Summary

The Waitomo Caves are limestone caves on New Zealand’s North Island. Underground chambers and passages include habitats of glowworms, whose light transforms the appearance of the dark subterranean spaces.

The combination of geology and living light is distinctive. Mineral forms establish the scale of the cave, while tiny points of illumination turn biological detail into the most memorable part of the scene.

The story of a place

A subterranean world of limestone and living light

Waitomo brings together two very different attractions: limestone cave forms and the delicate light of glowworms. A dark boat passage beneath points of light can feel otherworldly, but the living organisms and cave environment deserve as much attention as the spectacle.

Choose the cave experience carefully. A guided walk, a boat tour and an adventure-caving excursion have different access requirements and reveal different features. Photography rules also vary, and a good visit may involve putting the camera away altogether.
