I'm more into mass transit myself and so prefer to take the train. There is a station in each terminal (follow the signs to the ';gare';, then follow the signs to ';Paris by train';). Then buy a ticket at the blue SNCF machine (to Paris). It will cost 8.20 euros and it accepts credit cards. Then look for the next train to Paris (during the day and night there is one every 5-10 minutes). This train, by the way, is called ';RER B'; but you don't really need to know that. Take this train to station ';Denfert Rochereau'; which is the station nearest Montparnasse. You can then take a very quick metro ride to Montparnasse on Line #4 in direction Clignacourt (two stops from Denfert Rochereau).





total cost: 8.20 for train, then 1.50 for metro = 9.70 euros.





It's much less expensive, less touristy, and friendly to the environment. It's also the ';paris'; way to get around.





Of course, if you have alot of luggage forget all this and take a taxi. Shuttles are a pain and hard to find (even when you arrange one). Taxi is right there! easy, but expensive (up to 50 euros since Montparnasse is way the heck down south on the other side of Paris).

Follow Zafir's advice, is the best. Alternately, you may take a cab, is around 30...40 EUROS from CDG to Montparnasse neighborhood (depends on your destination)
I've used this one. http://www.parishuttle.com/ They are all much alike.
The Air France shuttle from CDG terminates at the Gare Montparnasse. It costs about 16euros, and you should be able to find your way from Montparnasse station.
