You’ve probably heard the stories. If you grew up anywhere near Passaic County, the legend of the Gates of Hell in NJ is basically a rite of passage. It’s that one spot where the air feels a little too heavy and the graffiti seems to stare back at you. People talk about satanic rituals, bone-chilling screams, and a literal portal to the underworld. But if you strip away the "Weird NJ" folklore and the teenage bravado, what’s actually down there?
It’s dark. It’s wet. It’s a storm drain.
That sounds disappointing, right? Calling a legendary supernatural portal a "drainage system" feels like telling a kid Santa isn't real. But honestly, the reality of the Clifton tunnels is almost more unsettling than the ghost stories. You aren't dealing with demons; you’re dealing with decaying infrastructure, unpredictable floodwaters, and the crushing weight of urban legend.
The Physical Reality of the Clifton Tunnels
The site is officially a collection of storm water runoff tunnels located near the intersection of Clifton Avenue and Paulison Avenue. It’s tucked behind a nondescript patch of woods. For decades, it’s been the epicenter of North Jersey’s "urban explorer" scene.
The main entrance is a series of large stone arches. They look old. They look intentional. This is where the Gates of Hell in NJ name comes from. When the water is low, you can see the layers of spray paint—decades of names, dates, and pentagrams layered over each other like a crusty, neon skin.
Inside, the tunnels vary in height. In some spots, you can stand upright; in others, you’re hunched over, feeling the damp concrete vibrate whenever a car passes on the road above. The main tunnel eventually leads to a chamber that locals call "The Red Room." It’s a circular stone room where the walls are often stained with red minerals—or paint, depending on who you ask.
Why people think it's haunted
There is a very specific acoustic phenomenon in these tunnels. Because of the way the stone is curved and the various pipes feed into the main artery, sounds from the street above get distorted. A car horn becomes a moan. A distant conversation sounds like whispering right behind your ear.

Then there’s the "Black Hole." This is a smaller, square tunnel that branches off from the main path. It’s pitch black, even with a high-powered flashlight, because the soot and grime on the walls seem to swallow light. If you’re looking for a place to feel a sense of impending doom, this is it.
The Danger Isn't Spiritual
We need to be real for a second. The biggest threat at the Gates of Hell in NJ isn't a demon named Mike. It’s the rain.
Flash floods are a genuine risk in any underground drainage system. In Clifton, the tunnels are designed to move massive amounts of water from the streets to the nearby brooks. If it starts raining five miles away, that water can hit the tunnels in minutes. People have been trapped. People have drowned.
Beside the water, you have to worry about:
- Air Quality: In deep, stagnant sections, oxygen levels can drop or pockets of methane can build up.
- Structural Integrity: This isn't a maintained park. The concrete is crumbling, and rebar sticks out of the walls like rusted needles.
- The Law: The Clifton Police Department is well aware of the site's popularity. They patrol it. They ticket people. It’s trespassing, plain and simple.
Debunking the Satanic Panic
The 1980s were a weird time for New Jersey. The "Satanic Panic" was in full swing, and any place where kids hung out to smoke and listen to Black Sabbath was immediately labeled a cult headquarters. The Gates of Hell in NJ became a victim of this hysteria.
Sure, you’ll find pentagrams painted on the walls. You might even find the remains of a campfire or some animal bones. But experts like Mark Sceurman and Mark Moran, the guys behind Weird NJ, have spent years documenting these sites. Their research suggests that while "rituals" happen, they’re almost exclusively bored teenagers trying to scare each other.

There are no documented cases of cult activity or human sacrifice linked to the Clifton tunnels. There are, however, plenty of stories about people getting spooked by a stray cat or a loud pipe and running out so fast they lose their shoes.
The Mystery of the "Gatekeeper"
One of the more persistent legends involves a figure known as the Gatekeeper. Supposedly, an old man lives in the deeper recesses of the tunnels and guards the entrance to the actual underworld. He’s said to have glowing eyes or the ability to vanish into thin air.
In reality? These tunnels are frequently used as shelter by the local unhoused population. Encountering someone who is living in a dark tunnel when you’re already on edge is a recipe for a "ghost story." It’s a reminder that these places have a human element that is often sadder and more complex than the supernatural tales we invent.
Exploring the Surrounding Area
If you're interested in the vibe of the Gates of Hell in NJ but don't want to risk a trespassing charge or a face-full of runoff water, the surrounding area of Clifton and Nutley is full of similar lore.
New Jersey has a high density of these "liminal spaces"—places that feel like they’re between two worlds. Think about the old psychiatric hospitals or the abandoned factories that dot the Passaic River. The Clifton tunnels are just one piece of a much larger puzzle of New Jersey gothic.
Legal Alternatives for Urban Exploration
- State Parks: Places like Waterloo Village offer a look at abandoned structures without the legal risk.
- Organized Tours: Some historical societies in NJ offer tours of underground vaults and tunnels that are actually safe.
- Photography: Capturing the exterior of these sites from public property is often enough to satisfy the itch for the macabre.
What to Do If You Actually Go
Look, telling people not to go usually just makes them want to go more. If you find yourself standing in front of the Gates of Hell in NJ, keep your wits about you.

Check the weather. If there is a 10% chance of rain, stay out. Don't go alone. Bring three different light sources. Wear boots that can handle six inches of muck. And most importantly, remember that you are in a drainage pipe.
Respect the neighbors. People live right near the entrance. They don't want to hear screaming teenagers at 2:00 AM. They don't want their property littered with Gatorade bottles.
Summary of Safety Tips
- Monitor the sky. Rain is your worst enemy in a storm drain.
- Wear PPE. Heavy boots and gloves are non-negotiable because of broken glass.
- Tell someone where you are. If you get stuck, someone needs to know where to send the rescue squad.
- Don't touch the water. It's runoff. It's gross. It's full of street grime and bacteria.
The Gates of Hell in NJ will likely remain a staple of local legend for another fifty years. As long as there are tunnels and bored kids, the stories will persist. But the next time you hear a story about a portal to another dimension in Clifton, just remember: it's probably just the wind whistling through a 48-inch concrete pipe.
How to Handle an Encounter with the "Supernatural"
If you think you've seen something weird at the tunnels, take a breath. The human brain is hardwired for pareidolia—the tendency to see patterns (like faces) in random shapes. In a dark, graffiti-covered tunnel, your brain is going to work overtime to turn a smudge of black paint into a demon.
- Trust your gear, not your eyes. Shine your light directly at the "spirit." Usually, it turns into a pile of trash or a junction box.
- Check your CO levels. If you feel dizzy or see "shadow people," leave immediately. It’s a sign of poor air quality, not ghosts.
- Leave no trace. If you want the legend to stay "pure," don't add to the trash.
Exploring the darker corners of New Jersey is a unique hobby, but it requires a level of pragmatism that most horror movies ignore. Stay safe, stay legal, and keep the ghost stories for the campfire.
