Ok went for a drive up there today (it was rather moist....and not cool coming down the back side!)
The best one I think its the "Grey Gum" picnic area. There is a carpark, shelter sheds and toilets...and it looks rather new. Thats the one on the southern side of ch7
There are about 7 picnic areas all up so there are plenty to choose from. Theres a great one down the bottom where the tables are right on the carpark. You can back ur car right up to the tables (run into them if you want) but I think up the top will be more fun!
Some of the picnic areas are on blind corners and I don't want anyone totaling their cars! The worst one is on a streach of about 150m and at each end there are climbing blind corners! (rather tricky to get out of if its busy!)
