Going to Versailles
What is the cheapest and easiest way to get from Beauvais to Versailles?
I'm not sure if it's the easiest way, but I suggest taking the airport shuttle into Paris and then take the RER C to Versailles. You can get the RER C in Porte Maillot where the shuttle bus arrives. You need to take the RER C5 or C7 depending on where you want to get off in Versailles.
