12 Most Mysterious Places On Earth To Explore

Door To Hell, Turkmenistan: The Gates of Hell crater was created in 1971 when a Soviet drilling rig accidentally punched into a massive underground natural gas cavern, causing the ground to collapse and the entire drilling rig to fall in. Having punctured a pocket of gas, poisonous fumes began leaking at an alarming rate. Amazingly, despite the crater's foreboding name and ever-present flames, people still trek into the desert to witness the site in all its blazing glory. The nearby desert has become a popular place for wild camping.
