Door To Hell, Turkmenistan

The flames are going out. That is the single most important thing to understand about the Darvaza gas crater in Turkmenistan right now. Infrared surveys conducted in 2025 and 2026 show the fire intensity has dropped by more than 75 percent over three years. Turkmengaz, the state gas company, has drilled diversion wells around the site and announced a formal plan to extinguish the blaze permanently. What was once a 70-metre cauldron of roaring orange fire is today a charred bowl with scattered low flames. If you have been thinking about going, the window is narrowing.

That urgency matters because visiting Turkmenistan is not simple. The country ranks among the most restricted on Earth for independent travel, and a tourist visa requires a formal Letter of Invitation that must be arranged through a licensed operator. Most travellers find the most practical route is a fully organised tour that handles the invitation letter, in-country transport, and camping logistics as a package. Budget around $500 per person per day for a reputable multi-day itinerary, or look at six-day group departures that sometimes come in around $1,800 all-inclusive. Visas should be sorted at least six months ahead; some operators have been known to wait 12 months for approvals during busier periods.

The Crater and How to Get There

The Darvaza crater sits in the Karakum Desert near the village of Derweze, roughly 260 km north of Ashgabat. The drive takes about four hours each way, partly on a paved highway and partly on desert track that requires a four-wheel-drive vehicle. There is no public transport to the site. Tour operators typically depart Ashgabat in the afternoon so visitors arrive around sunset, camp overnight at the rim, and return the following morning.

The 1971 origin story is stranger than most guides admit. Soviet geological teams were drilling for natural gas when the ground collapsed, opening a large sinkhole above a gas pocket. The standard account says engineers lit the gas to prevent methane poisoning, expecting it to burn out within weeks. But Turkmenistan keeps no official record of the event, and some local geologists argue the collapse happened in the 1960s while the fire was not started until the 1980s. The exact date, the identity of the engineers involved, and even the precise decision to ignite the crater remain officially unconfirmed. The Soviet state bureaucracy apparently generated no retrievable paperwork for one of the twentieth century’s most spectacular accidental monuments.

The crater itself is roughly 70 metres wide and 20 metres deep. At its peak, you could hear it from several hundred metres away, a low roar beneath the desert wind. In its current diminished state the sound is far quieter, and recent visitors have described patches of flame rather than the inferno visible in older photographs. It is still a striking sight after dark, particularly when seen from the crater rim with the Karakum spread out silently in every direction, but anyone arriving with expectations set by a decade-old image may be surprised by how much has changed.

Two other smaller craters lie within a few kilometres: one filled with boiling mud, one with blue-tinged water. These receive almost no separate coverage in travel writing but are worth the short detour and provide useful context for the geology of the area. The Darvaza field sits over a vast natural gas deposit and the three craters are connected expressions of the same underground system.

Timing and Crowds

The Karakum is brutal in summer. Daytime temperatures regularly exceed 45 degrees Celsius in July and August, and the crater’s radiated heat adds to the discomfort. April through early June and September through October give the most bearable conditions. Winter visits are possible and even beautiful in years when the desert gets light snow, but nights at the campsite drop well below freezing and proper gear is non-negotiable. Turkmenistan does not observe daylight saving time and sits in TURKM (UTC+5), which is useful to know when coordinating with operators in Europe or Central Asia.

Crowd management is not really an issue in the way it is at heavily-visited sites elsewhere. Turkmenistan’s visa bottleneck keeps annual visitor numbers extremely low. The crater itself has no formal timed-entry system or ticket booth; access is controlled entirely by the logistics of how you got there, which means your tour group and maybe one or two others. If you want genuine solitude you are far more likely to find it here than at almost any comparably dramatic natural landmark on Earth.

Ashgabat: Before and After

Most itineraries spend a night or two in Ashgabat at either end of the desert trip. The capital is genuinely strange: a city rebuilt almost entirely in white marble after a devastating 1948 earthquake and then transformed into a monument to presidential ego during the Turkmenbashi era. The Guinness Book of Records has recognised it for having the world’s highest density of white marble buildings. The National Museum of Turkmenistan covers the country’s archaeology and nomadic history with more depth than most visitors expect. For food, Nury restaurant near the city centre serves reliable plov, shashlyk, and lagman; the mutton dishes in particular are worth ordering.

If you have budget flexibility, the Oguzkent Hotel is the highest-spec option in Ashgabat and is sometimes included in tour packages. More modest operators use smaller guesthouses that are perfectly adequate for the purpose of a one-night transit stop before a desert drive.

What to Pack

The desert requires preparation that goes beyond the obvious. Water consumption at the crater site is higher than expected because of the radiated heat even at night. Bring significantly more than you think you need. A head torch with fresh batteries matters; the crater after dark is dramatic precisely because there is no other light source for many kilometres, and navigating the rim in the dark without a torch is genuinely hazardous. Dust gets into everything, so phones and cameras benefit from a sealed bag. The crater’s edge has no fence or safety barrier of any kind.

For the return to Ashgabat, the most common crowd-dodge is to leave the crater very early in the morning rather than the standard post-breakfast departure. Dawn light on the Karakum is its own reward, and you will almost certainly have the site entirely to yourself.

The Darvaza crater has probably a year or two of meaningful fire remaining, possibly less. Whatever the government’s final timeline proves to be, the direction is clear and it is one-way. A visit now, even to a reduced version of what the crater once was, is still an encounter with something that exists almost nowhere else: a mistake from half a century ago that burned long enough to become a wonder.
