You’ve heard of white water rafting, but what about black water rafting? This uniquely New Zealand experience is a must-do for anyone who loves an off-the-beaten-path adventure. I’d argue it’s the best way to explore the beautiful Waitomo Glow Worm Caves! Here’s everything you need to know before adding this incredible activity to your New Zealand itinerary or bucket list.

What is black water rafting, exactly?
Just as white water rafting describes a fast-flowing river and rapids, this black water rafting adventure will have you navigating the dark (i.e. black) rushing rivers that flow through the depths of the caves. The water is sparkling clean though — only “black” because you’re down there with nothing but a head torch.
One notable difference to clarify, is that black water rafting doesn’t actually involve any rafts lol. But you do get an inflatable tube that you’ll use to float down some of the caves’ glow worm-covered chambers. It’s a fast-paced activity, and you’ll do a bit of climbing, jumping, swimming, and even abseiling if you book the 5-hour excursion.

When to go black water rafting
The caves are open year-round and the water is going to be just as cold no matter when you go. So technically, there’s no bad time of year to go on this adventure in Waitomo.
That said, the trip can sometimes be cancelled if there’s been a lot of rain, and New Zealand winters (from May to August) can be very wet. Cancellation is pretty rare, but an important safety precaution.
It’s also pretty miserable to come out of the chilly cave in a soaked wet suit to crisp cold air, but they do provide you with hot soup and hot chocolate after the trip no matter what time of year you go!
If you can time your visit in the summer, definitely do that. I went in October (kinda shoulder season) and it was perfectly fine, but I was still super cold walking back to the change rooms.
How to book the experience & total cost
You can book online through the Discover Waitomo website, Get Your Guide, or hope to find a good discount on BookMe. (More likely in the off-season, but always worth a try.)
There are two different black water rafting tours to choose from and both are operated by the same company — Legendary Black Water Rafting Co. Make sure you book the one you want!
Black Labyrinth: 3 hour excursion, $188. This is the one to pick if you’re not totally sure how much you’ll like the experience but want to give it a try. It’s also the more budget-friendly option, and still epic.
Black Abyss: 5 hour excursion, $314. This is for the hardcore explorers. It includes some abseiling and a zipline that the Labyrinth tour doesn’t have, so while it’s significantly more expensive, it’s a lot of bang for your buck! I did the Labyrinth but wish I’d just spent more to do this one. (There’s always next time!)
What you need to enjoy the experience
If you’re not yet convinced about whether black water rafting in Waitomo is for you, here are some important considerations:
- A reasonable level of fitness. For reference, I am not “fit” and I was fine.
- Confidence in your ability to swim, though you’ll always have your tube.
- To be over the age of 12 (even if accompanied by an adult).
- To weigh at least 45 kilos/100 pounds.
- To be comfortable in a cave. If you’re claustrophobic, this probably isn’t for you. Same for if you’re afraid of worms that glow. And I won’t lie to you, there are eels in the water, but they mind their own business.

Things to bring black water rafting
- A swimsuit. Something comfortable for under your wet suit.
- A towel to dry off after the experience. They also have showers if you want to bring soap and shampoo etc.
- Your booking details. It’s becoming a popular activity, so it’s very unlikely they’ll be able to slot you in even if it’s a weekday. Book in advance!
- A sense of humour and a good attitude. The guides are super outgoing, make lots of jokes, and are there to have a good time. You’ll want to match that energy. And on that note, you’ll want to bring…
- A LOT of energy. The whole thing is very go-go-go, so arrive ready for a full-on day!
Things NOT to bring black water rafting
- They don’t let you film in the cave (not even a GoPro or digital camera). It’s dark in there anyway and it would be hard to get anything that looks good. So leave your stuff in your car or the locker they provide. The guides do take photos for you along the way, which you can pay for later. (And while it’s annoying to have to pay for that, I think it’s worth it for the ‘gram.)
- They provide: All the equipment including a helmet, wet suit, water socks/boots, and a head torch. So you’ll be kitted out and don’t have to worry about a thing!

All the photos are pretty mid, but black water rafting is more about the experience!
