Door to Hell
In 1971, Soviet engineers set a gas crater on fire expecting it to burn out in days. It's been burning for over 50 years. A 230-foot wide pit of endless flame in the desert. They literally created a gate to hell. It still burns.
In the heart of the Karakum Desert, in a remote corner of Turkmenistan that few outsiders have ever visited, a pit of fire has been burning continuously for over fifty years. The Darvaza gas crater, known locally and internationally as the Door to Hell, stretches 230 feet across and plunges 65 feet into the earth, its floor a roiling mass of flames that have never been extinguished since Soviet engineers lit them in 1971. What was supposed to be a controlled burn lasting days at most has become a permanent feature of the landscape, a literal gateway to what looks like the underworld, visible for miles across the flat desert terrain. The fire burns day and night, year after year, decade after decade, consuming natural gas that continues to seep from the earth in quantities that no one anticipated. The Door to Hell is an accident that became a monument, a catastrophic engineering failure that has transformed into one of the world’s most surreal tourist destinations.
The Origin
The story of the Door to Hell begins with Soviet exploration of Turkmenistan’s vast natural gas reserves in 1971. Soviet geologists identified a site near the village of Darvaza as promising for natural gas extraction and began drilling operations. The Karakum Desert sits atop one of the world’s largest natural gas fields, and the Soviets were eager to tap this resource for the energy needs of the USSR.
What the geologists found exceeded their expectations, though not in the way they had hoped. During the drilling operation, the ground beneath the equipment collapsed, opening a massive sinkhole that swallowed the drilling rig and associated equipment. The collapse revealed a natural gas pocket of enormous size, and gas immediately began venting into the atmosphere from the newly opened crater.
The situation presented the Soviet engineers with a dilemma. Methane, the primary component of natural gas, is a potent greenhouse gas and also poses health risks to nearby populations when released in large quantities. The village of Darvaza was close enough to be affected, and the engineers needed to address the uncontrolled gas release quickly.
The Decision
Faced with a massive crater continuously venting natural gas, the Soviet engineers made what seemed like a reasonable decision at the time: they would set the gas on fire. Burning the methane would convert it to carbon dioxide and water vapor, both less immediately harmful than unburned methane. More importantly, the engineers expected that the gas pocket would burn out within a few days, at most a few weeks. Once the available gas was consumed, the fire would die, and the crisis would be resolved.
In 1971, the engineers ignited the gas escaping from the crater. The flames caught immediately, transforming the pit into a roaring inferno. The engineers waited for the fire to burn itself out.
They are still waiting.
The gas pocket that collapsed beneath the drilling rig was far larger than anyone had estimated. The reservoir of natural gas feeding the flames has proven essentially inexhaustible on human timescales, continuously venting fuel that keeps the fire alive. Days turned to weeks, weeks to months, months to years, years to decades. The fire that was supposed to last a few days has now been burning for over half a century.
The Crater Today
The Door to Hell in its current state is a spectacular and terrifying sight. The crater measures approximately 230 feet in diameter and drops roughly 65 feet to the burning floor below. The walls of the pit are irregular, formed by the initial collapse and modified by decades of heat exposure. The floor is not uniformly aflame but rather dotted with hundreds of individual fire points where gas vents to the surface, creating a landscape that genuinely resembles traditional depictions of hell.
At night, the effect is particularly dramatic. The flames illuminate the crater and cast a glow visible for miles across the flat desert. The heat rising from the pit creates shimmering distortions in the air, and the sound of the burning gas provides a continuous roar that can be heard from considerable distance. Standing at the edge of the crater, looking down into the flames, visitors report the sense that they are looking into another world, one governed by fire rather than water and air.
The temperature at the crater’s edge is noticeably elevated, and the closer one approaches, the more intense the heat becomes. The rim of the crater is unstable in places, with ongoing erosion causing occasional collapses that expand the pit’s diameter. Visitors are warned to maintain safe distances, though the exact definition of “safe” varies depending on who is providing guidance.
Environmental Impact
The Door to Hell represents an ongoing environmental catastrophe, though one that has become so normalized by its duration that it rarely generates the attention such disasters typically receive. The crater releases massive quantities of carbon dioxide into the atmosphere every year, contributing to climate change on a scale comparable to a significant industrial facility. The natural gas being burned could have been captured and used for energy; instead, it contributes nothing but atmospheric carbon.
The exact quantity of gas released is difficult to measure, but estimates suggest that the crater burns through millions of cubic meters of natural gas annually. Over fifty years, the total waste represents an enormous squandering of a valuable natural resource, one that Turkmenistan could otherwise have exported for considerable revenue.
Efforts to extinguish the fire or cap the gas release have been proposed repeatedly but never successfully implemented. The technical challenges are significant: the crater is large, the gas flow is continuous, and any intervention would need to be conducted in extremely hostile conditions. The Turkmenistan government has announced plans to close the crater on multiple occasions, most recently in 2022 when President Gurbanguly Berdimuhamedow ordered that the fire be extinguished and the area developed for tourism infrastructure. As of now, the fire continues to burn.
Tourism
The Door to Hell has become one of Turkmenistan’s most popular tourist attractions, drawing visitors from around the world who want to see the famous burning crater for themselves. The journey is not easy; Darvaza is remote, located hours from any significant city, accessible only by rough desert roads that require four-wheel-drive vehicles. Most visitors come on organized tours that provide transportation, camping equipment, and guides familiar with the area.
Camping near the crater has become a popular activity, particularly at night when the flames are most impressive. The desert around the pit is flat and empty, providing unobstructed views of the fire from all directions. The combination of remote location, extreme landscape, and surreal visual spectacle creates an experience that visitors describe as otherworldly.
The Turkmenistan government has attempted to develop tourism infrastructure around the crater, with varying degrees of success. The remoteness of the location makes permanent facilities difficult to maintain, and the harsh desert environment limits the tourism season to cooler months. Nevertheless, the Door to Hell continues to attract thousands of visitors annually, all seeking to witness the result of an engineering decision that went spectacularly, permanently wrong.
An Unintended Monument
The Door to Hell stands as an unintended monument to human hubris, a reminder that our attempts to control nature do not always proceed as planned. The Soviet engineers who lit the fire in 1971 expected to solve a problem; instead, they created a phenomenon that has outlasted the Soviet Union itself. The fire burns on, indifferent to human desires, fed by geological processes that operate on timescales we can barely comprehend.
Whether the Door to Hell will ever be closed remains uncertain. Technical solutions exist in theory, but implementing them would be expensive, dangerous, and potentially futile if the gas pocket is as large as it appears to be. The fire might continue to burn for decades more, perhaps for centuries, a permanent feature of the Turkmenistan landscape that future generations will inherit from the engineers who thought it would burn out in days.
In 1971, Soviet engineers set fire to a gas crater in the Turkmenistan desert, expecting the flames to die within days. Over fifty years later, the Door to Hell still burns, a 230-foot wide pit of eternal flame that has become one of the world’s strangest tourist destinations. The fire consumes millions of cubic meters of natural gas annually, an ongoing environmental disaster that has become normalized by its duration. Plans to extinguish it have been announced and abandoned. The fire continues, a monument to an engineering decision that created something its makers never intended and cannot undo.
