We will be driving up from Domme to Paris and will be dropping our rental car off in Versailles train station so we don't have to drive into the city. I'm sure there are plenty of trains that get you into Paris. We are staying in the 7th so does anyone know which one we need to take. Also does anyone know if there is any luggage storage available if we felt like going to Versailles that day? Thanks
Take the line that is closest to the drop off, or, if you go to Versailles, that is closest to Versailles. You may not want to do that by the time you arrive, you wouldn't have that much time. Sorry, I do not know about left luggage, maybe someone else can help.
The Rive Gauche Station in Versailles will have trains most convenient to the 7th. But the Chantiers Station also would work fine. Make sure you take the train into Montparnesse Station in Paris. Then just take a Metro to your hotel. Most likely your car return is near one of these stations. Both are also within a 20 minute walk of the Chateau. I believe the Chateau has luggage storage, and possibly the Rive Gauche Station.
