Mammoth Cave National Park, Show cave in Edmonson County, United States.
The limestone cave system extends through 400 miles of underground passages, forming chambers and natural formations across multiple levels beneath Kentucky.
Native American tribes first discovered the cave system 4000 years ago, leaving behind artifacts and evidence of their exploration in the dark passages.
Stephen Bishop, an African American guide in the 1840s, created detailed maps of the cave system and discovered numerous passages during his explorations.
The National Park Service provides guided tours at different difficulty levels, allowing visitors to explore sections ranging from easy walks to challenging adventures.
The cave maintains a constant temperature of 54°F (12.2°C) throughout the year, creating conditions for specialized underground species to develop without eyes.
