Went to Tassie April '04 and loved it! While it's true many of the highways are very winding I found them to be in pretty nick- except for the highway between Tarana and Port Arthur. Also there is no lighting on that one.
Pretty much ALL areas of Tassie are scenically beautiful. Cradle Mountain is a "must"- it's so completely awesome! We travelled via Sheffield along Lake Barrington. I'd also recommend Tasmazia on Staverton Road, Promised Land. Yes. there really IS a place called that, there is also the Village of Lower Crackpot, Nowhere Else and Paradise.
If your'e going far NW check out Stanley and the "Nut" and further on there is (sorry forgot the place name) which is said to have the cleanest air in the world.
Lake St. Clair Nat. Park is great. Also check out Mole Creek and the caves- there's Marrakoopa (wet) and King Solomon(dry).
In the SW lies the Huon Valley and the Tahune Airwalk, breathtaking scenery all national forests. Also go to the top oh Mt. Wellington which overlooks Hobart and gives you a 360 degree for about 100 kms.
Sorry this is so long, but whenever I plan a holiday, I start my research about 18 months beforehand and get one of those loose leaf holders students use and fill it with lots and lots of cutouts and info plus my own pictures etc. All I have to do is pull it out of the bookcase and Voila!
Have a nice day, Whistler.
