What to do
Hiking the extensive trail system: Patapsco Valley State Park offers numerous trail options ranging from easy to challenging. "The hike I did was not very long but was well worth it. The trail was well marked but there was some confusion at one point on where we were supposed to go. Luckily I had an app that kept me on trail. There are some pretty cool bridges, old houses, and a waterfall," notes a visitor to Patapsco Valley State Park.
Kayaking on nearby waterways: The region provides multiple access points for water activities within short distances from campsites. A reviewer at Patapsco Valley noted, "Roland Lake in Baltimore County is a great place to kayak on the Patapsco River. Tons of wildlife, facilities, and amenities for you and your family."
Group outdoor activities: For larger gatherings, The Adventure Park at Sandy Spring offers combined camping and adventure experiences. As one reviewer mentioned, "Very convenient for before or after your time in the largest aerial challenge course in North America. Groups only - no individual campsites."
What campers like
Proximity to urban amenities: Many campers appreciate the blend of natural settings with nearby conveniences. At Leesylvania State Park, a camper shared, "This campground was so pretty. It is small, but the price and location near DC cannot be beat. It is directly on Potomac River."
Swimming opportunities: Natural swimming areas provide relief during hot summer months. A visitor to Patapsco Valley State Park reported, "We found a small river and swimming hole at the bottom of the hill off to the side opposite the cabins/park."
Diverse camping options: From basic tent sites to more equipped facilities, the region offers various accommodation types. At Marsden Tract Group Campsite, a camper described their experience: "The camp site is beautiful secluded quiet wonderful if you're looking for that extreme outdoors. No civilization, it's a good hike to get to the campsite there's no parking nearby no water no bathrooms or electricity but all in all it's beautiful."
What you should know
Weather impacts: Seasonal conditions significantly affect camping experiences and access. A camper at Patapsco Valley State Park warned, "One negative was that 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 and it was very wet even after the rain died down."
Site preparation requirements: Many locations have specific ground conditions requiring additional equipment. At Patapsco Valley, a camper advised, "The crushed stone at the sites isn't comfortable for tents, and they won't let you pitch it on the ground, so bring extra pads and alternative ways to secure the tent to the ground."
Verification of camping access: Not all locations marked as campsites actually offer camping facilities or access. A visitor to Horsepen Branch cautioned, "Nothing here no access from C&O canal. Unless someone's lost in McKee Bieshoeeer, I doubt you'll find anything. The marker shows site on or in canal. Most sites that are north of the path shown are not really there."
Tips for camping with families
Playground access: Several camping areas feature dedicated play spaces for children. A visitor to Patapsco Valley State Park recommended, "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."
Trail difficulty considerations: Parents should research trail conditions before planning hikes with children. One Patapsco Valley camper noted, "Be aware that neither the hiking trails or playground are stroller friendly."
Educational opportunities: Prince William Forest Park offers both camping and learning experiences. A visitor shared, "The PWFP rangers and website have lots of great info on the local flora & fauna. Best moths I've ever seen in my life here. This is a great place for a school overnight or scouting."
Tips from RVers
Limited RV infrastructure: Most tent camping areas near Cabin John have minimal or no facilities for recreational vehicles. Patapsco Valley State Park provides some electric hookups but lacks other RV-specific amenities.
Strict check-in policies: Plan arrival times carefully as some parks enforce rigid schedules. A Patapsco Valley camper mentioned, "This was also the first time we have ever had to wait till exactly 3pm to check in. So if you arrive early expect to wait until 3."
Parking limitations: Vehicle access varies significantly between locations. For primitive campsites, parking may be distant from actual camping areas, requiring equipment transport on foot.
