Meramec Caverns is a huge underground cave near Sullivan filled with amazing rock shapes. Guides lead visitors on walking tours deep inside the cool, dark tunnels.
It is famous for its towering stone curtains and colorful lights that make the cave sparkle. Legend says the outlaw Jesse James once hid in these very caves.
Water dripping for thousands of years built stalactites hanging from the ceiling and stalagmites rising from the floor.
Deep inside, the cave stays about 60 degrees all year, so bring a jacket even in summer.
Stories say Jesse James used the winding caves as a secret hideout many years ago.
