In the Maori language, wai (water) and tomo (hole or shaft) name the small village of Waitomo on the North Island of New Zealand. It has extensive underground cave systems famous for glow-worms that light up the caves. The tour operator in Waitomo, Black Water Rafting, has a variety of tour levels for the cave systems. I was privileged to discover and join the Blackwater River Rafting tour called the Black Abyss, the most extensive tour option (5hrs) they have featuring abseiling down a 35 meter hole, zip lining in the dark, rafting with inner tubes in the cave river, and finally climbing up water fall to get out of the cave. This was quite the magical, exciting and surreal experience. You just can’t believe you’re there doing these things.
