Best Campgrounds near Knoxville, MD

Knoxville, Maryland sits at the convergence of multiple camping environments, with options ranging from full-service RV parks to primitive tent sites along the Potomac River. The Brunswick Family Campground offers riverside camping with boat access just minutes from town, while the Harpers Ferry/Civil War Battlefields KOA provides year-round accommodations with tent sites, RV hookups, and cabin rentals. Antietam Creek Campground in the Chesapeake and Ohio Canal National Historical Park offers more primitive camping experiences with walk-in tent sites. The region's proximity to both the Appalachian Trail and the C&O Canal Towpath creates opportunities for hikers and cyclists to access hiker-biker campsites, many featuring basic amenities like fire rings and picnic tables.

Most campgrounds in the area operate seasonally from April through October, with limited winter camping options except at the Harpers Ferry KOA. Advance reservations are strongly recommended, particularly for summer weekends when proximity to Washington DC (approximately 60 miles southeast) creates high demand. Maryland state parks like Greenbrier and Gambrill enforce alcohol prohibitions, unlike some private campgrounds. As one camper noted, "The sites are flat and dispersed with most located adjacent to the river. Each site comes with a picnic table, fire ring and grill." Cell service is generally reliable throughout the area, though coverage may be spotty in more remote sections of the Appalachian Trail corridor.

Waterfront camping locations receive consistently high ratings from visitors, with the Potomac River and nearby lakes serving as focal points for recreation. Many campgrounds feature shaded sites that provide relief during hot summer months. According to one reviewer at Gambrill State Park, "This is a very peaceful and heavily wooded park, with minimal but perfectly adequate facilities." Families appreciate the swimming beaches at Greenbrier State Park and Cunningham Falls, though these areas can become crowded on summer weekends. Historical attractions add another dimension to camping in this region, with Harpers Ferry National Historical Park, Antietam National Battlefield, and the C&O Canal providing educational opportunities within short driving distances of most campgrounds.

    Hosack Run

    Great park, not so great camp site

    We stayed at site #146 in Hosack Run. The campground itself is a small, pet friendly loop and has very nice bathrooms/showers that were very clean and appeared fairly brand new. There is a very small playground in the loop (just swings and seesaws) and Caledonia State Park itself has lots of nice hiking and history. It sits about 20 minutes outside of Gettysburg National Battlefield. The campsite itself (#146) was pretty abysmal. It is extremely small and looks like it was once the parking lot for the restrooms. You can still see the remnants of the painted yellow parking lines on the asphalt. Our small, 12 foot pop-up barely fit with just enough room for our tow vehicle. Also, your neighbor (site #144) sits right on top of you. Lastly, we stayed during a rainy Memorial Day weekend and learned that our former parking space of a campsite sits inside of a bowl in which all other campsites drains into creating a small lake around our firepit. The one plus side was that it is extremely close to the facilities. There are lots of other nice camp sites in this loop, but this was not one of them. I would choose this site again if I was extremely desperate to camp here and no other sites were available. 5 stars for the park, trails, and locale. 1 star for the campsite.

    Caledonia State Park Campground

    Great time

    Pool, campgrounds area is so great. Don’t forget the bbq place up the street, it is so good! Getting the the bathrooms from my site will be more of a challenge once the campground fills up. Showers were a tad colder than I like but once the summer comes I would t mind it, I guess?

    Finished some of the App trail from there

    Caledonia State Park Campground

    Great Park App Trail 🤌🏼

    Great Park, showers were cold and after the App Trail, A hot shower would have been awesome. Beautiful park though. My site was a little bit uneven but it looks like the park has been through an upgrade recently.

    Harpers Ferry / Civil War Battlefields KOA

    Harper’s Ferry KOA

    The sites are close together. The park was not full Mother’s Day weekend. It is a very nice park. The bathhouses were clean. The amenities were good although we didn’t utilize them. The national historic site was very close and we walked over day 1 rode our bikes day 2. The C&O canal is accessible but you must walk your bike across the lower town bridge and carry it down the stairs. This section of the trail was very good and we completed 38 miles.

    Thought the campsites were extremely close together. There were A LOT of kids and no quiet hours. Good for families. Not good for a camping camping experience.

    Happy Hills Campground

    Campground In Need of Upgrades!

    We stayed one night here (didn't even unhook from the truck).  Arrived in the rain and were leaving early the next morning, so I didn't want to disconnect.  Our gravel pad was over 6" out of level, requiring me to use leveling pads and a leveling jack to get trailer level.  All the short-term gravel sites looked like they needed some love!

