You’re driving through Morris County, past the strip malls and the suburban sprawl of Rockaway, and suddenly the trees just... take over. That’s the edge of Farny State Park NJ. It’s huge. We're talking about 4,800-plus acres of dense, rugged Highland forest that feels like it belongs in the middle of the Adirondacks rather than forty minutes from the Lincoln Tunnel. But here is the weird thing: nobody is ever there.
If you go to nearby Pyramid Mountain to see Tripod Rock, you’ll fight for a parking spot. If you head to High Point, you’re hiking in a crowd. But Farny? It’s a ghost town. Honestly, that is its greatest strength. It is a "primitive" park, which is just New Jersey Department of Environmental Protection (NJDEP) code for "we didn't build any bathrooms or paved lots, so good luck."
It’s raw. It’s quiet. It’s a bit intimidating if you aren't used to navigating without a visitor center.
The Split Personality of Farny State Park NJ
Most people think of a state park as a cohesive block of land. Farny isn't like that. It’s a jigsaw puzzle of protected parcels squeezed between the Splitrock Reservoir and the Picatinny Arsenal. Because it shares a border with a military installation, there are parts of the woods where you’ll see some pretty serious "No Trespassing" signs. Don't ignore those. You don't want to explain to a base MP why you were chasing a bird photo across a federal line.
The park serves as a critical link in the Farny Highlands, a massive corridor of green that keeps our water clean and our bears happy. It’s managed by the New Jersey Division of Parks and Forestry, but they definitely take a hands-off approach here. You won't find many manicured paths. You will find rocks. Lots of rocks. This is the New York-New Jersey Highlands region, defined by Proterozoic crystalline bedrock that’s about a billion years old. It makes for tough hiking and incredible drainage.
The Hiking Reality Check
Don't show up here in flip-flops. Seriously. The trails in Farny State Park NJ are rocky, often muddy, and sometimes poorly marked where the blazes have faded on the oaks. The primary artery is the Splitrock Loop, which technically circles the reservoir but crosses through Farny land. It’s a rugged 11-mile commitment. Most casual hikers prefer the Four Birds Trail.
The Four Birds Trail is the crown jewel of the Highlands. It stretches about 19 miles in total, but the stretch through Farny is particularly moody. You’ll walk through stands of hemlock that have survived the woolly adelgid infestations and climb over ridges that give you a peek at the Manhattan skyline on a clear day. It’s a weird juxtaposition. You’re standing in a forest so silent you can hear your own heartbeat, looking at a distant skyscraper where millions of people are screaming into phones.

Why the Wildlife Loves the Neglect
Because humans are scarce, the animals have moved back in. It’s one of the best places in North Jersey to spot a Timber Rattlesnake. Now, don't freak out. They aren't jumping out of trees at you. They’re shy, state-endangered residents of the talus slopes. If you see one, give it a wide berth and feel lucky; most people live in NJ their whole lives and never see a wild rattler.
Black bears? Everywhere. The Farny Highlands have some of the highest bear densities in the lower 48 states. You need to be bear-aware. No headphones. Make a little noise. If you’re hiking with a dog, keep it on a leash unless you want a very expensive and tragic vet bill.
Then there are the birds. Ornithologists frequent this area because it’s a critical nesting site for Red-shouldered Hawks and Barred Owls. If you come at dusk, the "Who cooks for you?" call of the Barred Owl echoes through the valleys in a way that feels genuinely prehistoric.
The Water Connection
Water is the reason this park exists. The NJ Highlands Water Protection and Planning Act was designed to keep this specific area undeveloped because it filters the drinking water for millions of people in Newark and Jersey City. When you’re hiking through the wetlands of Farny, you’re looking at the source of someone’s morning coffee.

The park is mostly hardwood forest—oak, hickory, and maple. In the fall, it’s a riot of color, but without the leaf-peeping traffic jams you get on Route 206. Because the terrain is so undulating, the water collects in "vernal pools." These are temporary ponds that dry up in the summer but are absolutely teeming with wood frogs and spotted salamanders in March and April. It’s a loud, slimy, wonderful mess.
Navigating the Lack of Infrastructure
Let’s talk about the "primitive" aspect again. If you’re looking for a picnic table or a playground, go to Central Park. Farny State Park NJ is for the person who wants to get lost—metaphorically, hopefully.
- Parking: There isn't a main gate. Most people park in the small dirt pull-offs along Split Rock Road or near the Winnebago Scout Reservation entrance.
- Cell Service: It’s spotty. The ridges get 5G, but the valleys are dead zones. Download your maps (Avenza or AllTrails) before you leave the house.
- Facilities: Zero. None. Pack out your trash and bring plenty of water.
One of the biggest misconceptions is that you can launch a boat from within the park. You can't. While the park surrounds parts of the Splitrock Reservoir, the boat launch is managed by Jersey City and requires a specific permit. People often get confused and try to drag kayaks through the woods from Farny trails. Don't be that person. It’s a long, miserable haul for no reason.
The Historical Echoes
You’ll stumble over stone walls deep in the woods. These aren't just random piles of rocks; they’re the remnants of 18th and 19th-century farms and iron mining operations. The Farny area was once part of the massive iron industry that fueled the Revolutionary War. There are old "test pits" scattered through the forest—small holes where miners dug to see if they’d hit a vein of magnetite.
Most of these have been filled in or fenced off, but the landscape still bears the scars. The trees you see today are mostly second or third-growth. During the iron boom, almost every tree in these hills was cut down to make charcoal for the forges. It’s a testament to nature's resilience that it looks so wild today after being completely clear-cut 150 years ago.
Why It Matters Now
In 2026, we’re more connected than ever, which is exactly why places like Farny are becoming essential. It’s a sensory deprivation tank made of trees. There is something deeply grounding about the fact that this land isn't optimized for our convenience. It doesn't care if you're there. It doesn't have a gift shop. It just exists as a massive, green sponge.
Is it the "best" park in New Jersey? Depends on what you want. If you want a paved stroll, it’s terrible. If you want a place where you can hike for four hours and not see a single soul while your boots get caked in ancient mud? It’s the best place in the world.
Essential Steps for Your Visit
- Map it out: Get the NY-NJ Trail Conference Map #125. It’s the only one that is consistently accurate for this specific topography.
- Check the Calendar: During hunting season (especially buck season in December), the park is open to hunters. Wear blaze orange. Actually, just wear blaze orange anyway. It’s a good habit in the Highlands.
- Start Small: Don't try the full Splitrock Loop on your first go. Park on Split Rock Road and hike into the Four Birds Trail for two miles, then turn back. Get a feel for the elevation changes first.
- Gear Up: Wear high-ankle boots. The "trap rock" in this region is notorious for rolling ankles.
- Leave No Trace: This isn't a suggestion. Because there are no cleanup crews, any trash you leave stays there until a bear eats it or a volunteer finds it three years later.
Farny State Park NJ is a reminder of what New Jersey looked like before the highways and the housing developments. It’s rugged, slightly inconvenient, and absolutely beautiful in its indifference to us. Grab a map, tell someone where you're going, and go see the wild side of the Garden State.
