Mysterious Underground Tunnels and Bunkers for the Adventurous Traveler

19. The Greenbrier Bunker – America’s Best-Kept Cold War Secret

Hidden beneath the luxurious Greenbrier Resort in West Virginia is a secret that was kept under wraps for over 30 years: a massive underground nuclear fallout bunker built for members of the U.S. Congress. Constructed during the Cold War, the bunker was fully stocked with supplies, dormitories, and communication facilities, designed to serve as the emergency headquarters for the U.S. government in the event of a nuclear attack. The facility remained classified until a journalist exposed it in 1992, leading to its decommissioning. Today, guided tours take visitors through the bunker’s reinforced doors, revealing a chilling reminder of the era’s doomsday preparations.
