Derweze, Turkmenistán
Welcome to the gates of hell. Seriously though, Derweze, Turkmenistan is the gateway to hell. It’s home to an underground crater with an incredibly high percentage of natural gas. That gas has burned nonstop since 1971 when an engineering accident occurred. That’s over three decades, and it looks like it has no signs of stopping. This lesser-traveled Middle Eastern country is one of the most undiscovered places that everyone must visit at least once. You may have to jump through some hoops to get a visa for the country, but we promise you it’s worth it. This burning hole has earned a series of nicknames including “mouth to the underworld.” Just make sure you don’t get too close or else you’ll never get out. It’s one of those phenomena that travelers can’t stay away from (via Hostelworld).
