You’ve seen the movies where a hidden door in a basement leads to a fiery pit. It's a classic trope. But humans have a strange, recurring obsession with finding actual, physical entrances to the underworld. We aren't just talking about metaphors here. Across the globe, there are places so hostile, so deep, or so biologically bizarre that ancient and modern cultures alike labeled them "gates to hell."
Most of these spots don't involve demons with pitchforks. They involve tectonic shifts, toxic gases, and historical accidents. If you're looking for a literal entrance to the afterlife, you're going to be disappointed. However, if you want to see where the Earth looks like it’s actually trying to kill you, these locations are as real as it gets. People often mistake these for mere tourist traps, but the science behind why they exist is usually scarier than the myths.

The Darvaza Gas Crater is a human-made disaster
If you want the most visually literal "path to hell," you go to Turkmenistan. In the middle of the Karakum Desert, a hole has been burning for over fifty years. It’s 230 feet wide and looks like a localized apocalypse.
It wasn't a curse that opened this pit. It was Soviet engineers in 1971. They were drilling for oil and tapped into a massive natural gas cavern. The ground collapsed, swallowing their rig and creating a crater. Fearing the release of poisonous methane, the scientists did something that seemed logical at the time. They lit it on fire. They figured it would burn out in a few weeks. It’s still burning today. Experts at The Points Guy have provided expertise on this trend.
Walking up to the edge is an experience in pure heat and noise. The roar of the flames sounds like a jet engine. It’s a stark reminder of how badly we can mess up the planet when we stop being careful. The government has talked about closing it many times to save the natural gas resource, but it’s become the country’s biggest (and only) real tourist draw.
Mount Hekla and the medieval fear of ice and fire
Iceland is basically one giant geological warning sign. For centuries, European monks claimed Mount Hekla was the actual chimney of hell. They weren't just being dramatic. When Hekla erupts, it’s violent. It spits out "tephra"—volcanic rock—that can cover the entire island.
In 1106, a massive eruption occurred, and the stories started spreading. People claimed they saw birds flying into the fire, which they assumed were souls being dragged down. What’s actually happening is a complex interaction between the North American and Eurasian tectonic plates. The magma chambers under Hekla are incredibly active.
The mountain has erupted over 20 times since the settlement of Iceland. It’s unpredictable. Geologists watch it constantly because it doesn't give much warning. Usually, you get about 30 to 80 minutes of seismic activity before the ground opens up. That’s not enough time for a casual hike. If you visit, you’re standing on a ticking time bomb that shaped the religious fears of an entire continent.
The Plutonium at Hierapolis is a toxic death trap
In modern-day Turkey, the ancient city of Hierapolis holds a site called the Ploutonion. The Romans and Greeks believed it was a portal to the god Pluto. Priests would lead bulls into the cave, and the animals would drop dead instantly while the priests remained unharmed.
For a long time, people thought this was a magic trick or a miracle. It wasn't. In 2018, researchers discovered the cave sits directly over a deep fissure that leaks massive amounts of carbon dioxide. Because $CO_2$ is heavier than air, it forms a "lake" of toxic gas on the floor.
The bulls, having heads closer to the ground, breathed in the 90% concentration of gas and suffocated. The priests, being taller, kept their heads above the "death zone." It’s a perfect example of how ancient "magic" is often just chemistry we didn't understand yet. Don't try to test this yourself. Even today, the gas levels fluctuate based on the time of day, making the cave entrance genuinely lethal to small animals and curious humans.
Centralia is the town that’s literally burning underneath
You don't have to go to an exotic desert or an ancient ruin to find a path to hell. There’s one in Pennsylvania. Centralia was a quiet mining town until 1962, when a trash fire in a landfill ignited a coal seam deep underground.
The fire spread through the network of abandoned mines. It’s still burning. The ground in Centralia is hot to the touch. Steam rises from cracks in the asphalt of abandoned roads. The air is thick with carbon monoxide. Most of the town was demolished and the zip code was revoked.
The fire is expected to burn for another 250 years. It’s a slow-motion disaster that turned a neighborhood into a ghost town. It’s eerie because it looks normal from a distance, but when you see the "Warning" signs about ground collapse and lethal gases, you realize the hellscape is right under your boots.
The Masaya Volcano and the Cross of the Devil
In Nicaragua, the Masaya Volcano was so terrifying to 16th-century Spanish conquistadors that they named it "La Boca del Infierno" (The Mouth of Hell). They were so convinced it was a portal to the underworld that they planted a massive wooden cross on the crater's edge to exorcise the demons.
Masaya is one of the few places on Earth with a persistent lava lake. You can drive right up to the rim and look down into a swirling pool of molten rock. The sheer intensity of the sulfur dioxide clouds makes it hard to breathe. The indigenous people used to offer sacrifices to the volcano to prevent eruptions.
The Spanish didn't just fear the fire. they feared the "cinder" that fell from the sky, which they viewed as a physical manifestation of sin. Today, you can take a night tour to see the glowing lava. It’s beautiful, but the smell of rotten eggs and the heat remind you why the ancients were so eager to stay on the volcano's good side.
Why we keep looking for these places
Humans love a good scare, but we also love patterns. Every culture has a version of a subterranean world. Whether it’s the Mayan Xibalba or the Greek Hades, we instinctively look at deep holes and think "something must be down there."
Scientifically, these places are outliers. They represent moments where the Earth's internal energy breaks through the thin crust we live on. We call them paths to hell because they represent the end of our habitable environment. They are places where biology fails and geology takes over.
If you're planning to visit any of these, don't be an idiot. Follow the local safety warnings. These sites earned their reputations for a reason. They are chemically and physically dangerous.
Check the seismic activity reports for Iceland before you book a trip to Hekla. If you’re heading to Turkmenistan, hire a guide who knows the desert; getting lost in the Karakum is a much more likely way to meet your end than falling into the crater. For Centralia, stay on the main paths and don't go poking into sinkholes. The real "hell" in these places isn't supernatural—it's the very real risk of falling into a fire or suffocating on gas while you're trying to take a selfie. Treat the geology with respect and you'll get the best photos of your life without becoming part of the legend.
