The Adventure
Our summer camping trip in July 2025 included visits to two National Parks. To make the most of the hot and humid weather, we headed underground—why not explore the longest cave system in the world?
The Ordeal
Not all campgrounds offer electric hookups, and not all campers—like ours—cannot run air conditioning off-grid. In July’s intense heat, this made camping a bit of a challenge.
Tips
We booked two cave tours for the same day: the Historic Tour at 10:00 a.m. and the Domes and Dripstones Tour at 2:15 p.m. Both were led by knowledgeable and engaging park rangers. We highly recommend taking both tours—they offer different perspectives on the cave system and are well worth your time.
Visiting the Mammoth Cave National Park begins at the visitor center, which serves as an essential first stop. It’s both educational and informative, offering an introduction to the park’s history and natural features. The center also acts as the launching point for all tours. While you can make tour reservations there, it's best to book in advance to ensure availability. Be sure to explore the exhibits—they provide valuable context and help you prepare for your cave experience.
On the Historic Tour, our park ranger shared captivating stories about the cave’s early uses, from saltpeter mining during the War of 1812 to early exploration and candlelit tours. We walked through vast chambers such as the Rotunda and Gothic Avenue, where graffiti from centuries past still marks the walls. Over the course of two miles underground, we traveled deep into the cave system—hundreds of feet below the surface.
The Domes and Dripstones Tour showcased some of the cave’s most visually stunning features. We descended steep staircases into towering vertical shafts, known as domes, then moved into ornate passageways adorned with stalactites, stalagmites, and shimmering flowstone. A standout moment was the breathtaking Frozen Niagara formation. This tour offered a dramatic contrast to the drier, more historic sections of the cave.
Camping at Mammoth Cave National Park Campground puts you just a short walk from the visitor center and the cave tour entrances. The campground offers a mix of tent and RV sites, complete with restrooms and picnic tables. RVs are welcome at selected sites, with the two VIP sites offering full electric and water hookups. A convenient dump station is located at the nearby service center.
Beyond the campground, adventurers can explore 14 miles of scenic hiking and biking trails that wind through the park’s stunning landscape.
