After debating between the Black Abyss (5 hour) and Black Labyrinth (3 hour) tours, I decided to book the Black Abyss tour because it had abseiling/rappelling and flying fox/zipline. If I were to do it again, I would save the money (~NZD$100/person) and book the shorter tour. You rappel in to the cave to start the tour then do a short zipline, and that's the end of the rappelling and ziplining, which I was a little disappointed by. Overall, I did enjoy the tour. Floating in the water with all the glowworms above you was a very cool experience. We got a couple snacks and warm drinks on the tour, which was unexpected and a nice addition.

There were two other couples on our tour with us, one of which was Chinese and didn't speak English fluently, but seemed to understand a decent amount. Our guide was nice to us, but very rude to the Chinese couple. It does seem frustrating and potentially dangerous as a guide to not be able to communicate well while in a cave, but it was still kind of off-putting.
