From the Paris airports to Rouen

By public transport, first to Paris-Saint-Lazare: from Charles de Gaulle, RER B and change; from Orly, metro line 14, which goes direct to Saint-Lazare. There, a train to Rouen, paid for separately with SNCF. By car, Charles de Gaulle is an hour and three quarters away and Beauvais an hour and a half.
