Hello fellow travelers,
A recent post prompted me to do a bit of research on this issue... Thanks Kim! (from Paris)!
This information may be useful especially if you're planning to visit the Château de Versailles, during your Paris visit this summer.
According to the Château de Versailles official website: http://en.chateauversailles.fr/prepare-my-visit-/single/access
From 16 July to 27 August, the RER C line is closed between Paris Austerlitz and Javel. You can go to Javel thanks to:
the metro 10 from Paris Austerlitz and Saint-Michel Notre Dame
(station Cluny – La Sorbonne),
the replacement buses from Invalides, Pont de l’Alma and Champ de Mars Tour Eiffel.However, we advise you to use the SNCF trains from the Saint-Lazare
and Montparnasse train stations.
So what does this mean?
If you want to travel on the RER C from Paris to the Palace of Versailles,
you will have to get to the Javel station via Métro line 10 (yellow) or via bus.

As stated above, you may also travel via SNCF trains, but the RER C is more direct & faster, as far as I understand.
Here are a few helpful websites:
