Kosciuszko NP is a nice park , to see all the sites you would have to live forever. But we have seen only a tiny bit and most of it was under ground. Yes the Yarrangobilly Caves is a must see. The staff at the caves were absolutely faultless, I could have spent days up there exploring the area. The Tumut CP was a bit quiet , not many people camping there at the moment . $31 for a powered site , on the net it said $ 29 ,hmmm they must have seen us comming.
