19 Most Scary Places On Earth. #13 Will Give You Goose Bumps

4. Sulphur mine in Kawah Ijen volcano, Indonesia

Kawah Ijen is an active volcano in Indonesia that is mined for sulfur. Miners scale 2,600 meters to the crater, then down to the shore of a 200-meter-deep crater lake of sulfuric acid, where they retrieve heavy chunks of pure sulfur to carry back to a weighing station. They do all this without any protective masks or gear.

5. Mariana Trench, Pacific

Mariana Trench is currently the deepest known point on earth. With its crushing pressures and pitch black waters, it is deeper than average cruising altitude of commercial airliners and harbors some of the strangest life form known to men.

6. The Wall, St. Croix, U.S. Virgin Islands

Not one for the divers afraid of heights! The Wall is a two mile vertical drop made even scarier by the crystal clear waters that allow you to see in to the abyss.
