Champagne is a name of great resonance, conjuring up images of celebration and the world-famous cathedral of Reims. The so-called "sacred triangle of champagne," linking Epernay, Reims and Châlons-sur-Marne, is like a magnet for wine lovers. Visiting these prestigious champagne houses, who all rival in quality and prestige, learning how champagne is made as well as tasting their best bottles is a truly unforgettable experience. The new TGV train takes 45 minutes from Paris to Reims. From Paris, a full day visit must be programmed.
