The Glowworm Caves
The Waitomo Caves are a limestone cave system approximately 200 kilometres south of Auckland (about 2.5 hours by road) famous for the glowworm (Arachnocampa luminosa) — a bioluminescent insect larva found only in New Zealand that creates pinpoints of blue-green light on cave ceilings, producing the effect of an underground starfield. The signature experience is a boat tour on the underground river, gliding in silence through the Glowworm Grotto where thousands of glowworms illuminate the cave ceiling above.
Black water rafting (tubing through underground rivers in wetsuits, floating beneath glowworm-lit ceilings) and abseiling into cave chambers provide the adventure alternatives to the gentle boat tour.

What are glowworms?
Arachnocampa luminosa — the larvae of a gnat species endemic to New Zealand. They produce bioluminescent light to attract prey into sticky threads hanging from the cave ceiling. The effect — thousands of tiny blue-green lights in the darkness — resembles a starfield.
