Under the green hills of Waitomo lies a labyrinth of caves, sinkholes and underground rivers.

The caves were carved by underground streams pushing through soft limestone over thousands of years. Many have amazing stalactites growing down from the ceiling and stalagmites growing up from the cave floor, pointy cones of layered rock formed over centuries by dripping water. The cave walls are also decorated with galaxies of native glow worms.

The easiest way to see the caves is with a walking or boat tour. If you’re into adventure, try the unique experience of blackwater rafting – you’ll crawl, swim and float through the caves on a rubber tube. Or you could abseil or zip-line through the darkness. However you choose to explore Waitomo Caves, you’re bound to agree they’re a wonder of nature.
