Legendary Black Water Rafting Co. Black Abyss


New Zealand’s maximum-adrenaline Black Water Rafting tour

Allow 5-hour's for this adventure; you’ll abseil to the depths of the earth, zip line through a glow worm studded cave, climb underground waterfalls and tube through fast-flowing waters.

After checking in you’ll meet your expert guides, who will help you gear up and teach you the basic abseiling and tubing skills you’ll need in the cave. It’s then time to abseil 35 metres into the depths of Ruakuri Cave. The fun doesn’t stop there though, next your guide will connect you to a zip line and you’ll fly through the pitch-black cave, beneath a sky of glow worms. After a quick snack, it’s time to collect your tube and jump into the water, where you’ll float below a living sky and raft underground rapids. Your guides will then send your tubes to the top of the cave and you’ll be free to climb over rocks and up waterfalls, and float through fast-flowing waters using the buoyancy of your wetsuit. You really will test your limits on this unforgettable journey.

Once your tour finishes, warm up with a long-awaited hot shower and head back to the Waitomo Homestead.
