Located about 2 hours by road south of Auckland. We walked into a dark cave by steps and onto a boat ride. Everyone is asked to be quiet, apparently these glow worms are sensitive to sound. They are insect larvaes hanging from the ceiling of damp dark cave with a glow to attract and catch insects coming into the river inside the cave.
The boat ride took us to different parts of the caves and the glowworms are like shining stars of a universe above. Worth a visit to this natural wonder. Apparently there are places in New Zealand with glow worms but Waitomo is the largest, most accessible and most famous.
There is a sign to mind your head at the entrance - unfortunately I did not on my way out.
For more than 100 years the Glowworm Cave of Waitomo has attracted millions of people from all over the world. A guided tour of the limestone cave and a boat ride through the darkness of the Glowworm Grotto where numerous insects glow reflecting off the water deep under the ground is a trip not to be missed.
