The scenery of Guangxi extends even below the region's resplendent surface, its steep karst geology concealing a magical world underground. Though nature carved it, Reed Flute Cave's splendor has been lightly assisted by humans: First artificially lit in the post-World War II era, today it's wired up with a rainbow of electric lights that illumine the cave's natural mirror pond, accenting an already fantastical aura. The cave's name comes not from its flute-like stalactites and stalagmites (and even columns like the one in this shot) but from the bamboo-like reeds that grow just outside of it, long used to make traditional xiao flutes.
