Help me pick a place in Austria

[Shilly]

Hey everyone,

My roommate and I have been throwing around fall break plans. We're thinking of flying from Paris to Prague, then heading to Austria. Our first stop will be Vienna. But after that, I'm looking for a smaller place that would have more of a "natural beauty" element. Right now Zell am See is at the top of my list.

Do you have any advice? It must be connected to rail; accommodations for < 35 euros per person per night is a plus.
