Most campgrounds near Odenton, Maryland sit between 100-300 feet in elevation, providing milder temperatures than nearby mountain regions. The area experiences hot, humid summers with temperatures regularly exceeding 90°F from June through August. Fall camping season typically extends through October with nighttime temperatures dropping into the 40s by late season.
What to do
Hiking varied terrain: Greenbelt Park Campground offers multiple trail options with different difficulty levels. "Beautiful park with 70 miles of hiking/biking/multi use trails. There are parks on both sides of the river to explore and experience the trails. Be sure to bring/download maps," notes one camper about Patapsco Valley State Park-Hollofield Area. This extensive trail network allows day-long exploration.
Water recreation: Access to the Patapsco River provides fishing and swimming opportunities during summer months. "We enjoyed hiking the trails directly from our campsite that led us down to the Patapsco River. There is a lot of history associated with the River and the area. You can even swim in this river. Fishing looked like fun too," reports a visitor to Hollofield Area.
Family adventure activities: Beyond standard playground equipment, some campgrounds offer unique recreational options. "The KOA offers numerous family-friendly amenities including a swimming pool, jumping pillow, and outdoor chess set," while at Ramblin' Pines, visitors appreciate that "They even have a barnyard with goats" and "a pond for fishing, a pool for swimming... the kids loved the bounce pillow."
What campers like
Urban camping convenience: Sites provide nature immersion while maintaining proximity to major cities. "This is an urban oasis. Traffic can be heard but not seen. Weekdays are pretty quiet in this campground," says one camper about Greenbelt Park Campground. Another notes it's "a quiet spot in a semi-urban area" with "plenty of space between camp site clusters."
Campground accessibility: Multiple locations offer good vehicular access and site quality. "Sites were well-maintained, including lavatories. Plenty of tree cover," notes a Greenbelt camper. At Cherry Hill Park, a visitor appreciated their "premium site for seven nights. The site was perfectly level with a fire ring, grill, picnic table and table with three chairs."
Efficient DC access: Several campgrounds provide transportation connections to Washington DC. Cherry Hill Park earned praise: "Proximity to DC and surrounding areas can't be beat. Uber, Lyft, bus, shuttle. It takes about a half hour to get downtown to the monuments." Another visitor confirmed this value: "Great for camping if u want to go into Washington DC."
What you should know
Varying levels of privacy: Site spacing differs significantly between campgrounds and between loops within the same park. At Adventure Bound Washington DC, "Sites were very close. The site was part Gravel and mostly mud/grass. There was trash on site." At Patapsco Valley State Park's Hollofield Area, "The inner loop has electric but no water or sewer. The outer circle is primitive."
Reservation requirements: Most campgrounds require advance booking, especially during peak seasons. Greenbelt Park has transitioned to an online-only system: "This is a NO CASH facility which means you CANNOT pay upon arrival so you will have to do so online."
Seasonal challenges: Weather conditions impact camping experiences throughout the year. "Jellyfish take over with a vengeance" at waterfront areas in August. During rainy periods, drainage can be an issue at some campgrounds: "When it rains it really flushes through the grounds. We had a site on the lower end of the loop and our site was hard to set up as we arrived during a storm."
Tips for camping with families
Pool access restrictions: Review pool policies for children before booking if swimming is a priority. At Washington DC / Capitol KOA, "I didnt like that non potty trained kids are not allowed to swim in their pool... I could see where it would be a problem trying to explain to a 2-3 year old that they aren't allowed to go swimming especially with older siblings."
Nature exploration opportunities: Several parks offer educational features beyond typical playgrounds. Patapsco Valley State Park's Hilton Area "is perfect for keeping the kids entertained. There is a huge playground, sensory trail and nature discovery center at the entrance to the park."
Alternative entertainment: For unusual camping experiences, consider specialized sites. Pine Tree Associates allows camping at their nudist club where "camping fees include access to a large outdoor pool, an indoor pool and a hot tub." This provides a unique camping environment for families comfortable with clothing-optional recreation.
Tips from RVers
Elevation restrictions: Large vehicles must approach some parks from specific directions. When visiting Hollofield Area, "APPROACH THIS PARK ONLY FROM THE WEST IF YOUR VEHICLE IS OVER 11 FEET HIGH. (There is a 11' bridge coming east bound into this park.)"
Hookup limitations: Most campgrounds offer partial hookups, with few offering full connections. At Patapsco Valley, "There is only 20/30amp electricity and NO water or sewer- although there was a dump and a place to fill your water tank."
Site levelness varies: RV campers should bring leveling equipment. "Our site was on a mini hill," reports one camper, while others found "nice size gravel sites, some are a bit close to each other in the 'electric' loop."
