Campsites near Derwood, Maryland span elevations ranging from 300 to 600 feet above sea level, positioned between the Piedmont Plateau and Coastal Plain regions. This transition zone creates variable terrain for camping, with some sites offering level ground while others feature more challenging slopes. Temperatures typically range 5-8 degrees cooler than downtown Washington DC during summer months, providing moderate relief for tent campers.
What to do
Playground access: At Lake Fairfax Campground, families find multiple play areas. "There is a huge open field where you can sometimes watch cricket games, a nice lake where you can fish... There's a water park, paddle boats, playgrounds, trails, skate park, sports fields," notes Brittany V.
Nature trails: Wooded paths allow for wildlife viewing and forest exploration. At Greenbelt Park Campground, the American Discovery Trail passes directly through the camping area. "This is an urban oasis. Traffic can be heard but not seen. Every morning birds and squirrels [are present]," reports Becky.
Water recreation: Several campgrounds offer water activities beyond swimming. A camper at Lake Fairfax mentions, "The water park was immensely enjoyed by everyone in our group, with kids ranging from 18 months old to 13 years old. Additional fee for access to the water park."
What campers like
Privacy between sites: At Little Bennett Campground, campsites maintain good separation. "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," explains Ray & Terri F.
Urban access with nature retreat: Campers appreciate the blend of natural setting with proximity to major attractions. At Greenbelt Park, a visitor noted, "Living nearby but storing my popup camper elsewhere, I often park my camper here for a few days while I pack it for a trip. It's also just nice to experience that 'getaway' feeling without being too far from home."
Natural playspaces: Patapsco Valley State Park-Hilton Area offers unique play opportunities. A camper observed, "The Hilton entrance of Patapsco Valley Park is perfect for keeping the kids entertained. There is a huge playground, sensory trail and nature discovery center at the entrance to the park."
What you should know
Bridge clearance restrictions: Pay attention to height restrictions when approaching certain campgrounds. At Patapsco Valley's Hollofield Area, a reviewer cautions, "APPROACH THIS PARK ONLY FROM THE WEST IF YOUR VEHICLE IS OVER 11 FEET HIGH. (There is an 11' bridge coming east bound into this park.)"
Tent site terrain: Many campgrounds have varied site quality for tent camping. At Bull Run Regional Park, a camper reported, "The outer loop campsites are easily more level than the center loop. If leveling perfectly is a concern you may want to call ahead and ask before commiting to the inner loop."
Seasonal operating limitations: Operating schedules vary significantly between campgrounds. Patapsco Valley State Park and Little Bennett operate from April 1 to October 30, while Lake Fairfax runs from March 22 to September 7. Greenbelt Park and Cherry Hill Park remain open year-round.

Nature discovery options: Several parks provide structured nature activities for children. At Patapsco Valley State Park-Hilton Area, a camper shared, "The nature center was closed when we visited, but the kids still enjoyed the sensory trail and playground. It's the perfect little getaway from the city."
Budget-friendly DC access: Families can save on transportation costs. At Greenbelt Park, a visitor advised, "Take the METRO if you are going into the District. There are two stations very close to camp. I spent about $10 per day on METRO versus $20-$40 on parking in the district area."
Tips from RVers
Site selection by size: Different campgrounds accommodate various RV lengths. At Ramblin' Pines, larger rigs can access full hookups. A visitor noted, "Nice large sites with friendly staff. Lots of free activities for children and it's close to home."

Cellular connectivity: Signal strength varies across campgrounds. At Little Bennett, a reviewer reported, "AT&T 5 MB/s without booster (1 bar), 8 MB/s with it (2 bars). There is no satellite coverage due to the heavy tree canopy. OTA TV was decent using an external omni antenna."
