I hopped off my bus at a small village called Waitomo to see the glowworm caves, which I had heard were really good. One of the activities I really wanted to do was a night abseil through the caves, which meant I had to stay overnight (for 2 nights because there was no bus the next day). When I arrived, I found there was nothing in the village - my hostel, a couple of caving companies and (most importantly) a pub, so I was a bit worried it was going to be a boring couple of days. However, the scenery was amazing and the weather was good - also in the evenings I bumped into seven different people I had met at various places around Australia! It was crazy seeing so many people I knew in the middle of nowhere!
The night abseil was really cool - it was a 50 metre abseil and I did it twice, once at dusk and once in the dark to see the glowworms. It was fantastic - looking up at the canyon walls it was like looking up at the stars. Unfortunately the photos of the glowworms didn't come out very well, so I haven't put them on here. I also went into the Ruakuri caves, where we saw some amazing stalactites and stalacmites and the glowworms up close. They hang threads (like spider's webs) down from the ceiling of the caves and use their lights to attract flying insects, which then get trapped in the webs and eaten - really cool!
