Using the Autoroutes (which one has to pay a toll). After crossing the Channel by ferry or Eurotunnel to Calais the best route is via Reims, Troyes and Dijon to Beaune (which is the nearest exit to Chagny) and then by ordinary road to Chagny. Travelling using Route Nationale roads, which are toll-free, can take longer – two or more days at will.
By rail – Letchworth to Kings Cross then walk to St Pancras to catch Eurostar to Paris. The majority of these Eurostar trains go to the Garde du Nord in Paris which then has to be crossed using the Metro or the RER to the Gare du Lyon for a TGV train to Dijon and from there a local train to Chagny. A few Eurostar trains go to Lille where it is possible to catch a TGV train to Dijon without the worry of crossing Paris.
