Top Caves to Explore in the U.S.
✰✰ PRO TIP ✰✰ Anytime you visit a cave, always wear sturdy closed-toe shoes with good traction. The cavern floors are oftentimes slippery.
Carlsbad Caverns – New Mexico
Carlsbad Caverns cave system has more than 119 limestone caves that are outstanding in the profusion, diversity, and beauty of their formations.
Hence, why it’s designated as one of America’s National Parks.
And, if you’ve never been, just let me tease you by saying it’s an absolute show stopper. Because Carlsbad is one of our ultimate favorite caves to explore in the U.S.!
With it’s impressive stalactites that cling to the ceiling of the underground chamber, the Big Room, it’s no wonder it’s also a favorite of other caving enthusiasts.
Depending on if you decide to hike up or down, you gain or lose about 750 feet which is equivalent to stair-stepping a 75-story building.
The Carlsbad Caverns cave hike takes, on average, one hour to complete the 2.5 mile distance.
As you see, this cave tour isn’t exactly for the faint at heart, breathless, and even weak in the knees.
And we mean that quite literally. Visitors with physical, physiological, respiratory or heart conditions will unfortunately have to sit this cave tour out.
But this Chihuahuan Desert southern New Mexico cave system isn’t just all about what’s down in the National Park’s belly.
Above ground is just as beautiful as what’s below your feet. Walnut Canyon Desert Loop is a drive with spectacular desert views.
And, Rattlesnake Springs, a desert wetland, attracts reptiles and hundreds of bird species.
It has high ancient sea ledges, deep rocky canyons, flowering cacti, and a vast variety of desert wildlife.
Important to note though, due to Carlsbad Caverns National Park’s popularity, reservations are required to enter the park.
You’ll need to secure your timed entry in advance.
Then, bring your ID, National Park Pass or pay the entrance fee when you arrive. Reservations are not available at the park.

Wind Cave National Park – South Dakota
I tell everyone who is visiting the Black Hills of South Dakota that it’s an absolute must to visit Wind Cave National Park!
Wind Cave is known for being the world’s densest cave. It contains 95% of the entire world’s honeycomb-shaped calcite formations known as boxwork.
Boxwork is formed when dissolved calcium carbonate crystallized in cracks in surrounding rock. The surrounding rock then erodes away and leaves the boxlike calcite crystals.
But also historically, Wind Cave is sacred ground of the Lakota tribes.
According to NPS History,
“Regarded as sacred by American Indians, the cave was not found by settlers until 1881, when two brothers, Jesse and Tom Bingham, heard a loud whistling noise.
The sound led them to a small hole in the ground, the cave’s only natural opening.” Hence, why it’s name is ‘Wind Cave’.
Topside, Wind Cave’s pine forests and gentle prairie hills are home to bison, elk and pronghorn antelopes. There are some great hiking trails including Rankin Ridge, with views of the Black Hills.
Before or after your visit to Wind Cave: Take a trek to Deadwood, South Dakota (75 miles) to learn about the Story of the American Bison. You don’t want to miss this!
✰✰ PRO TIP ✰✰ Camping near Wind Cave is at Elk Mountain Campground, in hills of ponderosa pine forest and prairie, has 61 first-come-first-served campsites (fees); 48 of which are RV friendly from April through October. Backcountry camping is also allowed with required permit.

And topside, you can also check out the Native American rock art sites, historic battlefields and campsites.

Moaning Caverns – California
In the heart of California’s gold country near the town of Vallecito, Moaning Caverns awaits a cave hiker’s discovery.
However, artifacts and skeletal remains date back to ancient cave dwelling people. Of the archeological finds in the cave, a mother-of-pearl necklace estimates to be more than 8000 years old.
But how did Moaning Caverns get its’ name? It’s been said during the gold rush in the 1840’s that miners heard a peculiar moaning sound luring people to the cave entrance.
Unfortunately, the moaning sounds dissipated when the grounds crew widened the access.
Today, Moaning Caverns’ staircase has 144 stairs and spirals around 7½ times which enables hundreds of thousands of visitors to enjoy the adventure of descending deep into the largest single cave chamber in California.
