Waitomo is around 190 km from Auckland situated on the north island of New Zealand. I had book the time slot to view some part of the places at their website with a fee. It is know as the best glow worm caves in New Zealand. Parking and dinning are easy to find and plenty at site. I book the triple cave combo that is Waitomo Glowworm Caves, Aranui Cave and Ruakuri Cave at their website for around 100+ NZD. So plan ahead your timing, it need time to travel from 1 site to another. There are guides to show you around at places. The boat trip to the Waitomo Glowworm caves is a WOW. There are also several tour companies organised tour trip to here from Auckland.
