The horses are no longer thundering around the property, but this sprawling landscape still gives visitors plenty of room to roam.
Before becoming public parkland, this New Jersey property was connected to the world of thoroughbred horse racing.
Today, its hundreds of acres have been transformed into a much quieter playground of meadows, woods, trails, recreational areas, and scenic open space.
That change of pace is part of what makes the place interesting.
A landscape once shaped around a private estate and horses now belongs to hikers, families, runners, cyclists, and anyone who simply needs a patch of green for an afternoon.
There is plenty of room to spread out, too. At 667 acres, this isn’t the sort of park you accidentally finish exploring in twenty minutes.
Bring walking shoes. The old estate has become one very big backyard.
From Racehorses to Rolling Meadows
Horses came first here, and the land still seems to remember it. Long before the paved paths and picnic tables, this property was Brookdale Farm, one of the best-known Thoroughbred breeding and training operations in the region.
Racehorses were raised, trained, and cared for across these same fields.
Today, Thompson Park covers about 667 acres and serves as the headquarters of the Monmouth County Park System. The core of the park came from a generous gift of farmland left to Monmouth County by the family who last owned the estate.
That single decision turned a private horse farm into a place anyone can enjoy.
Brookdale Farm is now listed on the National Register of Historic Places as a historic district. It is considered the most complete nineteenth-century horse estate left in the county, which is a pretty big deal.
Keep an eye out for old barns and outbuildings as you explore, since many of them date back to the farm years.
Honestly, that mix of history and open space is what makes a visit here feel so special.
A Mansion That Rose Again
Big white columns, a sweeping front lawn, and tall shade trees give the Visitor Center a grand first impression. It looks like it has stood untouched for over a century.
The truth is a little more dramatic.
The original Colonial Revival mansion was built in the 1890s as the family home on the estate. In 2006, a fire destroyed the building.
Instead of letting it go, the county rebuilt it in the same historic style, and it reopened in 2009.
These days, the mansion works as the main welcome spot for the park. Inside, there are exhibits that explain the history of Brookdale Farm and the families and horses connected to it.
You can also find indoor restrooms and vending machines, which come in handy after a long walk.
My tip is to start your visit here. Grab a trail map, ask the friendly desk staff about current programs, and take a few minutes with the displays.
Knowing the backstory makes every barn and meadow you pass later feel much more meaningful. The lawn out front is lovely for a quick rest, too.
The Stable Where a Derby Legend Lived
Regret made history in 1915 as the first filly ever to win the Kentucky Derby. What surprises many visitors is that this champion has ties to the racing stable right here in the park.
Pretty cool, right?
The Historic Racing Stable is a forty-stall building and one of the most recognizable structures from the Brookdale Farm days. After a careful restoration, it opened to the public for tours.
The old wooden stalls now hold exhibits that tell the story of Thoroughbred racing and the people and animals behind it.
Historic interpreters are often there to answer questions and share details you would never find on a sign. Kids tend to love peeking into the stalls and picturing a horse standing inside.
Adults usually end up just as curious.
Since tour times can change by season, check the park schedule before you go. Even if you only see the outside, the long barn with its classic design is worth a slow look.
It is easy to imagine the sound of hooves on the floor and trainers moving from stall to stall at sunrise.
Miles of Trails for Every Kind of Mood
Choosing a trail here is a little like picking ice cream flavors. Thompson Park has around 14 miles of multi-use trails, and each one has its own personality.
Some are smooth and paved, while others wind through woods and wetlands.
The Thompson Loop is the big paved route, stretching about 4.2 miles through the heart of the park and along its northern edge. Bikers, joggers, stroller pushers, and even roller skaters love it because the ground stays fairly flat.
For something shorter, the 1.2-mile Inner Loop links the playground with Marlu Lake.
Craving dirt under your shoes? The Marshy Walk uses boardwalks to carry you over soggy wetland spots, and the Woodland Trail offers a quick trip into the trees.
The shaded Track Loop, about a mile long, is a favorite for runners.
Hikers looking for a longer outing can tackle the Reservoir Loop, roughly 4.8 miles around the Swimming River Reservoir and Marlu Lake. Some turns can be tricky, so bring a map and watch the trail markers.
Sturdy shoes and a walking stick help on the rougher stretches.
Quiet Water at Marlu Lake
Glassy and calm, Marlu Lake is the spot to visit when you want the world to get a bit quieter. This 21-acre lake mirrors the trees around it, especially on still mornings and during the colorful fall season.
