Which ski resort is best in Austria?

I have just comeback from niederau, was fantastic as a resort and some good slopes free bus ride between mountans at niederau and the schatzburgbahn mountain which is in Aufach.
Some excellent bars top middle and bottom

It really depends what you are looking for. Are you a boarder or a skiier? What level of ability do you have? Are you looking for night-life or skiing or both? Do you have kids or prefer an adult party? What pricing level, budget, luxury or in between? Austria, and Switzerland and France have them all

That's really subjective - there are a lot of good resorts and a lot of options to bring into the consideration.

Personally i like Kitzbuehel .... very long runs and a reasonable altitude.

Have a look at the Austrian National Tourism website - it will hepl strengthen your ideas a bit more. Good Luck:

try St Wolfgang and the Postalm ski area.
Great for beginners and some excellent off piste as well.
All depends on your expertise at skiing?
