Beyond the caves, the park also offers short or extensive trails to explore the area above ground. The area is also home to other park options within a 30-minute drive offering water parks, zip lines, and horseback riding through the area.  Below, our National Park Visitors Guide highlights some of the activities Mammoth Cave National Park has to offer.

    Mammoth Cave

    The world’s largest known cave system is something worth repeating. The nearly 400 miles of explored caverns are just the beginning of what is believed to be hundreds of miles of cave systems still to be explored. The cave is well lit for most tours, but guides will sometimes humor visitors with a brief demonstration of the absolute darkness of the caverns (with a warning ahead of time of course).

    Hiking Trails

    The park offers over 60 miles of trails on the northern side of the park. The park's location along the outer edge of the Appalachian Mountains provides visitors with views of dense forests and dynamic hikes from moderate to advanced-level experiences. The trails are most popular in the spring and fall when the weather is cooler, and the trails are the most photogenic.

    Horseback Rides

    Horse rides are a great way to see more of the park in less time. The guides are rigorously trained and do an incredible job from horse riding basics for beginners to information and history along the tour. We recommend going for an hour so that you have enough time to enjoy the scenery and the horses don’t get too tired on the trails.

    Green River

    Canoe or kayak along the river and relax in the quiet wilderness. You can bring your own or rent one and you can expect plenty of areas along the banks to stop and rest or enjoy the park along the river. The water comes from deep inside the cave so it’s incredibly clean, and the staff is informative and helpful making sure you enjoy your time on the river.


    The park has a lot of options for camping inside the park. The majority of the camping sites are along the Green River on the southern side of the park and have facilities for guests. The site lots are generally spread out allowing a lot of space for you and your family or group to enjoy yourselves without disturbing neighboring campers. We recommend booking your campsite ahead of time especially in the peak summer months.

    When to go to Mammoth Cave National Park?

    Mammoth Cave National Park is open to visitors for cave tours, trail hiking, horseback riding, to name a few activities available in the park year-round. The park’s peak season is during the summer months when the weather can be hot above ground but offers a lot of opportunities for shade or cover from the weather. The wooded hiking trails provide beautiful backdrops and are wonderful opportunities for photographs and seeing wildlife throughout most of the year as well. In the winter expect there to be fewer tours operating but generally, they are also less crowded than the peak season from late spring to early fall. You can expect the caverns to be damp once inside, so we recommend you bring warmer clothes than you would wear. The cavern's interior passageways are generally stable year-round and stay between the mid-50’s to lower-60's F.

    Must-Have Things to Bring to Mammoth Cave National Park

    The park is massive above and below ground but offers visitors a lot of options for facilities and supplies. The park is well-established, and the guides and volunteers are knowledgeable and eager to help.


    Whenever traveling it’s always wise to have water. The park has plenty of water fountains and access to clean water, but it’s something you never want to run out of on a hike. List of Parks always recommends bringing a full thermos for each person if you’re planning on hiking the trails. It's best to talk to the guide before bringing bags into the cave because you may need to go through tight spaces depending on the tour.


    The park has its own snack shops and plenty of options nearby outside of the park but as most parents know - you always need snacks. It’s a good idea to check cave tour information for suggestions on what supplies they suggest bringing based on the tour you select.

    Park Maps

    Mammoth Cave is an established and visitor-centric park with internet capabilities, but it has limitations because of its size. The trails are marked but you’ll want a map if you decide to venture farther from the centralized visitor center. You may have phone service at the entrance of the cave, but you can expect no service throughout most of your tour inside the cave.

    Tour Tickets

    It’s not required, but we (and as you'll see on the park website) highly recommend you buy tickets for your cave tour before you arrive. For the safety of visitors, the park is currently reducing tour frequency and the number of visitors allowed to go on each tour. This will also give you more time to plan and prepare for your exact needs on the tour you choose.

    Jacket and Cold Weather Attire

    Make sure you check the weather before visiting the park. We recommend always having a jacket or something to keep you dry in your bag when going on a cave tour. Once within the cave, the temperature stabilizes but it's still relatively cool and you’ll want to dress appropriately so you can have a more enjoyable tour experience. You can always take your jacket off as the temperature warms as you come back to the cave entrance.

    Proper Footwear

    Whether you’re planning on a day exploring the cave or hiking, try to bring hiking boots or shoes with some grip. Even though most of the trails and paths are well maintained, the cave can be dark, and the stone can be slippery and are much safer and enjoyable with some traction.

    Bug Spray

    In the spring and summer we recommend you have plenty of bug spray if you’re spending significant time above ground in the park. The caves are generally not an issue for bugs, but no one wants to be in the middle of the trail or wake up after the first-night camping covered in bites.

    Extra Provisions

    Water and food are essentials, and although you don’t have to have toilet paper, you never want to be in a situation where you are without it. Also, reusable items like plastic bags for collecting your trash and taking it outside the park. Masks are also a greatly appreciated item to bring, your tour guides and other visitors will appreciate you for it.
