Reflections in the Glass: The "Ghost Tunnel" of Hwangnyeongsan, Busan
It was the final day of my business trip to Busan. There was no rain, but the air was thick and heavy—the kind of humidity that makes your shirt cling to your back the second you step outside.
I had planned to grab a quick meal before catching my evening train, but a conversation with the hotel front desk clerk changed my itinerary. We started talking about the night view from Hwangnyeongsan Mountain, which naturally led to the mention of a specific tunnel. Online, it’s rarely called by its official name anymore. Most people simply know it as the “Ghost Tunnel.”
Long before the internet made it a viral hotspot, stories about this road circulated among Busan’s taxi drivers. It’s a place that locals have avoided after dark for decades. The legends are remarkably consistent, focusing almost entirely on what is seen—or not seen—in the mirrors.
The Woman in the Rearview: Stories of a woman in white who isn't visible in the tunnel's headlights but appears clearly in the rearview mirror, standing against the wall.
The Vanishing Pedestrian: Drivers swear they passed someone walking along the narrow shoulder, but when they check their mirrors a second later, the road behind them is completely empty.
The Phantom Motorcycle: The deafening roar of a bike chasing you from behind, getting closer and closer, yet nothing ever overtakes you.
A Space Built of Unreliable Shadows
I arrived at the tunnel just before sunset. A few cars were pulled over near the entrance, but the atmosphere was far from a typical tourist spot. People were filming through cracked windows or taking quick photos, but no one seemed comfortable staying for long.
I walked toward the mouth of the tunnel with my jacket tucked under my arm. The ceiling was lower than it appeared in photos, and the lighting was patchy—aged yellow lamps that left deep pockets of "dead air" where the light couldn't reach.
Visual Pressure: The road is narrow, with almost no shoulder for pedestrians. As cars passed, the flickering lights caused the shadows on the soot-stained walls to lurch and sway, mimicking the movement of someone lunging toward the road.
The Mirror Trap: Because the lighting is so inconsistent, the brain struggles to process the reflections in the mirrors. In that split-second glance, it is incredibly easy for a shadow or a stain on the wall to take the shape of a human figure.
Even knowing it was an optical trick, I couldn't stop the primal urge to keep looking over my shoulder every time I heard a car approaching from the dark.
The Sound That Refuses to Leave
Of all the legends, the "Phantom Motorcycle" felt the most plausible once I was inside. A lone delivery bike sped through while I was near the entrance, and the roar of its engine didn't just pass by—it bounced off the low ceiling and cramped walls, amplifying into a distorted scream.
Long after the bike had exited, the echo lingered in the tunnel, making it impossible to tell exactly where the sound was coming from. In the dead of night, for a driver already on edge, that persistent, disembodied roar would be enough to trigger a panic. I took a few steps into the darkness, but as soon as I saw the flash of an oncoming car's lights, I found myself backing out, eyes fixed on the void behind me.
"Did You Actually Go Inside?"
The vibe of the people there was the strangest part. No one was screaming or acting terrified. They were laughing, taking selfies, and filming TikToks. But their movements were rushed. Nobody stood still. They’d snap a photo and immediately climb back into their cars, slamming the doors just a little too hard.
Later, at a nearby convenience store, I overheard two students talking. “Did you actually go all the way inside?” one asked. The other didn't even hesitate: “No way.” That instant, reflexive "no" told me everything I needed to know about the local reputation of that road.
The "Real" Fear of the Professionals
I caught a taxi back toward the station and brought up the tunnel. The driver recognized it instantly, but he didn't lead with ghosts. He led with the road.
"People still go there for photos, but that road is a mess," he said, eyes fixed on the winding path ahead. "Tight curves, bad sightlines, and the pavement is always slick. On rainy nights, even the veterans grip the wheel until their knuckles turn white."
He kept talking about road safety, but I found myself staring at his rearview mirror. Even as we moved further away, the orange glow of the tunnel lights lingered in the glass like a pair of watching eyes.
Field Note:
The wheel on my suitcase, which had been fine all week, started rattling near the tunnel. I thought a small stone had gotten stuck in the mechanism—and when I got back to my room, I found I was right. At 2:00 AM, I picked the sharp pebble out of the wheel and finished my lukewarm coffee. I started to play back the recordings from the tunnel, but I found myself closing the laptop before the audio even started.
