“Plummet far into the inky blackness that is the world of caving and penetrate worlds which have lain undisturbed for thousands of years”

Embark on an extraordinary journey into the underworld of caves. Beneath our sunlit world lies an unknown universe of breathtaking caverns, treacherous passageways, and absolute darkness.

Join a National Geographic expedition to document for the first time on film the splendours of the world’s most exotic new cave: New Mexico’s Lechuguilla. Relive the excitement of those cavers who, in 1986, first penetrated Lechuguilla, which had lain undisturbed for thousands of years. Marvel at the pristine beauty of gypsum chandeliers, gnarled calcite columns, and jewel-like lakes.
Then, join the 1972 expedition that stumbled upon a passageway that linked the Mammoth and Flint Ridge Cave systems, creating the longest cave network in the world.
And relive thrilling discoveries and heart wrenching tragedies in caving history. You’ll view caves in a whole new light once you explore Mysteries Underground.

Closet spelunkers, don your helmet flashlights and rejoice! Mysteries Underground from National Geographic is your personal tour guide of the vast worlds that exist right under your feet.
