Reed Flute Cave

America has plenty of gorgeous cave systems. There's the Mammoth Cave National Park in Kentucky, the Carlsbad Caverns National Park in New Mexico, and the Moaning Cavern in California, just to name a few. But while those caves are all pretty good looking, the Reed Flute Cave in Gulin, China just might be one of the most beautiful of them all. The Reed Flute Cave, which received its name from the massive amounts of verdant reeds that grow at the entrance to the cave, reeds that are commonly used to create flutes, is a is a natural cave system that was slowly carved out of the karst limestone mountains over the course of millions of years, creating an incredible sight that has been one of the most popular local attractions for well over a millenia, but was only rediscovered in the 1940s.  From Wikipedia:  Inside, there are more than 70 inscriptions written in ink, which can be dated back as far as 792 AD in the Tang Dynasty. These aged inscriptions tell us that it has been an attraction in Guilin since ancient times.
