I have used the Voyage Virtuel for years in my community college French classes. I have linked to it on the French Resources page of my web site. I have also assigned my students tasks that require its use.
The key feature of the Voyage Virtuel is its clickable map, that draws the student deeper into the individual towns featured. There are photos taken by the author that capture geography, culture and cuisine. The supplemental materials and external links are also very helpful.
The Voyage Virtuel is one of many pages of a much larger site entitled Civilisation Francaise. Each page covers a topic like Cooking, Economy, Education, History, just to name a few. Each page provides useful information followed by questions in different formats to test student knowledge, more than 500 photos depicting everyday French life, audio and video exercises, external links, related films and a bibliography.
On the Civilisation Francaise home page,the author clearly specifies any plug-ins necessary for audio and video viewing. The whole site is easy to navigate and the Voyage Virtuel is no exception.
