New Zealand Cruise 2026

Glowworms near the Bay of Islands

There were several tours to some glowworm caves in New Zealand, but this one seemed the easiest to get to. Unfortunately, photography inside the caves was not allowed, so the only photo I got was the tour group assembling for the short walk into the cave. Once the lights were turned off, you could see the tiny spots of light spread across the upper cave ceiling, only 20 to 30 feet away. I expected that the spots would be like fireflies, but they were much smaller, probably only 1 mm diameter, and pretty bright blue. In the first cave, they were spread out just like the Milky Way in the night sky. It was hard to hold your head so far backward for any long time, but the sight was pretty impressive. We were in the cave for about 30 minutes.
