Mammoth Cave is quite literally mammoth. It is the longest cave system in the world, and its lengthy 390 miles are located in central and south Kentucky, and it is known as a part of the Green River Valley. However, that number is bound to change in the near future as researchers continue to discover new branches of caves.
Mammoth Cave is home to some bizarre yet fascinating rock formations. Take a trip to the Frozen Niagara entrance and take pictures of the most photographed part of the cave system. Take a cave tour and explore the Rotunda and the Snowball rooms, or squeeze through passages such as Fat Man’s Misery and Tall Man’s Misery. Even visit the Lost River Cave, a section of Mammoth Cave through which you will experience an underground lake tour, ducking under the low ceiling.
For overnight stays, try camping on one of the various campgrounds located in the park. There are many modernized ones while more experienced campers can take the opportunity in the primitive campgrounds.
