This was a great way to spend a day. Our tour guide and driver, Peter, was outstanding. He gave us some great insight into Vienna and Austria. We made several interesting stops in the lakes region along the way and when we arrived in Hallstatt, we had a 1 hour tour with a local guide, which was also very good. After the tour, we still had about 3 hours to explore Hallstatt on our own, have lunch, shop etc. before heading back to Vienna. It's a long day, but worth it!
