🧭 Central New Jersey

Things to Do With Kids
in Central New JerseyA Somerset County parent's guide — indoor, outdoor, free and paid

We run an indoor playground in Hillsborough, which means we spend a lot of time answering this question at the front desk. This is the answer, written down.

How this list works. Every entry gets a name, a town, what it actually is and who it actually suits. We deliberately do not publish anyone else's opening hours or prices — those change constantly, and a guide that is out of date is worse than no guide at all. Every place links to its own site. Check there before you drive.

Space Play Academy is ours. It is on these lists where it belongs and described on the same terms as everything else, and it is marked so you never have to wonder.

The Short Answer

Tell us what kind of day it is

It's raining

Somewhere indoors

Play space, sports complex, arcade or a nature centre with an exhibit inside. Four options that do not care about the forecast.

Nothing to spend

The library, or the swamp

Story time at any of nine branches, or the free Environmental Education Center at Lord Stirling.

They're under three

Duke Farms or a story time

Paved trails a stroller can handle, and a room full of other one-year-olds.

You want a whole day

Duke Farms or Liberty Science Center

2,700 acres twenty minutes away, or the big science museum an hour up the road.

The List

Everywhere worth the drive

Indoors, whatever the weather is doing

The list you want when the forecast has already ruined the plan. All of these work in rain, snow and a heat wave.

The twin LED racing slides at Space Play Academy, running down into the ball pit

Space Play Academy

Hillsborough Ours

Seven indoor play zones across 5,600 square feet — ball pit, foam pit, climbing tower, slides, a soft enclosed toddler area, and pretend-play houses. Climate-controlled, so the weather outside is irrelevant.

SuitsAges 1–12, and genuinely both ends of that. Under-2s play free alongside a paid sibling.

Branchburg Sports Complex

Branchburg

A big indoor recreation centre — turf fields, basketball courts, a four-floor laser tag arena, an arcade and a multi-level indoor playground.

SuitsWide range, but the laser tag and the climbing playground land best from about 5 up.

Iron Peak Sports & Events

Hillsborough

A large indoor sports complex with a ninja course, climbing areas, a play-climb zone and a redemption arcade alongside the courts.

SuitsBetter from about 6 upward — most of it rewards kids who can already climb and chase.

Visit their site →

Sky Zone

South Plainfield

Trampoline park with a foam pit, dodgeball courts and freestyle jump time.

SuitsAbout 5 and up. Most locations run a quieter toddler session — worth asking.

Yestercades

Somerville

A retro arcade packed with cabinets and consoles from several decades, plus skee ball.

SuitsRoughly 6 and up, and a reliable hit with the parents too.

Bridgewater Commons

Bridgewater

An indoor mall, which on a February morning is a legitimate answer: somewhere warm and flat to walk a restless toddler for an hour without paying for the privilege.

SuitsAny age. Nobody's idea of an outing, but it works.

Visit their site →

Outdoors, and mostly free

Somerset County is unusually well served here, and almost none of it costs anything.

Duke Farms

Hillsborough

2,700 acres of meadow, woodland and water with paved trails running through it. Free to visit. Saturday parking passes are reserved in advance from April to October, so check before a weekend trip.

SuitsAny age. The paved loops take a stroller without a fight, which is rarer than it should be.

Environmental Education Center, Lord Stirling Park

Basking Ridge

Free county nature centre on the edge of the Great Swamp, with about nine miles of trail outside and the Great Swamp Experience exhibit inside — including a beaver lodge small children can crawl into.

SuitsToddlers upward. The indoor exhibit means a wet day is not a wasted trip.

Colonial Park

Franklin Township

685 acres with a large playground, a rose garden, paddle boats and a putting course, fronting the D&R Canal and the Millstone River. The park is free; the paddle boats and putting course are paid and seasonal.

SuitsEveryone. The playground is the draw for under-5s; the paths suit a stroller.

Downtown Somerville

Somerville

A walkable main street with outdoor film screenings, a summer concert series and classic-car cruise nights through the warmer months. Most of the programming is free.

SuitsBest with kids old enough to enjoy an evening out — though a stroller handles it fine.

Visit their site →

Farms and animals

Seasonal, so check before you drive — but a good farm morning beats almost anything else for a toddler.

Snyder's Farm

Somerset

Pick-your-own berries and flowers through the growing season.

SuitsToddlers upward — picking things and putting them in a container is close to a perfect toddler activity.

Visit their site →

Hidden Spring Lavender Farm

Skillman

A lavender farm that also runs alpaca walks.

SuitsSmall children who like animals, which is most of them.

Visit their site →

Worth the longer drive

Not local, but the two we would actually get in the car for.

Liberty Science Center

Jersey City

New Jersey's big science museum, with a planetarium and several floors of hands-on exhibits. Around an hour from Hillsborough.

SuitsWorks from about 3, but you get most out of it from 6 up. A whole day, not an afternoon.

Visit their site →

Somerset Patriots

Bridgewater

Minor-league baseball with the between-innings games, mascot races and fireworks nights that make the actual sport optional.

SuitsAny age that will sit for a while. Cheaper and far more forgiving than a major-league trip.

Free and indoors, every week

The most underrated answer to this whole question, and the only thing on this page that is free, indoors and available every single week of the year.

Somerset County Library System

Nine branches

Branches in Hillsborough, Bridgewater, Somerville, Manville, Skillman, North Plainfield, Peapack, Warren and Watchung, running story times for babies and toddlers alongside the shelves.

SuitsBabies and toddlers especially. Free, warm, indoors, and it fills a morning.
