notes a camper at Antietam Creek Campground.
Tips for camping with families
Accessible river spots: Mulehalla offers family-friendly tent sites with adequate spacing between campers. "Tons of open spaces for tents, and sites are spaced far apart. This property also offers glamping experiences and sometimes live music. Bring the family (and the dog) to enjoy this gorgeous property."
Consider noise levels: Some campgrounds experience noise from nearby roads or railroad tracks. At Cacapon Junction Hiker-biker Overnight Campsite, a camper simply noted, "Train close by."
Check fire regulations: Fire policies vary significantly between sites. While Antietam Creek Campground permits fires, many hiker-biker sites along the C&O Canal prohibit them entirely. At Annapolis Rock, a camper mentions, "no fires, but there are two privies and a really nice spring near the campsites."
Pack for rugged terrain: Some sites require navigating steep slopes to reach water sources. "It was quite steep for my bum knees and ankles, but I saw kids easily run up and down it," explains a camper describing the path to the Potomac at Antietam Creek.
Tips from RVers
Limited RV options: Dahlgren Backpacker Campground and other primitive sites near Mercersburg don't accommodate RVs. A visitor notes, "This is a stop on the AT open only to multi-day backpackers. I've heard it is sometimes enforced."
Consider boondocking alternatives: RVers seeking primitive camping must look beyond the immediate Mercersburg area, as most nearby sites are tent-only. Portable gear that can be carried from parking areas proves essential for accessing these primitive sites.
