I would like to know whether the Paris Visite Pass covers the transfer from CDG Airport transfer to city center hotel through RER B, if purchased at CDG Airport?
Note that you can also use a Mobilis ticket covering zones 1-5.– jcaronOct 4, 2018 at 7:41
As written in the official website
Valid for 1, 2, 3 or 5 consecutive days, the pass allows you to travel anywhere in Paris (zones 1 to 3) or in Paris and the Île-de-France region (all zones, including airport connections, Orlyval, Disneyland Paris and Château de Versailles).
So, yes, you can take the RER-B from the airport to Paris.
2Just to be clear, you need to buy the version that covers zones 1-5.– jcaronOct 4, 2018 at 7:42
