Celebrate and take your choice of either Reims or Épernay for tours and tastings. It takes about an hour by rail from Gare de l’Est to travel into the French countryside. I advise making an appointment for tours and tastings on weekends, holidays, and peak travel periods. Raising a glass at two, maybe three Champagne houses is the limit for me on a day trip. On your next tour to Paris, take a day off and do an easy tour to the Champagne region.
