CDG has three main terminal areas, Terminal 1, Terminal 2 (which is massive and split into sections A through G), and Terminal 3. All of them are connected by a free internal shuttle called CDGVAL<\/strong>, which runs every 4 minutes from 4:00am to 1:00am. So no matter where you land, you can get to the right departure point without paying anything extra.<\/p>\n\n\n\n If you want to get into Paris quickly without spending a fortune, the RER B train<\/strong> is the gold standard. It runs on a dedicated rail line, meaning it’s completely unaffected by road traffic, and it drops you right in the heart of the city.<\/p>\n\n\n\n From any of these stations, you can jump onto the Paris Metro to reach virtually anywhere in the city. Keep your RER ticket, it’s also valid for Metro transfers within central Paris for up to 90 minutes.<\/p>\n\n\n\n Ticket machines are available at both airport train stations and accept coins and credit cards (though some foreign cards have been known to have issues, carrying some euros is always a good backup). Tickets are also available via the \u00cele-de-France Mobilit\u00e9s<\/strong> or RATP apps<\/strong> on your phone.<\/p>\n\n\n\n Important:<\/strong> Always hold onto your ticket for the entire journey, you’ll need it to exit at your destination station.<\/p>\n\n\n\n The RoissyBus<\/strong> (now operating as line 9515\/9517) is a direct express bus running from CDG terminals straight to Op\u00e9ra Garnier<\/strong> in central Paris, one of the most central and well-connected spots in the city. It’s a comfortable ride with WiFi and luggage space, making it a popular choice for travelers with big bags.<\/p>\n\n\n\n The Navigo pass (all zones) and Paris Visite card are also valid on RoissyBus. Contactless payment is accepted on board.<\/p>\n\n\n\n The RoissyBus costs a bit more than the RER B and takes longer, but if your accommodation is near Op\u00e9ra, Haussmann, or the 9th arrondissement, it’s genuinely the most convenient option since it drops you very close to where you need to be.<\/p>\n\n\n\n If saving every euro matters, Bus Lines 350 and 351<\/strong> are the cheapest way to get from CDG into Paris at just \u20ac2.50 per trip<\/strong>. The trade-off? They’re slower, make more stops, and don’t go to the most central locations.<\/p>\n\n\n\n From either terminus, you can continue by Metro. Standard Navigo passes and t+ tickets are also valid. Bus stops are at Exit 32 of T1, Exit 9 of T2A, Exit 11 of T2D, and Roissyp\u00f4le Bus Station.<\/p>\n\n\n\n These buses are a great backup option when there are disruptions on the RER B, and perfectly fine if you’re not in a rush.<\/p>\n\n\n\n Landing at 2am? The Noctilien night buses<\/strong> have you covered:<\/p>\n\n\n\n Both buses stop at Roissyp\u00f4le Bus Station and near Terminal 1. Tickets cost \u20ac4.30 (or 2 standard t+ tickets), and Navigo passes are valid.<\/p>\n\n\n\n Official Paris taxis operate on fixed flat rates<\/strong> from CDG to the city center, which is actually useful since you know exactly what you’ll pay before getting in.<\/p>\n\n\n\n Taxi stands are located outside every terminal. Only use official taxi ranks<\/strong>, never accept rides from individuals approaching you in the arrivals hall, as these are unofficial and almost always overpriced.<\/p>\n\n\n\n Journey time is typically 45\u201360 minutes in normal traffic, but can stretch longer during rush hour. Cash and card payments are both accepted, though carrying some euros is always wise.<\/p>\n\n\n\nOption 1: RER B Train<\/strong><\/h2>\n\n\n\n
