Aokigahara is a forest that lies at the base of Mount Fuji, less than 100 miles west of Tokyo. It is known as "sea of trees" because of the high density of trees. This forest is the number one suicide spot in Japan, and is the second highest suicide place next to the Golden Gate Bridge. Entrances would include messages as "Your life is precious" or "Think of your family." The author,The Complete Manual of Suicide” by Wataru Tsurumi described the Aokigahara as the perfect place to commit suicide and even described which parts of the forests are less circulated so the bodies cannot be found later on.
The Island of dolls sounds like some sweet escape. La Isla de las Muñecas, a real place located in a southern borough of Mexico City on a man-made island that for decades has been home to hundreds of dilapidated dolls. 50 years ago,Don Julián Santana, a local farmer saw a little girl drown in the canal and her spirit began haunting the place. Terrified, Don Julián started collecting dolls to protect himself from her ghost. He gathered them from trash heaps and hung them around the island like creepy Christmas ornaments. Over half a century, he collected more than 1,500 of these little horrors. The oldest (Santana) is still there, hanging in a shed by the entrance. From afar, it looks like the decaying corpse of a child.

The mines of Paris consists of several abandoned mines.The tunnels stretch for close to 600 kilometers throughout the Parisian underground, and most of them are unmapped. Saying it is easy to get lost is an understatement. It is nearly impossible not to get lost. Many parts of the catacombs are hundreds of feet below street level. Some hallways are flooded, or are so narrow you have to crawl through them. There are holes that drop hundreds of feet, and manholes that are unreachable, luring unwary urban explorers in with false promises of freedom.
