In the middle of Turkmenistan’s Karakum Desert, a pit roughly the width of a football field has been on fire for more than half a century. Known to travelers as the Door to Hell, the flaming crater near the village of Derweze has glowed without pause since 1971, and it has become one of the strangest human-made landmarks anywhere on Earth.
The fire is not a volcano or a natural vent. It is a burning field of natural gas that a drilling accident is widely believed to have opened, and which was then deliberately set alight in the expectation that the flames would die out within days. Instead they have kept burning for more than fifty years, feeding on gas that seeps up from beneath the desert floor.
How a Soviet drilling rig is said to have opened the Darvaza crater
The most repeated account traces the crater to 1971, when Soviet geologists were prospecting for natural gas in the Karakum. According to that story, a drilling rig punched into a large underground pocket of gas, and the ground beneath the equipment collapsed, swallowing the rig and leaving a wide crater venting methane into the air. Worried that the escaping gas was poisonous and could spread, the engineers reportedly decided to burn it off, assuming the reserve would exhaust itself in a matter of weeks. The reserve turned out to be far larger than expected, and the flames never stopped.
Why the methane keeps the flames alive
The crater sits above a natural gas field, and gas continues to migrate upward through fractures in the rock and into the pit. As long as that supply keeps arriving and oxygen reaches the surface, combustion continues. Natural gas is mostly methane, an energy-rich fuel that burns readily, so a steady seep produces a steady fire. The pit essentially acts as a self-sustaining burner: fuel rises from below, mixes with desert air, and ignites against the flames already present. That balance is why the blaze has outlasted the Soviet Union itself. A comparable seep in a wetter climate might be doused by rain or smothered by shifting soil, but the arid, sparsely populated desert offers nothing to interrupt the cycle. The flames simply persist, year after year, in a place where almost no one is around to disturb them.
What the pit looks like up close
The crater is a roughly circular depression about 70 meters across and some 20 to 30 meters deep, its walls lined with dozens of smaller vents that flicker with orange flame. By day it can look like little more than a scorched hole in the sand, but after dark it becomes a glowing basin visible from a distance, throwing heat and light across the surrounding dunes. The effect, especially at night, is what earned the site its nickname among visitors and helped turn a remote industrial mishap into a destination. A survey of unnerving destinations describes it plainly as a gas crater that has been burning continuously for decades.
A disputed origin story
The dramatic 1971 collapse is the popular version, but it is not universally accepted. Some Turkmen geologists have questioned the details, suggesting the crater may have formed in the 1960s and only been set alight later, and pointing out that firm contemporary documentation of the event is thin. What is not in dispute is the physical reality: a large gas-fed fire that has burned for generations. The gap between a vivid, widely told tale and the sparse record behind it is a reminder that even famous landmarks can carry origin stories that are difficult to verify decades after the fact.
Turkmenistan’s gas wealth and repeated vows to close the pit
Turkmenistan holds some of the largest natural gas reserves in the world, and that wealth is central to the country’s economy and exports. Against that backdrop, an open pit venting and burning gas represents both a curiosity and a waste of a valuable resource, as well as a source of carbon emissions. Turkmen leaders have periodically announced intentions to extinguish the fire or otherwise deal with the crater, framing it as an environmental and economic concern and even proposing to capture the gas instead of letting it burn. Yet the flames have proven stubborn, and each vow to put out the Door to Hell has so far left it burning.
A remote landmark that became a tourist draw
For a country that has long been difficult for outsiders to visit, the crater has become an unlikely magnet. Travelers make the trip across the desert to camp near the rim and watch the fire at night, and the site features prominently in Turkmenistan’s small but growing tourism image. It has drawn adventurers, photographers, and at least one high-profile stunt in which an explorer descended into the pit in a heat-resistant suit to study the extreme environment at the bottom. That mix of danger, spectacle, and mystery is precisely what keeps the Door to Hell in the public imagination: a fire lit for a few days’ convenience that has instead become a permanent feature of the landscape, still burning long after the people who struck the match are gone.
