Camping near Millstone, New Jersey offers predominantly wooded sites with varying degrees of privacy across central New Jersey's low-elevation terrain between 100-400 feet. Fall camping season typically brings daytime temperatures ranging from 55-75°F with cooler nights dropping into the 40s, ideal for campfire evenings. Several campgrounds maintain their own bodies of water, from Spruce Run's 1,290-acre reservoir to Turkey Swamp's 17-acre lake, providing alternatives to the better-known Round Valley facilities.
What to do
Archery practice: Turkey Swamp Park features a dedicated archery range where visitors can practice their skills. "Bring your bow and shoot at the hay barrels," notes Patrick M., who visits annually.
Kayaking on multiple waterways: Spruce Run Recreation Area has excellent conditions for paddling with easy shore launching. "You can launch your kayak easily from the shore," explains Ruette W., who camps at the reservoir regularly. The water at Round Valley State Park Campground is particularly clear: "There is a pump for potable water and vault/pit toilets. Trails are well-kept. Definitely a great place to start with getting into backpacking and enjoying nature," shares Agbi B.
Winter recreation options: Some parks remain accessible during winter months. Turkey Swamp Park transforms seasonally, with Patrick M. noting you can "ice skate on the lake in the winter or just enjoy a gorgeous walk in the woods."
What campers like
Spacious, pull-through sites: Campers consistently praise the generous site sizes at Turkey Swamp Park. "This campground has all pull-through sites. Nicely wooded with water and electric. Sites are level and well maintained," Jean T. explains. Sites include fire pits, picnic tables, and garbage cans.
Privacy between sites: Mountainview Campground offers excellent spacing between campsites. Christina H. reports, "Our site was fully private (could not see or hear neighbors)," adding that most sites feature "thick, wooded areas" creating a sense of isolation rare in central New Jersey.
Proximity to water views: Spruce Run Recreation Area receives consistent praise for its waterfront sites. "The sites are large, many have nice mix of sun and shade. You can launch your kayak easily from the shore," describes Ruette W. Jules T. adds, "Our site was on the water and it was really nice. A duck visited us every morning."
What you should know
Hike-in requirements: Round Valley State Park Campground requires significant effort to reach campsites. Stuart K. cautions, "One interesting fact about this place—believe it or not—it is the only NJ state park that actually offers up true wilderness camping (a.k.a. primitive), which can only be accessed by hiking 3 to 6 miles." He strongly advises, "I would STRONGLY encourage anyone who thinks that it is OK to drink from the reservoir to at least use a Life Straw."
Seasonal crowds: Cheesequake State Park Campground experiences variable crowding by season. Maggie A. notes it's "a great site for those who are not avid campers. It's close to town if you forget something and it has all the facilities you may need."
Noise considerations: Several campgrounds have proximity to highways. At Spruce Run, Jules T. notes, "The only con to this campground is its proximity to the highway. You can hear 78, especially at night once the campground settles down." Similarly, Cheesequake campers report hearing the Garden State Parkway.
Tips for camping with families
Beginner-friendly locations: Cheesequake State Park offers an ideal introduction to camping. "This is a great site for those who are not avid campers. It's close to town if you forget something and it has all the facilities you may need," notes Maggie A., highlighting its accessibility for first-timers.
Playground access: Mountainview Campground maintains play areas for children. Christina H. notes the campground has "a playground for kids" among its amenities, making it suitable for families seeking basic recreation options.
Swimming opportunities: Several campgrounds offer swimming facilities during summer months. Kevin C. notes that Cheesequake State Park's "physical facilities are in good condition and are well maintained," though he cautions the campground design doesn't provide much privacy despite its disbursed layout.
Tips from RVers
Hookup accessibility: Turkey Swamp Park features accessible utility connections. Jean T. advises, "Be sure to bring extra hose because the water spigot is a distance from the electric." This park offers water and electric hookups at all sites.
Flat, level sites: Timberland Lake Campground provides level sites near attractions. Aaron E. reports, "It was a really nice size, and the kids could fish right off the dock on the back," adding it's "a nice campground that is close to Six Flags."
Surface considerations: Robyn W. cautions about Timberland Lake's site surfaces: "My biggest issue is the sand for all pull-throughs," explaining that "sand... so hard even with rugs to pull out of trailer" was challenging despite the campground's other amenities including full hookups with cable TV connections.
