GuideWe stayed for 10 days in a rustic cabin. Campground is well organized and clean. Tons of activities and even a hiking path. Pet friendly with small dog park. We had civil war soldiers drilling and staying the weekend we were there. Bathrooms are super clean.
GuideWe have a motorhome with no additional vehicle and two dogs, and this site couldn’t have been more perfect for us. A dog park, walking distance to most everything we wanted to see. The national park is mostly dog friendly. My husband caught a fish first day in the pond behind our site. The staff was super friendly and welcoming.
GuideOne of the best campgrounds I have stayed at so far the pond is nice and has a 1/2 mile walking path around it with trees and beaches to stop and sit dog park is big and has a place for small or large dogs there is 3 play grounds all different and all well kept
TravelerClean well kept family owned campground. Located a few miles off 81, in the country surrounded by beautiful views. It’s a mix campground of seasonal campers and short term campers. Very family oriented. Very nice off leash fenced dog park.
LegendThis place is right outside the gate of Harpers Ferry NP. We walked to the shuttle bus stop. It is a very large KOA, and was almost empty when we visited in September. The original site the gave us had a large rut and washed out spot, so we could not get level. I checked in the office and the reassigned another space that was much better. Full hook ups, nice clean shower and bathrooms, playground, pool, large dog park.
RangerGreat campground for families. Large water park that goes to 3 ft. Playgrounds, dog park, canteen, mini golf, jumping pillow, laser tag, pedal cars, gem mining are just some of the amenities. Very pricey during peak season. We did the camp & store at about $50/night.
ScoutOverall great camp ground only thing I noticed is at some of the RV sites the hook ups are in crazy spots some are In the neighboring sites area so you have to drag extensions around them. Also the pool and dog park isn’t on site you have to leave to go to it.
ScoutThis campground is far enough away from home but at the same time close enough for a weekend camping trip. Nice level spots for RVs. A pet area as well as a non-pet area. A lake with a beach, as well as being close to the AT. Close to Gettysburg as well.
RangerThis is a small campground with about half the sites being rustic electric back-in sites and the other being rustic walk-to tent sites. We stayed in the walk-to section. A lot of them are labeled "waterfront" by the park site but ours did not live up to that criteria so be aware of that. We were hoping to be truly stream-side but were not that near to it. The bathrooms were modern and clean. The park is extremely quiet and peaceful, probably one of the most remote PA state parks we've been to. The camper side was pretty full while we were the only ones on the walk-to side. We enjoyed walking the roads and little trails around the campground and seeing the old stone fireplaces/chimneys. There was a dog park area on the walk-to side which was nice. We liked it here.

After setting up camp, we went for a walk along the creek and played in the water," shares Matthew K. The campground provides easy access to over 26 miles of trails.
Historical immersion: Fort Frederick State Park Campground combines camping with colonial history. "The fort is very cool, and exhibits are great," notes Sean M. The park features a reconstructed stone fort from the 1750s, with interpretive programs during summer months.
Biking trails: McCoys Ferry Campground connects directly to the C&O Canal towpath. "The Western Maryland Rail Trail runs rite along the campground so if you like bike riding, take advantage," reports Adeline M. This 184-mile trail provides flat, car-free cycling through historic canal towns.
Secluded waterfront: Twin Bridge Campground offers creek-side sites popular with families. "Our favorite campground. The most relaxing setting. Our kids love the creek and playing in and around it," writes Jwalker. Sites along the water tend to book quickly during summer months.
Off-grid relaxation: Cowans Gap State Park Campground provides a technology-free experience. "5 nights, 6 days with no cell or wifi to stress us out. Biking, Hiking, sitting around a campfire, very nice," reports Tom R. The 42-acre lake offers swimming, fishing, and boat rentals from Memorial Day through Labor Day.
Firefly displays: Caledonia State Park Campground features a natural light show in summer. "We chose this park for the nice pool but loved the synchronous firefly show we saw in July!" shares Stephanie S. The display typically occurs in June and early July, with peak viewing around 9-11pm.
Reservation requirements: Most campgrounds in the region require advance booking. "We arrived after dark, way past the 3pm check-in time, but didn't have any trouble finding our reserved campsite. There were plenty of signs; everything is well marked," notes Sarah N. about Cowans Gap State Park.
Noise considerations: Train tracks run near several campgrounds. "The train does go through twice overnight and it is loud but still got a decent night of sleep," mentions Dalton S. about McCoys Ferry. Fort Frederick similarly has train noise that "sounds like it is two feet from your tent."
Site privacy varies: Campground layouts differ significantly. "Site Privacy: Open sites. Camper on site 13 created privacy with his trailer," notes Roger W. about McCoys Ferry. At Caledonia, "Nice big sites but the neighbors were right on top of you so it was kind of crowded."
Water activities: Yogi Bear's Jellystone Park offers extensive water features. "Multiple pools and a great little water park. Store was well stocked, they also had a ice-cream / quick food store attached to the pool area," David S. reports. The park also features a lazy river and splash pad.

Campsite selection: Choose sites based on family needs. "We arrived at site 23, a tent site. Sites 1-30 allow pets. I would recommend booking in advance if you plan on bringing your dogs," advises Sarah N. about Cowans Gap, noting that vet records weren't required for pets.
Site accessibility: Hagerstown/Antietam Battlefield KOA accommodates larger rigs but has navigation challenges. "The roads are very windy and narrow, and I can't imagine trying to maneuver a large RV in there," cautions Jen V. Consider calling ahead to discuss your specific rig requirements.
Hookup options: Electric sites are limited at some parks. "We had a great Memorial Day weekend here. The honey wagon makes the E/W sites no problem!" shares Melissa about Twin Bridge Campground, noting their convenient pump-out service.
Leveling considerations: Many sites require adjustment. "All the full hookup sites appeared very nice," notes Ross P. about Caledonia State Park, while cautioning that "some sites appeared not to have tent sites and steep parking."
