Visiting the national parks in North America has become a favorite part of our Airstream travels. So when we traveled through central Kentucky, I knew we wanted to stop at Mammoth Cave National Park. We unfortunately made the mistake of not booking our tours in advance and therefore we were only able to book one tour. So to help you not make the the same mistake we did, below is everything you should know to have a great time, including the best time to visit Mammoth Cave National Park.

When is the best time to Visit Mammoth Cave National Park?
For the least amount of crowds, the best time to visit Mammoth Cave National Park are winter months between November and February. I think fall has the best weather and its really pretty when all the leaves are changing colors. However there are fewer tours available at those times. Summer is peak season and offers the most variety of cave tours and times but also has the most crowds.
How much time should you spend at Mammoth Cave National Park?
Depending on the season, with one to two days at the park, you can go on multiple cave tours and also hike the trails.
What time zone is Mammoth Cave?
Mammoth Cave is in the Central Time Zone. So if you purchased cave tour tickets in advance, make sure you confirm your tour time.

The park is open year-round, with the exception of Christmas Day. This is the one day of the yer the park is closed. Cave tours are NOT available on Christmas Day.

No. You must be on a cave tour to enter the cave. There is a self-guided tour that is sometimes available however the remaining Mammoth Cave tours are guided. The costs range from $6 to $60 for a cave tour.
Is it cold inside Mammoth Cave?
Mammoth Cave stays a consistent temperature of 54ºF year round.
What should you wear at Mammoth Cave?
Plan to bring layers especially if you get cold easily. I wore a headband because my ears always get cold. Keep in mind, if you are visiting in the summer months, it is very warm outside and will be cold in the cave. And in the winter it can freezing outside and slightly warmer in the cave. Also plan to wear good walking shoes.
Is the park pet-friendly?
Yes. Pets are permitted on trails, multi-use paths and park roads. They must be kept on a leash. Pets are not permitted in buildings and on cave tours.
Is there cell service at Mammoth Cave?
That depends on your carrier, so it is a maybe. At the visitor center we had service with T-Mobile. In the campground, our phones did not get service but our Verizon hot spot worked well.
