What to do
Fishing opportunities: 1-2 miles from campsites. At Camp Carr Campground, river fishing is accessible directly from waterfront sites. One camper noted, "I live 15 miles from this campground and have paddled by it over 50 times... Excellent view of the South Branch and extremely relaxing."
Whitewater rafting: Seasonal releases. Tohickon Valley County Park offers scheduled dam releases upstream that create "world class whitewater rafting" conditions. These typically occur in March and early November when many paddlers stay at the park cabins and campground.
Rock exploration: 10-minute drive. Unique geological features await at Ringing Rocks Park near Upper Black Eddy. A visitor to a nearby campground shared: "Went to Ringing Rocks county park and the kids were having so much fun making music they didn't want to leave." Bring a hammer to tap the rocks and hear their metallic sounds.
Observatory access: Evening programs. Voorhees State Park offers astronomy programs at their on-site observatory. The facility hosts public viewing nights where visitors can observe stars and planets through telescopes under dark skies away from city light pollution.
What campers like
Paddle-in camping experiences: 3-6 mile water route. Round Valley State Park Campground offers a unique camping experience for boaters. As one visitor described, "we paddled in, the water is very clean and crystal clear." Another camper added, "If you're looking for a getaway without doing backcountry planning this is the place."
Family-friendly amenities: Pools and playgrounds. Colonial Woods Family Resort provides extensive recreation options. A camper shared: "The pool and splash pool for toddlers was clean with a lifeguard on duty at all times." Another visitor mentioned the "playground, lake where you could fish, cornhole, and minigolf."
Quiet weekday camping: Less crowded Monday-Thursday. Several campgrounds offer a more peaceful experience midweek. A camper at Spruce Run Recreation Area reported: "Stayed here 2 nights in May, Friday-Sunday. There were a decent amount of people on Friday, but significantly more on Saturday."
Proximity to historic sites: Day trip options. Washington Crossing State Park provides access to Revolutionary War history. One visitor commented, "Every year, they re-enact Washington's troops crossing the Delaware!" The park's location offers easy access to both Pennsylvania and New Jersey historic sites.
What you should know
Campsite access challenges: Boat or hike required at some locations. Round Valley requires physical effort to reach sites. A camper advised: "The hike is a 3 mile minimum 6 max. I have hiked throughout the entire US and consider myself somewhere between a moderate to skilled hiker and I found these trails challenging and uneven."
Seasonal limitations: Most facilities close October 31. The majority of campgrounds in the area operate from April through October. Only a limited number of campgrounds remain open year-round, including Jugtown Mountain Campsites, which offers winter camping options.
Bathroom facility variations: Plan accordingly. Quality and availability of facilities varies widely. A Spruce Run camper reported: "The bathrooms were absolutely disgusting... for the entire weekend, someone's #2 remained all over the toilet, floor, and corner wall." Conversely, Colonial Woods earned praise: "The bath house with showers was clean."
Water sources: Not always reliable. Water pressure and availability fluctuate seasonally. One camper at Jugtown Mountain noted: "There was some issue with the water pressure during the daytime. Only had 1psi of water pressure. Couldn't take a shower or wash dishes. Should have filled my tank."
Tips for camping with families
Check activity schedules: Weekend programming varies. Mountainview Campground and other facilities offer seasonal events. A Colonial Woods visitor shared: "They did a few activities - the one we did go to was the casino night where they had separate play areas for kids and adults. All the money made is donated to Shriners Children's Hospital."
Consider noise levels: Highway sounds affect some sites. Spruce Run Recreation Area sits near Interstate 78. A camper noted: "The one downside to this campground is it's proximity to the highway. You can hear 78, especially at night once the campground settles down."
Select sites strategically: Water access varies. Waterfront sites offer recreational advantages but may be farther from facilities. One Spruce Run camper advised: "While it's obviously busier, we liked being below the pool where our kids could fish in the pond and easy access to the pool."
Pack extra water supplies: Limited availability at primitive sites. At some parks, water access is restricted. A visitor to Tohickon Valley County Park suggested: "Bring your own water as none is available onsite."
Tips from RVers
Site surface considerations: Materials vary by campground. Colonial Woods uses stone surfaces throughout their property. One RVer noted: "For whatever reason the sites are all covered in stone, and I don't mean just the area where you park, I mean it was like camping on a stone driveway."
Power options: Limited at some campgrounds. Spruce Run offers some sites with hookups. A camper explained: "I can not speak to the condition of the bathrooms, I stopped going into them 6 years ago as soon as I bought a cassette toilet to avoid them... We luckily have some solar so we can go for awhile without running the generator."
Road access challenges: Narrow entrances at older facilities. Some campgrounds present navigation difficulties. An RVer at Colonial Woods warned: "The roads are very narrow, pretty sizable boulders on both sides, trees are very low and need to be trimmed (almost took my ac out with a huge limb)."
Tree clearance issues: Check site descriptions carefully. Spruce Run Recreation Area has varying levels of overhead clearance. A camper advised: "If bringing your RV, the safest bet is to reserve a spot with no shade as the other spots often times have very low hanging tree limbs."
