20 Best Caves in the United States

The contiguous United States is home to more than 45,000 caves and caverns, formed by erosion and other geological processes over the span of millions of years. Though many of the country’s caves were historically used by indigenous populations as burial or wintering sides, they were rediscovered by Europeans in the 19th century due to the westward expansion of pioneers, with many opened as public show caves to spark the nation’s explorer spirit and creative imagination. Today, the United States is home to some of the world’s most famous caves, including Mammoth Cave, the world’s largest cave system, and the 6,400 caves of Missouri, popularly known as the “Cave State.” These 20 caves are among the most spectacular of their kind in the country, noted for their breathtaking underground waterfalls, unusual speleotherm formations, and rich fossil and archaeological sites.
