On entering the Waitomo Caves we walked all through the caves which were quite pleasant and the usual rock formations which are very beautiful with the atmosphere of cool dampness with earthy smells.
From my point of view the exciting part came when we got to see the glow worms. We saw a few on the cave roof as we were walking through but then we got into a boat and we were pulled silently through the cave looking at thousands of these little glowing creatures. The whole roof was covered in wonderful bright patches which reflected in the water too. The boat was pulled along buy high ropes which we could just see but it made it completely silent and enabled you to enjoy the spectacle in relative quiet. It was like floating in space as it was dark, pretty well silent and the glowing worms were like stars in the night. It was an almost magical experience, like nothing I have ever seen before in nature.
