Although Austria has been popular among tourists for years, you will also find places outside the main routes here. And among them the picturesque town of Krems , which is the eastern gate to the Wachau Valley. Take a walk around the amazing Grüner See . This lake in Styria is famous for its tremendous water fluctuations. Also visit Bregenz , which, although situated on the popular Lake Constance, offers a pleasant, intimate atmosphere beyond the peak of the summer season.
