(CNN)-- Do you dare to visit the "Door to Hell" in the Turkmenistan desert? You might think it's an ordinary crater, but it's actually one of the strangest landmarks on Earth. (Watch the video above)

The story began in the 1970s, when a landslide occurred during gas exploration operations, forming a large crater that was later set on fire to prevent the leakage of toxic gases.

It was previously believed that the flames would die out within a week or ten days, but contrary to all estimates, they are still burning to this day.

The gas crater has turned into a tourist destination visited by travelers from all over the world, including Fares Al-Muslim, one of the founders of the travel company "Blue Book" in Kuwait.

He said in an interview with CNN Arabic: "I felt awe when I saw it for the first time, as it gives a completely different feeling that cannot be conveyed by photos or videos."

When to visit it?

The crater, which ranges between 60 and 70 meters in diameter and about 30 meters deep, offers completely different views between night and day.

Al-Muslim explained that the flames can be seen from great distances, and become clearer the closer the visitor gets to the site, especially in pitch darkness.

Although the flames today may not be as strong as they were in the past, that does not diminish their attractiveness or striking presence.

The site has been equipped to safely receive visitors according to the Kuwaiti traveler, with barriers placed at the edges of the crater to prevent any potential danger.

He, in turn, recommends visiting it during spring or autumn, when the weather is milder, away from the intense heat of summer and the harsh cold of winter.
