Bratislava, Brno, Praha, Salzburf, Insbruk and so on is obvious. I'm sure that there must be a lot of interesting places near Vienna that are not that famous - hope to find out them here =)
While it is still quite warm firstly I'm interesting in nature, but other options are also very welcome!
Also maybe you can name some place that are worth to visit to find out "true Austria", not just Austria from the tourist point of view.
Thanks in advance.
