Caves And Volcanoes

Waitomo - home to glow worm caves and possibly Hobbits

I’ll cut to the chase here: we visited two caves in Waitomo where we saw glow worms. If you don’t know what they are, then the name is a bit of a give-away. But they’re actually larvae that cling to the cave ceilings, and are bio-luminescent so as to attract prey. It’s only their livers that are glowing though, but in the pitch black of a cave, it makes no difference. As we cruised up and down a cave river in total darkness, we may as well have been looking at a constellation of stars overhead. It was quite otherworldly.
