Knoxville, Maryland sits in the shadow of South Mountain at 367 feet elevation where the Potomac River forms a boundary between Maryland and Virginia. The area experiences hot, humid summers with temperatures averaging 87°F in July and August, while winter lows can drop to 22°F in January. Campers can access over 3,000 acres of state and federal parkland within a 15-mile radius, creating numerous options for outdoor exploration year-round.
What to do
Waterfront activities on the Potomac River: Brunswick Family Campground offers direct river access with boat launch facilities. "Great location right next the river. Easy to walk into the river or tube down it. Lots of different activities for kids and plenty of space at each site to make your home away from home," shares Nicholas S., who especially enjoyed the water access.
Hiking the Appalachian Trail sections: Greenbrier State Park connects to the AT with challenging terrain. "Hike from visitor center to AT is steep and rocky," notes Butch B., highlighting the physical demands of this connection trail. The park offers trails ranging from beginner-friendly loops to more challenging uphill hikes.
Historical exploration at Antietam: Antietam Creek Campground provides a base for exploring nearby Civil War sites. "The proximity to historic Harpers Ferry (approximately 6 miles from the campsite) offers additional exploration opportunities, though parking can be challenging," one camper observed. "Small campground with a pit toilet right on the Potomac river picnic table and fire ring with a few nice trees throughout the camp area," Kevin D. explains about the minimalist camping experience.
What campers like
River views with train atmosphere: The combination of waterfront and passing trains creates a unique camping experience. "The river view was nice, but we were packed in with our neighbors like sardines and no shade," Robin explains about Brunswick Family Campground, providing a balanced perspective on the waterfront sites.
Clean facilities at state parks: Cunningham Falls State Park maintains well-kept facilities. "This campground is fantastic! Great sites and clean facilities!!" comments Ella P., emphasizing the overall maintenance of the park. "My family and I have been coming here every year since I was young and it is my absolute favorite place to camp," adds Amanda W.
Privacy between sites: Many campers value separation between campsites. "We stayed at site D72 for 4 days. The sites are quiet, very spacious, level, and heavily wooded with 50A service, water and sewer hookup," shares Ray & Terri F. about Little Bennett Campground, highlighting the privacy factor that's important for many campers.
What you should know
Bathroom facilities vary widely: Facility quality differs significantly between campgrounds. "Bathhouse had no hot water and was filthy. Guest services was non existent," reported Amy about Jellystone Park, contrasting sharply with positive reviews at state parks.
Train noise impacts some campgrounds: Several riverside campgrounds sit near active rail lines. "The river views were amazing, but face the other way and you're looking at a 15 or so foot CSX rail line berm. The trains that come through here almost hourly range from quick commuter MARC or Amtrak trains to long freight trains," explains Sherri C. about Harpers Ferry Campground, noting the trade-off between scenic views and noise.
Seasonal crowds at water features: Swimming areas become extremely crowded during summer weekends. "The beach area at the lake is PACKED every weekend with day trippers - we avoided it since we are careful due to COVID," Sarah K. noted about Greenbrier State Park, highlighting the need to plan water activities strategically.
Tips for camping with families
Water recreation options: Yogi Bear's Jellystone Park offers extensive water features. "A little hard to find, no major/large signs to tell you where to turn into the park. The entrance comes up quick and could easily be passed," notes Phibao T., providing helpful arrival information. "We recent went camping for the first time at Jellystone in Maryland. 5 of our 6 kids came with us, so we knew we needed to find a camping ground more geared kids," shares Mary.
Halloween festivities: October brings special family activities at many campgrounds. "This campground is very close to DC and lots of shopping and Clarksburg upscale outlets," notes Regina C. about Little Bennett, highlighting its strategic location for combining outdoor activities with shopping options for families.
Kid-friendly hiking trails: Choose appropriate trails based on child age and ability. "The 3-yo had no issues on the trails. The volunteer staff were awesome and extremely helpful," explains Buck P. about Cunningham Falls State Park, providing reassurance for families with young children considering hiking options.
Tips from RVers
Site leveling challenges: Some campgrounds require significant leveling equipment. "Heads up, big rig owners! Our Pull-thru FHU Patio site had a serious slope. It was impossible to level my 45' motorhome without elevating the front wheels dangerously in the air," warns Matt S. about Harpers Ferry/Civil War Battlefields KOA, highlighting an important consideration for larger RVs.
Electric hookup sharing: At certain dog friendly campgrounds near Knoxville, utility connections may require extensions. "Many sites share a power pole and water faucet, but they are well situated," explains Dale Y. about Brunswick Family Campground, noting this space-saving design feature that RVers should prepare for.
Low season availability: Off-peak camping offers more availability and quieter experiences. "It was August 1st and the bugs were minimal and there is a visitor station and aviary but I wasn't able to see them," shares Ellen C. about Cunningham Falls State Park, highlighting the benefits of late summer camping with fewer insects.
