Hoia-Baciu Forest, Romania Alamy Hoia-Baciu Forest, Romania

From the moment a military technician captured a photograph of a “UFO” hovering over the forest in 1968, Hoia-Baciu has gained paranormal notoriety around the world, with some believing it to be a portal that causes visitors to disappear. Those who have passed through the forest without being zapped into another realm have reported rashes, nausea, and feelings of anxiety, according to The Independent. Known as the “Bermuda Triangle of Transylvania,” the spooky curved trees that populate the forest just add to the eerie atmosphere.
