A tributary of the Ohio River, the scenic Green River traverses this well-forested, rugged terrain for 25 miles. More than 80 miles of back-country trails, all of which can be used for hiking and some available for horseback riding and mountain biking, run along the river's bluffs, ridges and valleys. Biking trails also are available. In the northwestern section of the park is the 7-mile-long Nolin River. Several scenic driving tour routes wind through the park.
Within the park is Mammoth Cave, which has yielded archeological evidence of humans approximately 5,000 years ago. During the War of 1812 the cave furnished saltpeter used to manufacture gunpowder.

Mammoth Cave contains more than 400 miles of underground passages charted on five levels. Said to be the longest cave system known, it was hollowed out by the seepage of ground water and the flow of underground streams. The cave contains diverse passageways, some of which contain remnants of 5,000-year-old stick cane torches, woven sandals and names written on the cave walls by guides during the 19th century using candle smoke.
