Ngarua Caves

Our flight from Nelson didn’t leave until the afternoon, so we stopped on our drive back to tour the Ngarua Caves. We arrived a little after 10 and discovered that there would be a tour at 10:30, so we joined that, along with around 12 other people.

We donned hard hats and met our guide, Rachel, at the mouth of the cave. I enquired about cave wētā   but it appears they don’t have any. We were enjoined not to touch any of the stalactites or stalagmites as contamination from oils on your fingers will slow down growth…which is a leisurely 25mm every 80 years. Strange units, you might think? Well, it probably started out as one inch every 80 years.

We walked through with Rachel taking up the rear to ensure no-one got left behind, and stopped at the Stop signs where she gave us a bit of information about each place, including how they were discovered in the first place: apparently an apprentice surveyor dropped a tool whilst out doing some surveying, and it fell down a hole. “Well, go and get it” said his supervisor….and presto! Caves discovered! The caves are in a rock formation caused by the collision of two plates, and are about 450 million years old. These days, electricity, boardwalks and handrails have been installed to ease our passage and we are able to explore more. Some of them had columns where stalactites and stalagmites had fused. There was also a complete skeleton of a moa that had fallen through a pothole and died down there - several such skeletons have been discovered. We ended up in a large cave unsurprisingly called The Cathedral, which was the end of the system as far as we were concerned. We then ascended a set of Death Stairs to reach the outside and emerge, blinking, into the sunlight.

We drove on from there and stopped at McCashin’s Brewery for some lunch. Last time we were there I acquired some feijoa liqueur from the bottle shop and intended to do the same this time, only to find that Nelson Council had rescinded their licence and they were unable to sell me any. Poo.

That was about the end of our travels. We dropped the somewhat muddy car off at the rental place and waited for our flight to Wellington.
