The surreal looking caves of New Zealand?s north island get their amazing appearance from thousands of tiny glow worms that line the caves walls and ceilings. New Zealand has long been known as a place of outstanding natural beauty but this cave system is certainly one of the more memorable naturally occurring phenomenon?s.
The light that the glow worms give off makes the cave look like a beautiful starry nights sky. The caves were opened to tourists in 1889 after being discovered in 1887 and nicknamed ?Glowworm Grotto?. If you think these pictures are impressive then imagine seeing the caves in person.
