The Waitomo Glowworm Caves attraction is a cave at Waitomo on the North Island of New Zealand, known for its population of glowworms, Arachnocampa luminosa. This species is found exclusively in New Zealand. They are around the size of an average mosquito. This cave is part of the Waitomo Caves system that includes the Ruakuri Cave and the Aranui Cave. The attraction has a modern visitor centre at the entrance, largely designed in wood. There are organized tours that include a boat ride under the glowworms. The most renowned animal in the cave is the glowworm Arachnocampa luminosa. There are several small underwater lakes that were created by freshwater creeks or brooks.

The walls of the caves are covered with a variety of fungi including the cave flower (a distant relation to the genus Pleurotus) that is actually a mushroom-like fungus. The most common animals in the caves are insects. This includes albino cave ants, giant crickets, and of course the glowworms.
