Austria

As a seasoned traveler, the Insight Guides series have become my favorite travel companion. They are not the traditional guides that tell you the cheap places to stay and eat, rather they are detailed guides to the history, culture and things to see in the countries you will be visiting complete with great photos. They are well researched and I learn things about the country that even the natives don't know. If you are looking for a "where to sleep" kind of guide, you will have to purchase a second, more traditional travel book (like Lonely Planet, etc.). I personally would not think about visiting a country without first reading the "Insite Guide."
