10 of the World’s Most Breathtaking Caves (4 of 6)

6. Reed Flute Cave, China

The Reed Flute Cave has basically been a tourist sight long before tourism was even a thing. For more than 1,200 years, visitors have come to marvel at the calcium columns. The cave gets its name due to the abundance of reeds that grow along its mouth, which is used to make the musical instrument. 

7. Naica Mine, Mexico

If you’re a crystalphile (and who among us isn’t?) Naica Mine is like a dream come true as it contains some of the world’s biggest crystals. However, if you’re hoping to actually see them up close, we’re sorry to break the news: due to the depth and heat, it is actually closed to the public. You can still enjoy photos of it though.
