9 Crazy Cool Caves You’ll Want To Explore ASAP
Explore beneath the earth’s surface in these stunning caves around the world. From iridescent caverns to glowing hot springs, these natural formations are worth a deep dive. Our picks for the coolest caves in the world will inspire you to grab your flashlight and get subterranean!
1. Waitomo Glowworm Caves, New Zealand
The Waitomo Caves are a shimmery spectacle because of hundreds of little glowworms spinning traps for cave-dwelling insects. But to human visitors, the silky strands look like an alien sky.
2. Cueva de los Cristales, Mexico
This insane crystal cave is off-limits to anyone, but the luckiest researchers because of extreme temperatures and humidity. If you can swing a way in, you’ll see piles of crystals up to 36-feet long.
3. Reed Flute Cave, China
The natural beauty of the Guangxi Provence Cave is elevated by the addition of bright neon lights. It’s truly magical to see the rock formations illuminated with such bright colors, especially when the cave lacks natural light.
4. Hang Son Doong, Vietnam
Hang Son Doong is the world’s largest cave passage. It’s two and a half miles long, 300 feet wide and 600 feet tall. Even better for the get-there-first crowd, the Vietnamese cave has only recently opened to visitors since professional cave explorers only discovered the spot in 2009.
5. Caverns of Sonora, Texas, U.S.
In Texas’s Sonora Caverns, the walls glow pink. The seemingly endless corridors are a rose-colored landscape of stalagmites and stalactites (but don’t worry, you don’t have to remember which is which from those grade-school lessons).
6. Cenote Dos Ojos, Mexico
Snorklers love this underwater sinkhole in the Yucatan region of Mexico, but you can also simply float in the shockingly clear water. Dos Ojos is one of the biggest underwater caves in the world, so keep both eyes open to take in the vast expanses of turquoise water.
7. Mammoth Cave, Kentucky, U.S.
The longest cave system in the world is hidden beneath rural Kentucky. There are 400 miles of caverns that have been explored, but since the caves are so massive, no one really knows how much is left to discover.
8. Catedral de Marmol, Chile
The Marble Cathedral in Patagonia is home to 5,000 tons of marble. The caves are located on a glacier-fed lake and the clear blue water reflects off the marble, giving both surfaces an icy blue hue.
9. Fingal’s Cave, Scotland
This Scottish cave was known as the “Cave of Melody” in the days of the Celts and even now, the sound of the waves echoing through the cavern is one of the coolest parts of Fingal.
