One for the Bucket List
Dare to venture on the Wild Cave Tour. Ready for slithering through openings possibly as thin as 9 inches? Cure you're claustrophobia and fear of the dark all at once. Although the park offers more than a dozen tours for all ages and degrees of monster-under-my-bed skittishness, the Wild Cave Tour is for the most adventurous -- and is considered very difficult.
You'll have to gear up in helmets, boots, headlamps and kneepads to climb in passageways seen on no other tours. The six-hour adventure winds through Cleaveland's Cabinet, Thorpe's Pit and Cathedral Domes, among other amazing features, and ensures plenty of twists, crouching, crawling and inevitable jaw-dropping. Reserving the tour is highly recommended, as well as speaking with a park representative beforehand to go over safety restrictions.
Seasons and Hours
The park's visitor center is open year round, but the park is closed on Christmas Day. Daily schedules vary for the park's 10+ cave tours. Reservations are recommended for the Wild Cave Tour, Introduction to Caving and Trog, especially during peak summer months. More info about tour schedules.
Time Zone Note: Mammoth falls just west of the time zone line that splits Kentucky. The park is in the Central Time Zone, not the Eastern Time Zone -- many visitors driving in from the east forget this.
Several roads lead into the park, from all directions. Take 70/255 from either east or west to merge onto the South Entrance Road that leads to the visitor center. Two ferries operate to transport vehicles across the Green River, which bisects the park. To reach Mammoth Cave and the visitor center, you only need to cross via the Green River Ferry if you are driving into the park from the north entrance on 1352. More info on the ferries.
