The Glowworm Caves of New Zealand

The Glowworm Caves of New Zealand

Breathtaking and beautiful, Waitomo caves are not like any other caves across the world. What makes them unique is that they glow! In pitch darkness, rowing over the shallow waters, when you look up, it appears as if the stars have homed on the ceiling of the caves. What makes it possible is among the rarest of creatures in world- the mosquito-sized glow worm Arachnocampa luminosa, hence the name glowworm caves.


There are around 300 limestone caves in Waitomo region that have been created over the last 30 million years by immense geological and volcanic activity. These Glowworm Caves were formed when the place was still under the ocean. The limestone that is composed in the cave walls is composed of corals, seashells, fish skeletons and other marine animals fossilized for over millions of years, layered upon each other and compressed into limestone, making it 200 meters thick. The caves have been formed by the dripping water from the ceiling along with the formations by the running water, making unique limestone formations.

These glow worms are closely studied by Scientific Groups and they monitor the air quality, humidity and air temperatures of the caves so as to provide the most suitable conditions for the worms to grow. This determines how many people should enter the cave at one time and when the flow of air should be changed.


The Waitomo Glowworm caves were found by local Maori Chief Tane Tinorau who was accompanied by Fred Mace, an English surveyor. Building their own rafts with candles in hand, the two set out to explore deep within the caves that were known to exist by locals. When they entered the Glowworm Grotto, they were surprised to see the ceiling glowing blow unceasingly. As they went deeper they discovered the limestone formations. The place has been a tourist hotspot since the then discovery in1887.
