Camping areas surrounding Greencastle, Pennsylvania extend into three states - Pennsylvania, Maryland, and West Virginia. Located in Franklin County at elevations between 600-800 feet, this region experiences four distinct seasons with summer highs around 85°F and winter lows often below freezing. The area's combination of mountain terrain and valley sites creates diverse camping conditions, with waterfront opportunities along Conococheague Creek and mountain sites in the Catoctin range.
What to do
Hiking trails: At Caledonia State Park Campground, campers can access numerous trail options including portions of the Appalachian Trail. "We enjoyed our stay here very much. The trails were very enjoyable and we hiked about 15 miles with sections of the Appalachian trail," reports one visitor. The park maintains multiple difficulty levels of trails for different hiking abilities.
Water activities: Cowans Gap State Park Campground offers swimming, fishing, and boating on its lake. The park features a beach area with changing facilities. "Nice lake area with beach, beach house, watercraft rentals, friendly park rangers & staff, and in the center of trails galore!" notes a reviewer who appreciates the water recreation options.
Historical exploration: The Greencastle area sits within 30 minutes of multiple Civil War battlefields. Gettysburg is approximately 32 miles northeast, while Antietam Battlefield lies just 17 miles south. "We used this as our home base for exploring Harpers Ferry and Antietam. After camping a week on the beach, our stop here was a godsend," comments a camper who stayed at Owens Creek Campground while touring historical sites.
What campers like
Creek access: Twin Bridge Campground receives consistent praise for its stream-side sites. "We had Site C, which was right on the stream. This was a very nice site and we had more space between us than others had," shares one camper. The creek provides both recreation and a natural atmosphere.
Mountain setting: The wooded environment at Owens Creek Campground creates a secluded feel that campers appreciate. "Nice small campground WAY back in woods. Been here many times over the last 25 years," writes one regular visitor. The mountainous setting offers cooler temperatures and more privacy than valley campgrounds.
Family activities: Organized events for children are available at several campgrounds in the area. "We had a great Memorial Day weekend here — it was our first visit and we didn't know what to expect. This is the campground to come to with kids! If you're looking for activities and fun and friendliness this is the spot," notes a Twin Bridge camper, highlighting the family orientation of many facilities in the region.
What you should know
Site spacing varies: Campgrounds near Greencastle differ significantly in how close sites are placed. "The sites varied. Some were in an open field, others by the stream with trees," explains a Twin Bridge visitor. Campers seeking privacy should research specific loops or site numbers before booking.
Seasonal considerations: Weather impacts camping conditions from April through October. "It rained most of the weekend, but we still had a blast! The trail to the lake is accessible but far enough that you avoid the high day use traffic," reports a Cunningham Falls State Park visitor. Spring camping often deals with muddy conditions while summer weekends face higher temperatures and crowds.
Reservation requirements: Most campgrounds in the region require advance booking, particularly for premium sites. "I was advised it normally sells out on weekends, so securing a site in advance is wise," notes a Cunningham Falls visitor. Waterfront sites at places like Twin Bridge and creek-side spots at Caledonia typically book 3-6 months in advance for summer weekends.
Tips for camping with families
Water features for kids: Campgrounds with swimming areas provide built-in entertainment. "The beach area at the lake was fantastic! My kids loved it plenty of areas to grill and dogs are allowed. Most of the time we did not spend at the campsite so we ended up having a fantastic weekend," explains a Cunningham Falls visitor.
Playgrounds and activities: Hagerstown/Antietam Battlefield KOA offers structured recreation for children. "Lots of family fun. We have stayed in the camping cabins here multiple times. We love the animals and activities for the kids. Fall is the best at this campground with the trick or treating and haunted house," writes one repeat visitor.
Bathroom proximity: When camping with children, consider sites close to restrooms. "The bathhouse was also very nice and very clean. Electric outlets are a plus," notes a camper from Owens Creek, highlighting the convenience of modern facilities. Most campgrounds in the region maintain centrally located bathhouses within each camping loop.
Tips from RVers
Hookup availability: Electric and water connections vary across campgrounds. "Took our new Fifth Wheel for a shakedown trip and decided to try Twin Bridges Campground. 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)," reports an RVer who appreciated the pump-out service.
Road access challenges: Some campgrounds have narrow, winding access roads that challenge larger rigs. "We stayed in site #55. Big site but hard to get into. There are a couple of pull thru sites that are much easier," notes a visitor at Gettysburg Battlefield KOA who managed their big rig but found maneuvering difficult.
Level sites: Finding flat parking for RVs matters in this hilly region. "Very nice campground with clean bathrooms and showers. Nice small lake within walking distance along with a beach. There is also a few hiking trails near the campground," writes a camper at Cowans Gap State Park, where the paved sites are more level than many natural surfaces found elsewhere in the region.
