The other good news, was that after all the rain, the river was flowing at a good level, the best all this winter, so promised some god honest white water action. And it delivered.
Below is the photo of the waterfalls, which is where we launced in from, at the base of the Mountain Valley Adventure Lodge and set off for a 4 hour amble down the river.

The main purpose of today was to get used to running some grade 2 rapids, and to learn how to read the river and pick the best line to run rapids. We also managed some sight seeing and found the highest rail viaduct in Austrailasia standing at 95meters.
Things got a bit more interesting after the 30minutes of warming up, and we started to learn about holes, buffer cliffs (nasty), upstream V's (bad), downstream V's (good), wave trains, undercuts (very bad) and my favourites: splash walls (killers). Wave trains are without a doubt the most fun, and a bumpy ride down a wave train is bound to get the heart racing for the first time. Of course we were here to learn how to maximise our downriver speed, and not have fun (although we were ordered to smile), so the guide was telling us that the best line was to go down just on the outside (or inside) of the train and try to avoid the big lumpy stuff. Easier said than done.
When it came to downstream V's, we were supposed to think of them as X's and enter the V on the left, and cross over at the intersection, and head out the right (opposite) side. Again, easier said than done.

Above we have a photo of the Mohaka, on fairly low flow, and you can see how the cliffs just slice into the river, and potentially imagine being pushed into the side of the cliff and having water come over the top of you. That would be a bluff (bad), and although not good you can actually learn INTO the cliff and push off with your hands (or paddle) and shimmy you way down. Thankfully I avoided this, but it took a bit of getting used to paddling within a meter or two of immanent danger, but realising that you were OK to do so.
In fact that seemed and recurring theme in all of kayaking, that the correct line was only a knife edge away from immanent danger.
This next photos was of one of the gnarliest rapids. Again, the flow was quite a bit higher than this (borrowed) photo. You can see a rapid (about 1/2 way through the photo) which requires approaching from "river right" then crossing the intersection (the "X") and coming out on "river left", then we have a 20m gap till we again need to be on "river left" and come around the bend, but remembering to put the power on, so that that we can take a sharp right, and "eddy out" on "river right" (which is actually the stony bank on the bottom left of this photo).
Which reminds me of some terminology - "River right" means, the right hand side if you were going DOWNstream (usually you are). Even if you were going backwards, River Right does not change.

So, I actually had a great day, and managed to stay upright (not dry tho) all day and really enjoyed my first grade 2 run.
Here is the map of the route we took, some 11km.
