Mammoth Cave National Park preserves the cave system and a part of the Green River valley and hilly country of south central Kentucky. This is the world's longest cave system, with more than 365 miles explored.
Leashed pets are permitted in the park, but are not allowed in the caves or Visitors' Center. Leashes must be no longer than six feet. There are accomodations here that are pet-friendly (Woodland Cottages), and the hotel maintains a kennel. Call 270-758-2225 for availability.
