Champagne-Ardenne (list of hotels) is in the northeast of France, bordering Belgium. It consists of four departments: Aube, Ardennes, Haute-Marne, and Marne.Its rivers, all of which flow west, include the Seine, the Marne, and the Aisne. The region has three autoroutes, totaling 460 km:

A4 connecting Paris and Strasbourg and serving the Reims metropolitan area
A5 connecting Paris and Dijon and serving Troyes and Chaumont
A26 connecting Calais and Dijon and serving Reims and Châlons-en-Champagne
A34 connecting Reims and the Belgian border and serving Charleville-Mézières
The rail network includes the Paris–Strasbourg line, which follows the Marne Valley and serves Épernay, Châlons-en-Champagne, and Vitry-le-François. The LGV Est TGV line also connecting Paris and Strasbourg will open in 2007 and will serve Reims with a new train station in the commune of Bezannes.

The region's canals include the canal lateral to the Marne and canal from the Marne to the Rhine, which connects to the Marne at Vitry-le-François. These are petit gabarit canals. It is famous for its sparkling white wine (champagne).

The Vatry International Airport, primarily dedicated to air freight, has a runway 3650 m long, yet it is often unused. The airport is in a sparsely populated area just 150 km from Paris. Some people say it is a good candidate for transformation into a third Parisian airport. Les verts (the French green party) supported such a move because the resulting noise pollution would affect fewer people than an airport closer to Paris.
