dont no whether it has changed or not but april will be going down a blackberry infested gorge .both time i did it were eraly summer or spring .dont go down whole gorge to snowy but head back up the north side after the big waterfall up the spur that ends on the bend in the road down to Mclliops bridge
I think there are about 10 or 15 gorges in the area only other one I have been to is reedy creek gorge .Rob Jung had some great article in magazines about all the gorges in the late 70 early 80s
How about rocky valley gorge above bogong village track goes to guaging station at he bottom of the gorge and another track cross above the gorge . Another one in that area is upstream (500 m ?) of the main bridge where road crosses from fainter side to falls creeek side of river over Mt mckay creek and on the fainter side .
