Dark Star Cave
In a remote corner of the Baiyun Tau mountains on the Uzbek-Afghan border sits the most dangerous cave in the world, the Dark Star Cave. This huge cave system sits in an isolated region in Uzbekistan and features everything from huge waterfalls to frozen lakes.It’s no wonder that the cave has been called the “Underground Everest” by many, as the freezing interiors of the cave stretch on for miles. Until now, 8 expeditions have explored nearly 11 miles of passages in Dark Star, the deepest of which is around 3,000 feet below the surface of the earth.
