Budget traveling around the world for two years

Mammoth Cave National Park


  • The longest cave system in the world
  • A variety of cave tours and guided walks
  • Tranquil above-ground forest and hill country

When To Visit: Year-round

Climate: Highly variable with possibility of storms year-round. Very rainy in spring. Fairly warm year-round.

Location: Southern Kentucky – 1.5 hours south of Louisville and north of Nashville

Mammoth Cave is a world wonder with over 400 miles of cave and more yet likely still unmapped. Stepping inside the cave will take you back in time and expose you to a level of darkness that is difficult to come by on the surface. After you explore the caves, you can enjoy a nice hike in the park’s Green River Valley, a wonderful showcase of Kentucky’s hill country.
