Much more than just fantastic Champagne
There are regular daily Eurostar services from London Waterloo and Ashford to Paris. From Paris trains take about 1 hour 40 minutes to Reims, or about 75 minutes driving time on the A4 and A26 motorways.
If you are travelling by car, a Eurotunnel crossing from Folkestone to Calais (Coquelles) or a sea crossing from Dover to Calais (sailing time between 1 – 2 hours), or Dover to Boulogne (sailing time about 50 minutes) are the most convenient for the journey to Reims.
From Calais or Boulogne to Reims, the driving time takes about 2½ hours, with a toll charge of about €20.
