China’s Reed Flute Cave is also known as the ‘Palace of the Natural Arts’, and that should tell you plenty about what to expect. Named after the reeds that grow outside (which are used to make flutes, obviously), the Reed Flute Cave’s walls are peppered with inscriptions from centuries gone by – proof if proof were needed that people have been paying attention to this place for a long old time. The interior of the cave is also lit up by multicoloured lights, giving it a real otherworldly theme that adds weight to the nickname.
