tour times was very frustrating but the tours themselves were good. The Ruakuri cave was amazing. We had an excellent guide and at one stage she turned out all the lights and we could see and hear people black water tubing in the river below us.
The glowworm cave was really good too, although there were too many people on the tour for comfort and our guide was a bit unfriendly at times. Apart from that, the short boat ride to see the glowworms was amazing and a great experience.
