Reed Flute Cave, Guilin, Guangxi, China

The cave got its name from the verdant reeds growing outside it, with which people make flutes. Inside this water-eroded cave is a spectacular world of various stalactites, stone pillars and rock formations created by carbonate deposition. Illuminated by colored lighting, the fantastic spectacle is found in many variations along this 240-meter-long cave. (Source)
