Camping opportunities near Hillsborough, New Jersey typically operate on a seasonal basis from early April through mid-November, with most facilities closing during winter months. The region sits within the Piedmont Plateau at elevations between 100-500 feet, creating moderate terrain that's accessible for most campers. While summer temperatures average in the mid-80s, evenings can drop to the 60s even during peak season, requiring appropriate bedding regardless of when you visit.
What to do
Fishing and boating access: Round Valley State Park Campground offers exceptional fishing opportunities in its 2,350-acre reservoir, which is 180 feet deep and stocked with trout. "Really nice spot to camp very peaceful and quit. Gorgeous sunset, beautiful views. Really helpful people at the office," notes one camper at Round Valley Recreation Area. The reservoir's clear waters attract anglers and paddlers throughout the camping season.
Hiking on varied terrain: Multiple trail systems connect throughout the camping areas. Cheesequake State Park provides "trails that range from easy to moderate with quite a few lookout locations. The elevation of the trails is not too strenuous. While also walking the trails, people are able to come across many picnic and resting areas," according to one visitor who explored the Cheesequake State Park trails.
Seasonal water recreation: Swimming areas typically open Memorial Day through Labor Day at most parks. "In the summer, canoe, kayak, paddle boats, and row boats are available for rental. Several short (longest one is 2.5 miles) hiking trails that are fairly well-marked but can be a bit confusing at times," reports a camper who visited Turkey Swamp Park in late April.
What campers like
Secluded waterfront sites: Many campers appreciate the privacy at certain campgrounds. At Turkey Swamp Park, "Sites are in the woods and widely spaced apart to give you privacy and the feeling of being out in the Forrest. Sites are all level, very generous in size, and reasonably spaced apart for privacy," notes a recent visitor. The wooded settings create natural boundaries between camping areas.
Clean facilities with amenities: Bathroom and shower conditions vary between parks. "Bathrooms were clean and other campers were quiet making for a peaceful trip. Check in was pleasant but unfortunately, some things were closed due to covid restrictions," reported a solo tent camper at Spruce Run Recreation Area, who appreciated the well-maintained facilities.
Diverse camping options: From primitive hike-in sites to full-hookup areas, the region offers varied camping experiences. "Located just south of I78 and near the small hamlets of Clinton and Lebanon, what I love most about Round Valley SP is the fact that it has its very own eponymous fresh water reservoir," explains a camper who appreciates the access to both wilderness camping and water recreation at one location.
What you should know
Primitive camping challenges: Some campgrounds require significant effort to reach tent sites. "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, so while the hike we made was only 3 miles, it was not easy," warns one experienced camper about accessing the primitive sites at Round Valley State Park.
Weekend crowding issues: Several parks experience significant population increases Friday through Sunday. "There were a decent amount of people on Friday, but significantly more on Saturday. Park employees and park police drive around through the day. Some big groups of campers got a little rowdy at night," reports a camper who stayed at Spruce Run during a weekend in May.
Limited winter access: Most campgrounds close completely from November through March. "We go every year. It has everything the outdoorsman could ask for. Bring your bow and shoot at the hay barrels. Ice skate on the lake in the winter or just enjoy a gorgeous walk in the woods," notes a Turkey Swamp visitor, highlighting one of the few parks with winter activities even when camping isn't available.
Tips for camping with families
Playground access: Some campgrounds provide multiple play areas for children. "There are age-appropriate playgrounds both in the campground and by the office," notes a camper at Turkey Swamp Park. These designated play areas offer supervised recreation close to campsites.
Educational opportunities: Historical sites and nature programs complement many camping areas. At Washington Crossing State Park, one visitor notes it's "a quaint historical area kept green and nature friendly. Good for biking and dog walking," making it suitable for educational family outings with opportunities to connect history with outdoor recreation.
Seasonal activities: Many campgrounds offer special family-focused events during peak season. "We went on Halloween weekend and they had so much for the kids to do! Friendly staff and clean sites!" shares an enthusiastic visitor at Ringing Rocks Family Campground, highlighting how themed weekends can enhance the family camping experience.
Tips from RVers
Site selection strategies: RV campers recommend researching specific site dimensions before booking. "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," advises an RVer who stayed at Spruce Run Recreation Area, noting the importance of overhead clearance when selecting sites.
Hookup variations: Not all sites provide equal services, requiring planning for water and power needs. "Sites in Loops B-E all have pull-thru driveways. Sites are all level, very generous in size, and reasonably spaced apart for privacy," reports a camper at Turkey Swamp Park, who appreciated the well-designed RV sites with clear access routes.
Noise considerations: Highway proximity affects some camping areas, particularly for light sleepers. "The only con to this campground is it's proximity to the highway. You can hear 78, especially at night once the campground settles down," notes a camper at Spruce Run Recreation Area, highlighting how ambient noise can affect the camping experience, especially for RVers who often camp closer to access roads.
