Note - the Cuvier Valley has no clear track (just a marker every kilometer, or so, which is almost useless). The route from the Narcissus end over Byron Gap is well marked which is just as well because the pad would otherwise be quite difficult to follow, but the section over the plains south of the lake to the Cuvier River is impossible to find much of the way, so you have to battle your way through the button grass, and occasional (thankfully thin and low) tea tree bands.
NB: This walk is not recommended for the inexperienced.
Byron Gap! When I reached the top, and started descending through the Pandanii forest, I got to understand the expression, "my heart soared". It was just so beautiful, It's the best example of a Pandanii forest I've seen anywhere (better than the one half way up the side of Mt Oakleigh, and better than the one around the corner of the forest near Pine Forest Moor). And the rainforest, and creeks were just astounding.
But you're all just going to have to take my word for it, because I don't have any photos of any of it. My batteries went flat (yet again) as I stood up on the huge cut-down tree trunk above the new Windy Ridge Hut to take shots of the snow covered Acropolis/Geryon/Massif/Falling panorama. Bummer. Strange thing though. I was talking to somebody else at Windy Ridge who stood on the same tree trunk for photos, and the clouds instantly swooped in and covered the mountains. Then at Narcissus, somebody else was telling me that he stood on that tree trunk and his lens fogged up beyond all use. I think it's bad karma for cutting down that tree to make way for the hut!

So the only photos I got were on the way in (of Mt Gould & Acropolis).
I spent my first night of this trip at Echo Point for the first time after walking in late after work on Wednesday. Great spot. Nice little hut. Noisy possums trying to break the door down and rolling square things down the roof, I'm sure, and I think I heard a rat on the bed next to me once. Thankfully they all shut up after a couple of hours. Thank the PWS for the food locker in that hut.
On this trip, I saw a wedge tail eagle, patted two echidnas, saw about 20 wallabies, and an incredibly noisy flock of about 100 currawongs. I also trod 5cm from a piece of bark that I thought looked remarkably like a snake, and then it slithered into the coral fern, and I realised there were no trees anywhere nearby.
My knees are very scratched and very sunburnt. A somewhat uncomfortable sensation. But well worth it.
