If you are bored with dull beaches and hot-dog stands... go discover Austria!
We were in Klagenfurt a long-long time ago with my sister and a group of kids from school to learn German, and we enjoyed it a lot.
It's a wonderful place, pieceful, with a beautiful scenery, really idealic if you'd just like to get back to nature. Austrians are really lovely people, helpful, appretiating that we tried to speak German :-D so we had a great time. Weather was great during the summer, warm, fresh, and it was only raining during the nights :-)
I'm recommending it for everyone who seeks a getaway from cities - for a week or two just to be among those amazing mountains, wonder around where christal clear lakes come you by and suddenly you will hear your own thoughts! :-)
