The list is an extensive one, providing readers with 29 unique and scary adventures. Amongst the options that Nat Geo offers are exploring limestone caverns in Mexico that are filled with bats, visiting a national park in Bolivia that is overrun with termites, and visiting a series of caves that are filled with bones in Mali. Other eerie destinations include a hike through Germany's Reinhardswald Mountains where many ancient fairy tales are believed to have taken place and exploring Joshua Tree National Park after dark.
As you would expect from National Geographic, each of the items on the list includes a great photo to help set the stage. Unfortunately, not all of the entires on this slideshow do a great job of telling you exactly why this place is creepy enough to deserve a mention here. This seems to be a reoccurring theme on the Nat Geo website in recent months, with articles that lure you in with nice images an intriguing headlines, but don't always deliver the goods in terms of substance. Still, with a little research, it becomes clear why many of the entities on the "creepy list" belong there.
