Door to Hell Turkmenistan

The Clock Is Ticking on One of Earth’s Most Surreal Spectacles

In autumn 1971, a team of Soviet geologists drilled into what looked like solid desert floor near the village of Darvaza, punctured the roof of an underground methane cavern, and watched their drilling rig disappear into the earth. Their fix was pragmatic to the point of absurdity: they lit the escaping gas on fire and assumed it would burn out within weeks. More than five decades later, the crater they created still throws orange light across the Karakum Desert every night. Except now, for the first time, the flames are genuinely fading.

Infrared satellite data published in 2025 and early 2026 shows that heat intensity from the Darvaza crater has dropped by more than 75 percent over the past three years. Turkmen scientists have drilled several new wells around the perimeter to siphon off methane before it reaches the main pit, and the government has announced a formal plan to extinguish the crater entirely. If you have ever intended to see it, go now. The window is closing in a way that Soviet engineers never managed to arrange.

What You Are Actually Looking At

The crater is roughly 70 metres wide and 20 metres deep. The popular name “Door to Hell” is a Western invention; Turkmen locals more often call it the Gates of Hell, and the official name is simply the Darvaza gas crater. The surrounding area, also called Darvaza, sits in the Ahal Province about 260 kilometres north of Ashgabat, deep inside the Karakum Desert, one of the world’s largest sand deserts and a landscape so flat and featureless that the glow of the crater is visible from several kilometres away on a dark night.

The historical record of the crater’s exact origin is murkier than the popular story suggests. Some Turkmen geologists have argued the ground collapse happened in the 1960s and that the fire was only lit in the 1980s, specifically to prevent toxic gas from reaching a nearby village. Relevant Soviet-era documents remain classified or lost. The 1971 date is the most widely accepted but it is worth knowing it rests on incomplete evidence, not a clean archive.

One environmental complication worth understanding before you visit: the crater currently emits roughly 1,300 to 1,960 kilograms of methane per hour. When methane burns, it converts to carbon dioxide, which is a far less potent greenhouse gas in the short term. If the fire goes out completely, that raw methane goes straight into the atmosphere. Scientists are divided on whether fully extinguishing the crater is, on balance, environmentally better or worse than letting it burn.

Getting There

Reaching Darvaza from Ashgabat takes around four hours by road, almost entirely across open desert. The most reliable approach is booking with an established operator who holds a valid licence to bring foreign tourists into the country, because Turkmenistan’s visa process is one of the most restrictive in the world.

Most nationalities cannot obtain a Turkmenistan tourist visa independently. You need an invitation letter issued by a licensed local tour operator or a Turkmen sponsor. The visa fee runs around $85 to $89 USD, with an additional migration tax of $10 to $14 USD. Denial rates are high, and the earliest you can apply is three months before your intended entry date. Budget significant lead time and do not book non-refundable connecting flights until the visa is confirmed.

A newer option that some visitors have found practical is the overnight train from Ashgabat. It arrives at Darvaza station around 23:00, allows roughly four hours at the crater, and returns to the capital by around 03:00. This is not a comfortable itinerary but it is substantially cheaper than a full multi-day desert tour and it puts you at the crater at the right time, since the flames are most dramatic in complete darkness.

Organized tours range considerably in price. Small-group packages from operators based in Uzbekistan or Kyrgyzstan (which enter Turkmenistan on a transit arrangement) can be found for under $400 USD per person including accommodation and meals. Tours arranged from within Turkmenistan through companies like Koryo Tours start at $2,300 USD per person for a longer itinerary. The crater itself has no entrance fee; what you pay covers transport, guides, and the obligatory visa handling.

When to Go

April through early June and September through October are the most comfortable months. Karakum summer temperatures regularly exceed 45 degrees Celsius in July and August, making a stay near the open pit genuinely dangerous. Winter nights drop below freezing, which is cold but manageable, and the absence of summer haze can make the surrounding dunes look sharper and more dramatic.

One timing detail that catches people out: Turkmenistan observes UTC+5 year-round with no daylight saving time, while Ashgabat-based tour departure times are given in local time. If you are connecting from a country that changes clocks seasonally, double-check the arithmetic, particularly if you have booked the overnight train option.

At the Crater

There are no fences around the crater. Visitors stand at the rim, which gives off heat significant enough to feel on your face and forearms from ten metres away. At night, the glow renders the surrounding sand in deep amber and the sky above turns a warm orange that cameras struggle to capture accurately. The smell of sulphur is present but not overwhelming at rim distance; it intensifies if the wind shifts.

A small number of operators organize camping experiences overnight, setting up tents 300 to 500 metres from the rim. This is the single best way to experience the crater, partly because the spectacle genuinely peaks in the hours between midnight and 3 AM when day-trip visitors have left, and partly because the desert silence around the fire is unexpectedly affecting. One traveller who went in 2024 described it as standing next to a sleeping volcano that has not yet decided whether to erupt.

Two smaller craters are located nearby: one contains a mud volcano that bubbles slowly and silently, and another has a pool of burning natural gas at its base. Most tours include a stop at both. The mud volcano, in particular, is underrated. It is much quieter than Darvaza and the surface around it shifts colour depending on the angle of light, from grey-white at noon to near-purple at dusk.

Accommodation Options

There are no hotels at Darvaza. Overnight visitors stay in yurts or basic tented camps arranged by tour operators, with communal meals typically consisting of pilaf (rice cooked with lamb and carrots), shashlik (grilled meat skewers), and flatbread. The quality varies by operator; it is worth reading recent reviews specifically about the camp setup rather than the overall tour rating, since the logistics diverge significantly between companies.

For anyone spending a night in Ashgabat before or after the crater trip, the Oguzkent Hotel is the largest and most centrally located option in the capital. It is not cheap by Central Asian standards but it is reliable for bookings and has English-speaking front desk staff, which matters given that Ashgabat is not a straightforward city for independent navigation.

Beyond the Crater: What Else Turkmenistan Offers

Ashgabat is worth a day or two on its own merits. The city is covered in white marble to a degree that must be seen to be believed: the Guinness World Records listed it as the world’s highest concentration of white marble-clad buildings. The city’s monuments and public squares are designed to project the personality cult of the Berdimuhamedow family in a way that is both disconcerting and genuinely fascinating as a piece of political architecture.

Ancient Merv, about 350 kilometres east of Ashgabat near the city of Mary, is a UNESCO World Heritage Site and one of the great Silk Road oases. At its height in the 12th century, Merv was among the largest cities in the world, with a population estimated at between 200,000 and 500,000. The site is almost entirely unexcavated; you walk among earthen ruins with almost no other tourists, which is rare for a UNESCO site of this scale.

The Yangykala Canyon in the northwest, near the Caspian coast, is one of the most photogenic landscapes in Central Asia and appears in almost no major travel publications. Sheer walls of red and white sandstone drop 60 to 100 metres to a flat canyon floor, and the canyon is long enough that the light changes dramatically as you walk through it. Getting there requires a 4WD vehicle and around six hours from Ashgabat.

A Practical Note Before You Go

The Darvaza crater may not look the same in two years. The government’s plan to redirect gas away from the pit is progressing, and satellite readings confirm the fire is weakening. Whether it extinguishes fully, stabilises at a reduced burn, or somehow reignites is genuinely unknown. The most reliable strategy, if you want to see it at its most dramatic, is to stop thinking of it as a permanent fixture and start booking now.
