Adventure Underground at Meramec Caverns

If you have driven around Missouri much at all, you have certainly seen the billboards and painted barns advertising Meramec Caverns. This attraction is a mix of natural wonder and road trip kitsch. As the cave is a constant 58 degrees year round, it also provides a perfect place to take a tour on a steamy summer day. Located about an hour west of St. Louis, the cave and other on site attractions make a great road trip destination.

History

Osage Indians first led a French explorer to the cave in 1720. The French explorer discovered that the cave contained saltpeter, a key ingredient in making gunpowder. Disputes arose over the years of control of the cave and this mineral until Confederate troops destroyed a Union-held gunpowder facility inside of the cave.

Starting in the 1890s, the cave gained popularity as a social attraction. Visitors could escape to the coolness of the cave for social gatherings. Over the years expeditions in the cave led to the discovery of more levels and chambers. One of these discoveries led to evidence that Jesse James once used the cave as an outlaw hideout. As the popularity of the cave rose, it also was used as the site of several TV shows and movies.
