Has been descended a fair few times, ends in the ‘swimming hole’ of Siberia Hut, so you can expect some observers when you arrive.
No info on the canyon, but from the valley you can see a bunch of stacked waterfalls… I’d be taking a drill and at least 2x60m ropes and a staunch bushbashing mojo.
Fixed wing access in (and out) of the valley and a hut right there (needs booking). Pretty gorgeous place to spend a few days.
