Mammoth Cave National Park

A ranger explains Mammoth Cave in the vast passage known as Broadway. Rotunda, one of the cave's largest rooms, is just ahead.
Rolling hills, deep river valleys, and the world's longest known cave system. Mammoth Cave National Park is home to thousands of years of human history and a rich diversity of plant and animal life, earning it the title of UNESCO World Heritage Site and International Biosphere Region.
