The natural entrance to Mammoth Cave - what looms underground? Find out!
Mammoth Cave National Park preserves the cave system and a part of the Green River valley, the hilly country of south central Kentucky. This is the world's longest cave system, with more than 365 miles explored.

An early tour guide and nature enthusiast, Stephen Bishop, called the cave a "grand, gloomy and peculiar place," but its vast chambers and complex labyrinths have earned its name: Mammoth.

Mammoth Cave National Park was established in 1941 to protect the unparalleled underground labyrinth of caves, the rolling hilly country above, and the Green River valley. Since then, ongoing study and exploration have shown the park to be far more complex than ever imagined, hosting a broad diversity of species living in specialized and interconnected ecosystems. The park's challenge is to balance these remarkable and sometimes fragile living networks with the public's enjoyment of them. The key to that balance is knowledge, and the park's new environmental monitoring programs will provide that understanding.

There is so much to do at the park. From cave tours to river roat rides. From camping to woods exploration and nature watching. You will not be disappointed coming here. Because the great outdoors in Kentucky are not boring, rather they are enlightening and exciting! You will walk away from a vacation to this outdoor destination feeling refreshed, renewed and respirited!

Camping at the Park

There are few better ways to discover the pleasures and curiosities of the sunlit side of Mammoth Cave National Park than to camp among the trees or by the waters. The park offers camping in three developed campgrounds and in more than a dozen primitive sites in the backcountry and along the Green and Nolin Rivers. Use the links to find out about the different campgrounds. The table below will help you choose the one that's best for you. Also be sure to check out the Campground Regulations.

Firewood from a number of states is quarantined due to an insect infestation by one or more insect pests (e.g. the Emerald Ash Borer) that is devastating certain tree species. Please help protect our forests from these destructive pests and do not bring firewood into the Park.

The Entrance to the Mammoth Cave - Courtey of National Parks Service and Mammoth Cave NP

Here's the description of one of tours of the cooler caves, the River Styx Cave:

"Trace the stages of cave development from solid layers of limestone into the world’s longest known cave system. Follow the course of the water from ridge top to river bottom and witness the persistence and power required to create this geologic marvel. Experience some of the largest continuous canyon passages on the planet, smooth elliptical tubes and beautifully sculpted shafts. Working your way to the cave’s lowest level you’ll be able to peer into the cold river water that still hollows out the limestone and lengthens the cave system. Understand the processes of both the surface and subsurface and realize how all of the pieces of the puzzle fit together to make the story of the world’s longest cave unfold before your eyes." - From NPS.  Sounds pretty spectacular, huh!

Sixty miles of trails north of the Green River are open for horseback riding. Day-use horseback riders can park trailers:

  • At Lincoln Trailhead
  • Across the road from the Maple Springs Campground bulletin board
  • At Maple Springs Trailhead
  • 1/4 mile north of Maple Springs Campground At Good Springs Church.
  • Please note that Sal Hollow Trail is closed to horses.

A free trail map is available in the Backcountry Map & Guide, the park newspaper, and other maps and guides sold at the Visitor Center show topographic features and trails in greater detail.

Several rules apply to all horseback riders using the park:

  • When hikers and horses meet, horses must be slowed to a walk and hikers must remain quiet.
  • Always hitch horses more than 100 feet away from designated campsites, trails or water sources.

If you plan to camp overnight in the park with horses, the following information applies: Overnight horseback riders can use Maple Springs Group Campground, located five miles from the Visitor Center and three miles north of the Green River Ferry. The most direct route requires crossing the Green River Ferry, a free ferry with an 8 ton load limit. However, some vehicles (i.e. long horse trailers) cannot be ferried solely because of the length or ground clearance. The Green River Ferry is open daily from 6:00 AM - 9:55 PM (except when closed for repairs or during hazardous river conditions). Alternate routes via state and county roads are available and may be more practical for trailers.

Maple Springs Group Campground has seven sites, and four of them are equipped for horseback riders. Specific rules apply to horseback riders using campsites at Maple Springs:

  • Sites 1, 2, 3 and 4 at Maple Springs are designed to accommodate horses. Do not use any of the other Maple Springs Campground sites if you are camping with horses.
  • Park vehicles only at the gravel spaces located at each campsite. If you need additional parking, use the parking area across the road from the bulletin board.
  • Dispose of horse manure by scattering it in the woods at least 200 feet behind the campsites.
  • Picket areas are located behind sites 1, 2, 3 and 4. You must use these facilities to tie up your horses. Never tie horses to trees.
  • The central grassy area is for amphitheater and recreational use only. Do not let your horses use the area.
  • Do not allow your horses near the water spigots in the campground. You must pack water to your horses for drinking or bathing.
  • Water hoses can be attached to water spigots temporarily, but do not leave hoses attached.