    Campground is about 80% seasonal, and apparently has no housekeeping restrictions on residents - some sites were pretty full of old dead golf carts and various debris.  Not sure I would want to stay for a destination camping experience, but it was cheap and fine for a one night stay.

    I have a great spot right by the river. It is away from all noise but the flow of water. Right on the river


Guide to Knoxville

Camping near Knoxville, Maryland offers diverse terrain with elevations ranging from 250 to 1,000 feet along the border of the Blue Ridge Mountains and Potomac River Valley. Summer temperatures typically range from 70-90°F while spring and fall bring cooler weather between 45-75°F, creating ideal camping conditions from April through October. The area's unique positioning at the junction of Maryland, Virginia, and West Virginia provides access to multiple state parks and historical sites within a 30-mile radius.

What to do

Hiking to waterfalls: Cunningham Falls State Park features Maryland's largest cascading waterfall with multiple trail options. "I hate it when you go to some parks and it looks forced or man-made," notes a visitor to Houck - Cunningham Falls State Park, who appreciated the well-kept trails and natural scenery.

Historical exploration: The area offers significant Civil War history sites and heritage trails. "Harpers Ferry is a cute little historic town and the hiking is amazing, being right on the Appalachian Trail," according to a camper at Harpers Ferry / Civil War Battlefields KOA.

Water recreation: The Potomac and Shenandoah Rivers provide excellent fishing, tubing and paddling opportunities. A guest at Brunswick Family Campground described the Shenandoah as "beautifully clean, clear and cool" and noted the campground is "only an hour and 10 minutes" from Baltimore, making it convenient for weekend trips.

What campers like

Waterfront sites: Riverside camping creates popular experiences along the Potomac. At Antietam Creek Campground, "Each site has a grill, fire pit, and picnic table. I stayed at Site 11 which had its own path down to the Potomac River," shared one visitor who enjoyed direct water access.

Mountain views: The Catoctin Mountain area provides scenic vistas and forest settings. "This is a beautiful park with a lake, beach, and swimming area. Fishing is allowed. There are lots of hiking trails," explained a camper at Greenbrier State Park, who valued the natural amenities.

Spacious sites: Several campgrounds offer well-separated camping areas. According to a Little Bennett camper: "The sites are quiet, very spacious, level, and heavily wooded with 50A service, water and sewer hookup. D Loop is for RVs, A, B, C & E are tents only."

What you should know

Seasonal operations: Most campgrounds close from November through March. "We stayed in early April 2021. The first weekend open of the season," noted a visitor at Gambrill State Park, who found the park well-prepared despite being early in the camping season.

Train noise: Several riverside campgrounds are near active railroad lines. One camper explained, "Brunswick train station and depot is just a few hundred feet away and you can hear trains at all times of the night."

Reservation requirements: Weekend bookings from May through September often fill 2-3 months in advance. According to a Harpers Ferry KOA visitor: "We had to drive down and park their cars in the parking lot by the lake EARLY or you won't get a spot."

Alcohol restrictions: Maryland state parks prohibit alcohol, while private campgrounds typically allow it. A camper at Greenbrier noted: "Be aware: no alcohol in Maryland parks."

Tips for camping with families

Water parks and activities: Some campgrounds feature dedicated children's facilities. A visitor to Yogi Bear's Jellystone Park described it as "amazing in every way possible. The kids were never bored and had so much fun. Us, as adults, were also never bored."

Swimming beaches: Lake access provides popular summer recreation. "The beach area at the lake was fantastic! My kids loved it plenty of areas to grill and dogs are allowed," shared a Cunningham Falls camper, although they noted "poison ivy everywhere" around certain campsites.

Educational programs: Many parks offer ranger-led activities. "During peak season, there are nature programs going on," mentioned a camper at Cunningham Falls State Park.

Playground access: Multiple campgrounds include play equipment. According to a Brunswick camper, the site has "an amazing playground for the kids" along with basic amenities in their "little store."

Tips from RVers

Site selection: Choose locations based on rig size and hookup needs. "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," warned a Harpers Ferry KOA visitor.

Utility availability: Water and electric hookups vary significantly by campground. A Little Bennett camper detailed: "There is no satellite coverage due to the heavy tree canopy. OTA TV was descent using an external omni antenna. There is no WiFi."

Road conditions: Some campgrounds have narrow or poorly maintained access roads. At Brunswick Family Campground, a visitor noted "the road into the campground was badly in need of repair."

Cell coverage: Service varies widely throughout the region. A camper at Little Bennett reported, "AT&T 5 MB/s w/o booster (1 bar), 8 MB/s with it (2 bars)," providing useful connectivity information.
