Camping spots near Mercersburg, Pennsylvania range from primitive riverside sites to full-service RV parks at elevations between 400-1,200 feet in the Appalachian foothills. The region experiences distinct seasons with summer temperatures averaging 75-85°F, while spring and fall camping offers cooler temperatures in the 50-70°F range. Many campgrounds don't receive cell service due to the mountainous terrain, particularly in valley locations.
What to do
Fishing access: McCoys Ferry Campground offers direct Potomac River access with spacious riverside sites. "The site was very large and fairly spread out from the other sites unlike most campsites. We had a really nice view of the lake," notes one camper, though another mentions "it's worth noting that the only bathrooms were two sets of Porto potties. No sinks or showers."
Water activities: At Yogi Bear's Jellystone Park, families can enjoy multiple water features beyond traditional swimming. "There is a small creek to play in and a nice little hiking trail within the campground. Has a great water park, playground and bounce pad feature," according to one visitor. The park recently expanded its offerings, with one guest mentioning "They are finishing a lazy river which I look forward to next season."
Historical exploration: Fort Frederick State Park provides an educational component to camping trips. One visitor notes, "The fort is very cool, and exhibits are great." Another camper describes the experience: "There are some nice hot showers, they are on the opposite side of the bathroom facility but you have to bring your swimsuit because they are open air."
What campers like
Digital detox: Cowans Gap State Park Campground offers a true escape from technology. "Our first time at Cowans Gap and we loved it. 5 nights, 6 days with no cell or wifi to stress us out," writes Tom R. Another visitor confirms the off-grid nature: "You are totally off the grid as far as cell, WiFi, and TV signal. Be prepared to be out of communication during your stay."
Creek access: Twin Bridge Campground features water access that appeals to families. As one camper explains, "Our favorite campground. The most relaxing setting. Our kids love the creek and playing in and around it." The campground also offers delivery services that enhance convenience: "The concierge service here is unreal! You can get just about anything from the store delivered to your site."
Fall foliage: Caledonia State Park Campground provides exceptional seasonal experiences. "Beautiful in the fall," writes Michael W., noting "Absolutely amazing fall color on the lake and great drives surrounding." Facilities remain comfortable even in cooler months with "clean bathrooms and hot showers."
What you should know
Site spacing: Sites at many campgrounds in the region can be quite close together. At Greenbrier State Park Campground, "The sites on Dogwood are quite close together, but it still felt like camping." A visitor to Caledonia State Park noted, "Not the best spot... Every turn led to a dead end or closed gate with little to no signage pointing us toward the part of the park that was actually open."
Seasonal considerations: While peak summer season brings crowds, spring and fall offer quieter experiences. "We went to Cowans gap last full for a Halloween weekend and the children loved it. We even won the campsite decorating contest," shares one family. Another camper warns about Greenbrier State Park: "The beach by the lake is PACKED every weekend with day trippers - we avoided it since we are careful due to COVID."
Transportation needs: Facilities at many campgrounds are spread out, requiring planning. At Fort Frederick State Park, "The showers, water and bathrooms are very very far away (require a car) and outside of the gate. You're limited to portapoties as your only option near your campsite. You must bring in all your water too."
Tips for camping with families
Activity scheduling: Hagerstown/Antietam Battlefield KOA offers family-oriented programming. "Love love love this campground. Activities for the kids, diner with a great breakfast selection and subs and pizza for dinner," writes one camper, adding "At Halloween they have a great haunted house."
Budget considerations: Prices vary significantly between campgrounds, with some premium options costing more for comparable amenities. A visitor to Jellystone Park noted, "It was a nice place to stay for kids, lots to do for them. But very expensive for tent camping. I still paid nearly $100 a night."
Entertainment variety: Family-focused campgrounds offer structured activities that help during longer stays. "The kids were never bored and had so much fun. Us, as adults, were also never bored," reports one family at Jellystone Park, while another visitor appreciated that "Lots of family fun...Fall is the best at this campground with the trick or treating and haunted house."
Tips for RVers
Site selection: Sunvalley Campground provides year-round RV options with electric hookups. One camper describes it as a "Great camp ground base of the mountain and great people like the country life this is the place for you."
Site access: Several campgrounds feature narrow roads that can challenge larger rigs. A visitor to Hagerstown KOA noted, "The roads are very windy and narrow, and I can't imagine trying to maneuver a large RV in there."
Utilities management: Most campgrounds in the region offer limited full hookup sites. At Twin Bridge Campground, one RVer found workable solutions: "Big spacious sites, and a honeywagon to make things easier (there weren't any full hookup sites the I saw besides the long term spaces)."
