Waitomo: where the blue light in the caves comes from

In the dark caves of New Zealand's Waitomo region, you can see many small bluish lights. They are created by the larvae of luminous insects; familiarity with this phenomenon helps to see the cave as a living environment, and not just an unusual decoration.

Who creates light

The New Zealand firefly Arachnocampa luminosa is a fungus gnat. Its larvae glow; They live in moist, sheltered areas and use light to hunt small prey.

Why silence is important

Cave environments are sensitive to change. Lighting, noise and touch can interfere with observation and harm occupants. Filming rules vary between caves and operators, so please check them before entering.

How to plan a visit

Choose a route that suits the duration and level of physical activity: walking and more active cave tours vary. Check age and health restrictions, clothing recommendations and cancellation conditions. Follow the guide's instructions and do not touch the walls or the threads of the larvae.
