Mammoth Cave National Park

Share your visitation dates


Four thousand years ago, Mammoth Cave was discovered by man for the very first time. It was quite a discovery, but for thousands of years afterward, it was left untouched. It wasn’t until the late 18th century that people began to take interest in it once again.

Mammoth Cave National Park, established in 1941, is known for the world’s longest cave system--400 miles of it that has been explored so far. The caves are the biggest attraction, but that’s not all you’ll find here. This park also features the Green River Valley and beautiful rolling country hills. There are also two rivers - Green River and Nolan River - that will provide you with excellent opportunities for canoeing, kayaking, fishing, and much more. With everything that nature has to offer, you can be sure that you’ll make stunning new discoveries when you go RV camping here.

The weather in Kentucky and within the park tends to be moderate. Summers are pretty warm, winters are fairly cool, and about 46 inches of rain is expected each year. Most of this rain falls during the springtime. If you go in the summer, be prepared for weather that’s brought up by the Gulf of Mexico. No matter what time of the year you wish to visit this park, you can be guaranteed that it’ll be open. This park stays open year-round, with the exception of Christmas Day. Anytime is a good time to bring your RV to Mammoth Cave National Park.

Transportation in Mammoth Cave National Park


It has been found that GPS and Google Maps tends to take a long way around to get into the park. There are two ways that work best. If you’re coming from the north, you can take Interstate 65 to Exit 53, then turn right onto KY-70 and stay on 70/255 until you arrive. If you’re coming from the south, you can take Interstate 65 to Exit 48, then turn left on KY-255 and stay on 255 until you get to the park. Once here, there are various roads and parkways to take you through the park.


There are a few sites available for RV campers at the park. There is also parking at the visitor center and at overlooks on the parkways. If you can, take the car instead when traveling throughout the park. This way, it’s both easier to get around, and there is more room for other visitors.

Public Transport

There are other ways that you can get around the park besides driving a car. For instance, you can take the Green River Ferry or the Houchin Ferry. You can also take your bicycle through the certain parts of the park, or even go horseback riding if you’re up for it.
