Read the full post on how to get from Paris to Chateau Versailles by Train.
From Paris you can take a suburban “RER C” train to within 5 minutes walk of Chateau Versailles, ending at station Versailles-Rive Gauche.
Start your trip by going into any metro/RER station that you find around the city, which will be marked with a blue sign with an M or RER surrounded by a circle. From time to time you’ll see the metro marked only by the old style art deco Metropolitan signs. Take note of the station name when inside.
Your goal is to get to the RER C line, the yellow line that serves the western half of the Parisian suburbs. If you’ve got a day or week pass that’s good for at least Zone 4, skip this paragraph, else visit a ticket window in the station to purchase special ticket, since Versailles is in Zone 4, outside the coverage of normal Ticket t that you would get for traveling within Paris. At the ticket window or guichet [Gee-Shay] don’t panic. There’s a 50/50 chance the worker will speak English quite well and if not, they’ll understand “Chateau Versailles” [Shah-Tow Vher-Sigh]. Normally the metro worker will ask you whether you want a return ticket, by asking “Aller Rétour?” [Alleh-Ray-Tour] (or by making hand signs), which is simply two of the single tickets. Each ticket is currently (May, 2008 ) €2,80 so €5,60 for a return trip. Tip: don’t expect that your credit card will work at the ticket window. Many North American credit cards will simply not work at RATP/SNCF credit card machines so have cash on hand and don’t expect to use that 50 euro note either. Small bills or coins are best. Go ahead and buy Aller-Rétour return tickets to save a bit of time (unless you plan on sneaking off the tour path at the chateau and spending the night there).
