Darvaza gas crater tour to explore “Door to Hell”, 60 meters diameter hole that has been burning since 1971. Its name translated as 'gates', Darvaza is a small Turkmen settlement located close to the border with the Dashoguz region, and the start of a special permit zone. Darvaza has 350 inhabitants, most of them Turkmens of the Teke tribe, and at the settlement many people continue their half-nomadic lifestyle by setting up yurts in front of their simple houses. While Turkmenistan is not a major tourist destination, Ashgabat does attract some visitors interested in its unique architecture and culture. The Darvaza gas crater, also known as the "Gate to Hell" or the "Door to Hell," is a natural gas field that collapsed into an underground cavern in Darvaza, Turkmenistan, in 1971. Geologists intentionally set it on fire to prevent methane gas from spreading, and it has been burning continuously ever since.The Darvaza gas crater is a unique and somewhat controversial site. It is a striking example of a human-caused environmental event, but it has also become a symbol of the country and a draw for tourism.