Its peaceful vibe is hard to beat.
Anglers can fish from the shore or head out on the water in search of bass, bluegill, and perch. Canoes, kayaks, and small electric-motor boats are allowed, so paddlers have plenty of room to glide.
Canoe rentals are offered at certain times, so check ahead if you do not own a boat.
Bird lovers should bring binoculars. The park is known for a surprising variety of wildlife, from hawks and foxes to the occasional bald eagle.
Wildlife overlooks near the water make great places to pause and scan the treetops.
I think the lake is at its best early in the day, when mist sometimes hangs low over the surface. A thermos of cocoa and a folding chair can turn a simple visit into a mini retreat.
Just remember to pack out any trash.
A Playground for Pups
Tails wag faster the moment dogs spot the off-leash area, and it is easy to see why. This fenced space gives pups room to run, sniff, wrestle, and make new friends without a leash holding them back.
It sits near the Creative Arts Center, so it is simple to find.
The area is split into two sections, one for dogs over 35 pounds and another for smaller breeds. That setup keeps tiny terriers from getting bowled over by energetic retrievers.
Everyone gets to play at their own speed.
Beyond the dog run, many trails in the park welcome leashed dogs, which makes this a favorite outing for pet owners. The mix of meadows, woods, and lakeside paths gives curious noses endless new smells to explore.
Trash cans along the way make cleanup easy.
A few friendly tips can make the visit smoother. Bring fresh water and a bowl on hot days, and keep a towel in the car for muddy paws after rain.
Watch for ticks after walks in grassy or wooded spots, too. Your pup will probably nap the whole ride home.
Courts, Fields and Open Lawns
Pop, pop, pop. That steady rhythm usually means someone is rallying on the four tennis courts, which are also lined for pickleball.
Courts are first-come, first-served, so an early arrival can save you a wait.
Team sports have a home here as well. A regulation-size rugby field is available by reservation for league play, and the wide open fields invite casual games of catch or frisbee.
There is even a DIY bike repair station for quick fixes on the go.
Families will appreciate the playground, which works well for both younger and older kids. It connects to the Inner Loop, so parents can mix playtime with a stroll.
Benches nearby give grown-ups a chance to sit and recharge.
Winter does not shut things down either. When enough snow covers the ground, the meadows and trails open up for cross-country skiing and snowshoeing, turning the park into a quiet, sparkling playground.
Fall brings its own show, with bright leaves that make even a simple jog feel scenic.
Call boxes placed around the grounds add peace of mind for solo exercisers.
Picnics Under the Old Orchard Trees
Food simply tastes better outside, and this park gives you plenty of places to prove it. Picnic tables are scattered around shady corners, perfect for a sandwich break between trails.
Spreading a blanket on the big lawns works just as well.
Planning a bigger get-together? Reservable group picnic areas are ideal for birthdays, family reunions, and team outings.
The Old Orchard Picnic Shelter and a large Picnic Tent both come with grills, which means burgers and veggie skewers are on the menu.
The Old Orchard name nods to the apple orchard that once grew on the estate. That little detail adds a sweet touch of history to an otherwise ordinary lunch.
For a smooth day, reserve group spaces well in advance, especially for weekends in late spring and summer. Pack extra napkins, a tablecloth clip or two, and a trash bag to carry out leftovers.
Portable restrooms are located throughout the park, and indoor restrooms are available at the Visitor Center and Creative Arts Center.
After eating, a slow loop around the nearby paths is the perfect way to wrap up the meal.
A Theater Barn With a Past
Applause has replaced hoofbeats inside the Thompson Park Theater Barn. The rustic building started life as a yearling barn, where young horses were housed on the farm.
Now it holds a stage, lighting, a sound system, and seating for around 200 people.
Most shows happen during the warmer months. Plays, concerts, and spoken word events fill the calendar, and the barn also hosts park programs and performing arts camps for kids.
Catching a performance in a building with this much history feels pretty magical.
A little planning goes a long way here. The park opens early in the morning, with plenty of parking spread across several lots.
Bring layers, bug spray, and a refillable water bottle, since it is easy to lose track of time once you start wandering. Check the event schedule before your trip to see what is on.
From champion racehorses to pottery wheels and peaceful lake views, this old estate has found a wonderful second life as one of the best green spaces in New Jersey. You can visit Thompson Park at 805 Newman Springs Rd, Lincroft, NJ 07738, United States.
