Actually you've only been to the worst places in Austria if you only visited Vienna and its surroundings.
I've skied there many times and hiked the area in and around Salzburg. My kids still talk about the sleigh ride we took one night. Shown below with our driver. Also shown is a couple of guys we met in a pub we stopped in (for, um, hot chocolate). After seeing these large horns on the wall, I asked if they still work. Next thing I know, we are back outside listening to them being played!

The specific good memory comes from, after visiting Vienna, staying at the Richard Lowenherz in a small medieval village (Durnstein) just outside of Vienna on the Danube. It was completely unplanned and we ended up there as essentially an accident. But, this occasion ended up being one of our very favorite weekends of our 25 year marriage.
Anyhow, Austria is worth being on anyone's bucket list, IMO.
