I did Clyde mountain once on my way back from Canberra (took 4 hours with scenic stops in Batemans Bay, Nowra and Kiama. I found it a POP compared to Kangaroo Valley Road... I've driven many roads more dangerous then that, in fact I grew up on them in the Adelaide Hills. It is a great road, but spoke to some friends after I had driven that way completely off the cuff and they mentioned just how great a road it was I just went.. meeeeye.. but I was keeping to the speed limits though, as there were many coppers (as always) on that particular road... and it was the middle of the ski season
