White water rafting on Kaitunga River

So despite the rain on the morning, we went white water rafting on the Kaitunga River. We got picked up at our caravan park and taken to the office where we got given gear and safety instructions before hitting the water. I volunteered us to sit at the front of the raft and Colin looked at me with trepidation, but before he could object the guide was giving us some extra instructions / warnings, which made me doubt my enthusiasm and got Colin more worried.
We got onto the river and it was all going well with the river still smooth and us kind of going along very calmly. Then we spotted the first rapid and the big drop we would have to make, only to hear this was a small one.
After this first rapid we were soaked, though the others on the boat were mostly dry and we'd swallowed a lot of water through our mouths and eyes. At this point Colin had an "I told you so" look on his face, which I ignored.
When we got through the other side of the rapid we were pushed into a big pool where we all got out of the raft and swam. The water was surprisingly not cold and having the swim actually warmed us up.
Then we got back in the raft and continued down the river all waiting for the big fall of 7 metres, which we were told is the biggest rapid in the world that non professionals are allowed to raft over on tours like this.
When we finally got to it we went through a few safety tips again and prepared ourselves for it. So we went for it and one moment we were paddling towards the edge and next our guide shouted for us to all get down in the raft and hold on for dear life. The next few seconds kind of go by really quickly although you're also aware of every second and you're not quite sure what's happening to you. Our whole raft went under the water and stayed there for quite a long time (our guide said afterwards that he hadn't ever been under for that long with a group before) and it was on the left edge for most of this time, but it didn't flip over and when we eventually came back up both Colin and I and only 1 other person were still clinging on and managed to stay in the raft. Everyone else fell out, including our guide. We hadn't even realised that our guide had fallen out, because he got back in so quickly, I guess to make sure everyone else was okay, and high-fived the 3 of us for not falling out. It was only when we saw the photos that we realised he fell out too... and he tried to trick us into thinking he hadn't!
The rest of the journey was very mild in comparison and we got a chance to enjoy our surroundings while only rowing every so often.
It was so much fun we wanted to do it again.
