We did K2K finishing yesterday.
My thoughts:
Kanangra Walls - Cloudmaker: much the same as pre-fires, a few sections where there is more vegetation along the sides of the track, but the track is clear until you get within about 100m of the Cloudmaker summit when it suddenly seems to vanish. If you hadn't been to Cloudmaker before then you should take care to get to the summit (assuming you want to get there).
Cloudmaker - Dex Creek: we didn't pick up much of a track until we were on the northern spur heading to Dex Creek, once on the spur we followed a track on and off
Dex Creek - Coxs River: clear track up onto Karrung Top. Then overgrown and slow through to the northern side of the 953 high point (1km/hour or less). 953 to Mt Moorilla Maroo is ok. Mt Moorilla Maroo to the next knoll where the ridge turns north is slow and overgrown. Sometime after we'd turned north we found a pad and followed it through to the eastern slopes of Mt Strongleg - the pad is through 3-4m high vegetation much of the time, so it's not easy walking, but is a lot easier than no pad! There's some open spots around Mt Amarina to have a break. There is still a pad around the eastern side of Mt Strongleg - you may need to hunt around for it. Strongleg Ridge wasn't as overgrown as the main ridge - much of the Hardenbergia seems to have died off, or has been flattened on the pad. We lost the pad only 80m vertical metres from the bottom and found ourselves caught up in passionfruit vine, but that was the only bad vine entanglement we had. It took us 6.5 hours (7:30am-2pm) from Dex Creek to Kanangra Creek, including morning tea and a couple of other breaks. I'd expect some fitter/stronger parties would easily knock 1-2 hours off that time, but less competent navigation/not finding the pads could add many hours.
Coxs River - Mobbs Swamp: track up Yellow Pup is fine, the fires didn't seem to hit the lower half, there's a couple of overgrown places close to the summit. Track between Mt Yellow Dog and Mobbs exists, but is overgrown (more over head high regrowth) so much slower than previously.
Mobbs - Narrow Neck: track is relatively open
There's now a full trip report/photos on my website (
