Reed Flute Caves, China
This 240-meter-long cave system has been one of Guilin, China’s most popular attractions for over 1200 years. The beautiful stalactites, stalagmites and pillars were all created through water erosion. In the present day, they are highlighted by multi colored lights which create a truly surreal environment.
Sadly, the mining company that owns the caves could no longer afford to keep the massive pumps going to clear the chamber. I believe the pumps were shut down a few years ago and the cavern is refilled with water. The crystals are growing once again, but no one will ever see it.
