|RoissyBus/Bus 350 CDG Airport Bus|
|The RoissyBus and Bus 350 airport buses, operated by RATP, provide cost-effective airport shuttle bus service between Paris-Charles de Gaulle Airport and Place de l'Opéra in central Paris for a lower fare than the Air France bus.|
The RoissyBus airport bus, a service of Paris's RATP public transport system, shuttles passengers between all 8 of the terminals at Paris-Charles de Gaulle Airport and Place Charles Garnier, next to the Place de l'Opéra in central Paris (map) for 11€ one-way/single.
(Place Charles Garnier is where rue Scribe meets rue Auber. The bus stop is on rue Scribe at the corner of rue Auber, across rue Scribe from the Palais Garnier.)
RoissyBus service begins at 05:45 am from the Place Charles Garnier in central Paris, at 06:00 am from Aéroport Paris-Charles de Gaulle. The RoissyBus stops at all eight of CDG's terminals (except Terminal 2G, which you reach by shuttle bus from Terminal 2E.)
Buses run every 15 minutes until 20:00 (8:00 pm), and every 20 minutes from 20:00 to 23:00 (8:00 pm to 11:00 pm). The ride takes about 60 minutes in average mid-day weekday traffic. If you travel at morning or evening rush hour, particularly if you're going into the city in the morning rush, or out to the airport in the evening rush, you must plan at least 50% more time.
Note that there is no toilet on the bus, and no bus office with a toilet, at the rue Scribe/Place Charles Garnier bus stop, so come prepared.
RoissyBus Tickets & Fares
The one-way/single fare is 11€, substantially less than the Air France bus and just a bit more than the RER B suburban train—but the train, not having to contend with Paris traffic like the bus does, is usually faster, and the train serves more destinations in central Paris. More...
There is a ticket machine in the bus stop shelter at rue Scribe/Place Charles Garnier (map) from which you can buy a ticket using a chip credit/debit card or euro coins, but not paper money. You must validate your ticket (composter) when you board the bus: insert your ticket in a validator machine and it will stamp the date and time on the ticket.
You may also purchase your ticket from the driver using coins, euro notes/bills, or credit card when you board the bus. The driver will give you a receipt which serves as your ticket.
Here's the official RoissyBus web page.
Another RATP service is Bus 350 which connects Aérogare 2 with the Gare de l'Est in Paris. The fare is the lowest—6€—or the equivalent of 3 normal Métro tickets (ticket t+). From Gare de l'Est, with one more Métro ticket, you can go anywhere in Paris for a total fare of less than 8€.
But the trip is not fast. From CDG Airport to Gare de l'Est can take 60 to 80 minutes.
RER B & Air France Bus
You should also consider the RER B suburban train to travel between Paris-Charles de Gaulle Airport and the center of Paris, and you may want to consider the more expensive—but no faster nor more comfortable—Air France airport buses. More...
