Waitomo Caves winds a limestone passage carved by an underground stream, its ceiling scattered with the glow of New Zealand's native bioluminescent glowworms. Orbit the passage, toggle the glowworm glow, and see the river channel below.
Published figures: discovered 1887 by local Maori chief Tane Tinorau and English surveyor Fred Mace, opened to the public in 1889; carved in limestone laid down under an ancient sea roughly 30 million years ago; home to Arachnocampa luminosa, the glowworm found only in New Zealand; the Waitomo Stream flows through the cave and carries visitors by boat through the dark Glowworm Grotto.

Waitomo Caves 3D Explorer
This browser explorer shows the Waitomo Glowworm Cave as a winding limestone passage carved by an underground stream, its ceiling scattered with small points of bioluminescent glow - a cave archetype distinct from the layer-stack of Mammoth Cave and the open doline-lit passage of Son Doong Cave already shown on the other cave explorers.
Waitomo Caves sits near Otorohanga in the Waikato region of New Zealand's North Island. It was explored in 1887 by local Maori chief Tane Tinorau, guided by English surveyor Fred Mace, who rafted along the underground Waitomo Stream and found a ceiling glittering with tiny lights. The cave was carved through limestone laid down under an ancient sea roughly 30 million years ago, later uplifted and eroded by the stream that still flows through it today. The lights come from Arachnocampa luminosa, a glowworm species found only in New Zealand: the larvae glow to lure flying insects into sticky silk threads they dangle from the ceiling. Tane Tinorau and his wife Huti opened the cave to visitors in 1889, and their descendants still co-manage tours of the Glowworm Grotto by boat today.

Frequently Asked Questions
Who discovered Waitomo Caves?
Local Maori chief Tane Tinorau and English surveyor Fred Mace explored it by raft in 1887, following the underground Waitomo Stream.
What makes the glowworms glow?
A chemical reaction in the tail of the Arachnocampa luminosa larva, a glowworm species found only in New Zealand, produces a soft blue-green light that lures flying insects into sticky silk threads.
When did Waitomo Caves open to visitors?
1889, two years after its 1887 exploration. Tane Tinorau's descendants still co-manage tours of the Glowworm Grotto today.
What rock is the cave carved from?
Limestone laid down under an ancient sea roughly 30 million years ago, later uplifted and eroded by the Waitomo Stream that still flows through it.
Where is Waitomo Caves?
Near Otorohanga, in the Waikato region of New Zealand's North Island.
How do visitors see the glowworms?
By gliding through the dark Glowworm Grotto in a small boat along the Waitomo Stream, looking up at the glowing ceiling.
Is this a geological simulation?
No. It is an educational explorer using published discovery and geology figures - the passage shape, glowworm density, and lighting are procedural teaching cues.
