With our last day of skiing behind us, we said a final farewell to the New Zealand snow and the stunning Mt. Ruapehu. Now, the journey was northwards towards Auckland, our final destination. There we would say goodbye to our trusty Maisie Penny and board our flight to Santiago for our South American and ultimate leg of the journey.
First however, we had one little stop to make, in a very little town (home to about 40 people) to see something very little, but very amazing – The Waitomo cave glow worms.
The caves we visited, were strictly speaking outside the Waitomo area. We chose them as the company operating the tours brings fewer people, thus fewer lights, and therefore a much more impressive glow worm experience. So impressive in fact, that Sir David Attenborough and his team used it for their Planet Earth and Life un the underground series for BBC. Now there is a man whose opinion I trust on the quality of experience in the natural world!!!
After a chilled out evening, watching a top quality NZ movie, The Whale Rider (if you haven’t seen it – watch it- I still loved it 4th or 5th time round) and a good night’s sleep, we rose and headed to the Spellbound Tower – out meeting point.
The tour, lead by a local guide, a proud kiwi, by the name of O’Halloran, with buckets of Irish and Scottish ancestors (we really do get everywhere!), began with the first of two caves. This was a dry cave. Many years ago, there was water flowing through, which carved out the cave itself, but today, the
river flows elsewhere, having found itself a more suitable path, leaving behind a stunning array of chambers with stalactites and stalagmites and even numerous animal bones, from goats, cows, possums and even the bones of an ancient (and now extinct) Moa – an indigenous bird to these parts, which was hunted to extinction by Polynesian settlers many thousands of years ago.
The cave, conveniently lit up for punters like us, was stunning. And when our guide dimmed the lights for a moment, we got some impression of just how dark the next cave would be. After a leisurely stroll and a welcome hot cuppa with an oat biscuit (the cave is pretty chilly varying between 4 and 12 degrees), we headed for the highlight of the tour, the glowworm cave.
Just prior to the cave, we stopped for an Australia Zoo style show. Our guide introduced us to one of the river’s local residents, a long finned eel –native to New Zealand. Coaxing her slowly to the surface with some tasty goat meat, we were lucky enough to see her pop her head right out of the water, and ultimately she kindly obliged by turning a full circle and showing us her full length, over 2 feet of it!
There was no swaying us from the object of our visit though. The glow worms were waiting. We were kitted out in had hats and looking like a troop of miners, we marched in. Before we walked into the real depth of the cave, our guide pointed out the various stages in the life of the glow worm around the cave walls. The eggs, laid by the female, which incubate for 10 days, before hatching into larvae. It is the larvae who produce this phosphorescence, caused by an enzyme reaction with an oxidised fat, as we were told. The larvae (the glow worm), spin some 70-80 silky threads each, which drop from the cave wall, and catch the unsuspecting little insects who are attracted to its glow. And the larvae feed! Ultimately, they spin themselves a little pupa, where they reside for about 30 days, before emerging as a mouthless gnat. This poor little fellow/lady, cannot feed. It’s sole purpose now is to mate and/or lay eggs. Once this task is complete, it will eventually die of starvation, or get caught in the sticky threads of some hungry relation. Its a tough life.
After the entomology lesson, we walked deeper into the cave, periodically switching the lights off to see the few twinkling lights above us. Our guide assured us, that after a little time in the cave, we would see many more. We boarded a little boat and slowly drifted down the river. It was pitch black, we could see nothing save for the odd little glow above. Gradually however, as our eyes became accustomed to the dark, the white mining hats became visible, then slowly the silhouettes of the other passengers. By this stage, the sight above and around us was nothing short of awesome. I know I promised never to use that word again, but no other superlative will suffice. It was like staring up into the night sky, but not like any night sky I have ever seen, being the city slicker I am. It was how I imagine the night sky must look, in the middle of the dessert, hundreds of miles from anywhere, with no faint orange glow polluting the light, and not a cloud in sight.
It is difficult to describe just how many glowworms were busy over head, living their short, but hectic little lives. As we were unable to photograph in this cave both because we lack the necessary fancy equipment, but also because unwanted flashes will actually cause the larvae to dim their glow, which take many hours to recover, they’re a little photo-sensitive! However, we have been promised some pictures on e-mail, so hopefully once we are home, we can show you just how amazing it really was.
