The Mirror Cave, Batu Cermin (Goa Batu Cermin), is a limestone stalactite cave minutes from Labuan Bajo on Flores. The name means "stone mirror": at certain hours sunlight enters through openings in the roof and reflects off the wet walls and stalactites, creating mirror-like flashes. The cave walls hold imprints of coral and marine creatures — proof that this place was underwater millions of years ago.
