Forget the Grand Canyon – Arizona’s real treasures are hidden underground!
Grab your flashlight and sense of adventure as we spelunk through the state’s most captivating caverns.
1. Kartchner Caverns State Park (Benson)
Welcome to nature’s own Sistine Chapel!
Kartchner Caverns is like the Louvre of limestone, minus the crowds and with 100% more bat guano.
This subterranean wonderland was discovered in 1974 by two cavers who must have thought they’d stumbled into a geologist’s fever dream.
As you descend into the cave’s depths, you’ll be greeted by a forest of stalactites and stalagmites that would make Michelangelo weep with envy.
The cave’s constant 70-degree temperature makes it a perfect escape from Arizona’s scorching summers.
It’s like nature’s own air conditioning system, complete with stunning rock formations instead of boring vents.
2. Colossal Cave Mountain Park (Vail)
If Kartchner Caverns is the Louvre, then Colossal Cave is the wild, eccentric cousin who lives in a treehouse and makes art out of recycled bottle caps.
This cave system is a maze of twisting passages that would make a minotaur throw up its hands in frustration.
Legend has it that train robbers once used Colossal Cave as a hideout.
I can’t help but imagine them stumbling around in the dark, bumping into stalactites and cursing their life choices.
Today, you can take guided tours without the risk of running into any disgruntled outlaws (though I can’t guarantee you won’t encounter some overly enthusiastic spelunkers).
The cave’s “Civilian Conservation Corps Ladder” is a testament to human ingenuity and questionable safety standards.
It’s a reminder that sometimes the best adventures come with a side of “What were they thinking?”
3. Grand Canyon Caverns (Peach Springs)
Don’t let the name fool you – these caverns are about as related to the Grand Canyon as I am to Brad Pitt (which is to say, not at all).
Located 210 feet underground, this is the largest dry cavern system in the United States.
It’s so dry, in fact, that you might want to bring some lip balm.
Your lips will thank you, even if they can’t speak because they’re too busy being amazed.
The caverns boast a rather unusual feature: a fully equipped underground suite where you can spend the night.
It’s perfect for those who’ve always dreamed of sleeping in a cave but didn’t want to deal with bears or questionable hygiene standards.
4. Peppersauce Cave (Oracle)
Peppersauce Cave is the wild child of Arizona’s cave scene.
Unlike its more domesticated cousins, this cave is undeveloped and unsupervised.
It’s the spelunking equivalent of being let loose in a candy store after hours – exciting, potentially messy, and not recommended for the faint of heart.
The cave got its spicy name from a prospector who left a bottle of pepper sauce near the entrance.
I like to imagine him saying, “Future generations will remember me for this culinary contribution to cave exploration!”
Little did he know, he’d be immortalized in the most unexpected way.
5. Cave of the Bells (Sonoita)
Despite its musical name, you won’t find any bells in this cave.
What you will find is a subterranean labyrinth that would make the Phantom of the Opera green with envy.
The cave is known for its pristine formations and crystal-clear pools that reflect like nature’s own funhouse mirrors.
Access to Cave of the Bells is restricted to protect its delicate ecosystem.

It’s like the VIP section of the underground world – exclusive, mysterious, and probably with better drinks (if by drinks you mean pure, untouched groundwater).
6. Lava River Cave (Flagstaff)
Imagine walking through a tunnel formed by molten rock.
Now imagine doing it without sweating profusely or bursting into flames.
Welcome to Lava River Cave!
This mile-long lava tube is a testament to nature’s ability to create awesome things while also trying to kill everything.
The cave maintains a cool 40 degrees Fahrenheit year-round, making it the perfect spot to chill out (literally) during Arizona’s sweltering summers.
It’s like nature’s own walk-in freezer, but with more interesting geology and fewer frozen pizzas.
7. Coronado Cave (Hereford)
Named after the Spanish explorer Francisco Vásquez de Coronado, this cave is like a time capsule with stalactites.
It’s a 600-foot-long cavern that you can explore without a guide, which is either thrilling or terrifying, depending on your comfort level with dark, enclosed spaces and the possibility of getting lost.
The cave’s entrance is reached by a steep half-mile hike.
It’s nature’s way of saying, “If you want to see my underground wonders, you’re going to have to work for it!”
Consider it a warm-up for your subterranean adventure.
8. Apache Death Cave (Two Guns)
With a name like “Apache Death Cave,” you know you’re in for a cheery experience.
This cave, located in the ghost town of Two Guns, has a history more dramatic than a telenovela.
It was the site of a tragic conflict between Apaches and Navajos in 1878.
Today, the cave is part of a larger complex of ruins that make up the abandoned town of Two Guns.
It’s like a real-life version of a post-apocalyptic video game, minus the mutant creatures (we hope).
9. Onyx Cave (Dragoon)
Onyx Cave is the jewelry box of Arizona’s cave collection.
Its walls are lined with beautiful onyx formations that shimmer in the light of your headlamp.
It’s like being inside a giant geode, only with more crawling and less gift shop potential.
The cave is on private property and access is restricted, making it the secret garden of the underground world.
If you manage to get permission to visit, consider yourself one of the lucky few to witness this hidden gem.
10. Tonto Natural Bridge State Park (Payson)
We’re ending our subterranean journey with a grand finale – the largest natural travertine bridge in the world.
Okay, it’s not technically a cave, but it’s too cool to leave off the list.
It’s like the overachiever of geological formations.
Standing 183 feet high over a 400-foot-long tunnel, this natural bridge is a testament to the power of water and time.
It’s like nature’s own version of a highway overpass, only much more impressive and with significantly less traffic.
From bat-filled caverns to lava tubes, Arizona’s underground scene is more happening than most cities’ nightlife.
