Glow Worms
Bacteria isn’t the most fascinating thing you can find, but this isn’t the case for this cave in New Zealand. Rather, they’re a cause for celebration, especially when you see the depths of the walls and ceilings being consumed by phosphorescent worms – otherwise known as glow worms by locals. You’ll be fascinated by how these bacterias light up the dark walls each night, which is why it’s such a popular tourist destination. You can even go for a kayaking tour while being amazed by them through the caverns.
