The Black Labyrinth tour ($150, three hours) involves floating in a wetsuit on an inner tube down a river through Ruakuri Cave. The highlight is leaping off a small waterfall and then floating through a long, glowworm-covered passage. The trip ends with showers, soup and bagels in the cafe. There's also the more adventurous Black Abyss tour ($260, five hours).
The latter includes a 35m abseil into Ruakuri Cave, a zip line and more glowworms and tubing.
Minimum ages apply for all tours, and there are occasional discounts if you prebook online. Check the website for combo deals also incorporating entry to the other Waitomo caves.
