Option 2: Train
Pros & Cons
The train is the most popular public transport option for getting from CDG into Paris, and it’s genuinely good when conditions cooperate. The RER B line connects Charles de Gaulle Airport directly to central Paris, stopping at major interchange stations including Gare du Nord, Châtelet-Les Halles, and Saint-Michel Notre-Dame. It’s fast, it runs frequently, and the fare is among the lowest of any option on this route.
The cons are real though. The RER B has a mixed reputation for reliability, with delays and overcrowding during peak hours that can turn a 35-minute journey into a considerably longer one. If you’re travelling with large luggage, the carriages are not designed with that in mind. Getting on and off at busy stations with a suitcase requires a bit of effort, and not all platforms have lifts.
There’s also the last-leg question. The RER B will get you into central Paris, but it won’t get you to the Radisson Blu’s door. Depending on which property you’re heading to, you’ll need a Métro connection, a bus, or a short taxi from the nearest RER station. Factor that in when comparing journey times.
Train Tickets & Booking
A single RER B journey from CDG to central Paris costs €11.80 as of 2025. Tickets are available from machines at the airport stations, which have English-language options. You can also use the RATP app or Ile-de-France Mobilités to plan your route and check live departures before you travel.
One thing worth knowing is that standard Paris Métro tickets and Navigo passes do not cover the CDG airport zone. You need a specific CDG ticket or a Navigo pass loaded with the correct fare. Ensure to check this before you travel to avoid any issues at the gate.
Train Travel Time & Frequency
The RER B from CDG to Gare du Nord takes approximately 25 to 35 minutes. Trains run every 10 to 15 minutes during the day, making it a frequent and accessible option. Services start early and run until around midnight, which covers most flight arrival windows.
Once you’re at your Paris interchange station, add the time for your onward connection to the Radisson Blu. Total door-to-door journey time typically sits between 50 minutes and 1 hour 15 minutes depending on your specific destination and how smoothly the connections run.
Option 3: Bus
Bus Routes & Stops
Several bus services connect Charles de Gaulle Airport to Paris, with different routes covering different parts of the city. The main options are Le Bus Direct (formerly Les Cars Air France), which runs comfortable coach services to key Paris locations including the Arc de Triomphe, Trocadéro, and Gare de Lyon, and the Roissybus, which runs directly between CDG and Opéra in central Paris.
The Roissybus is the most straightforward option for most travellers. It departs from all CDG terminals and drops you at Opéra, from where the Métro or a short taxi ride can get you to the Radisson Blu. Le Bus Direct routes cover more of the city but take longer due to the route design. You can check Le Bus Direct or the RATP Roissybus for current routes, stops, and any schedule changes before you travel.
Bus Fares & Schedules
The Roissybus fare is €16.20 for a single journey. Le Bus Direct fares start from €17 and vary by route and destination. Both can be booked online in advance or purchased at the airport on the same day.
Roissybus runs approximately every 15 to 20 minutes between 6am and 12:30am. Le Bus Direct frequencies vary by line but generally run every 30 minutes. The journey times also depend on traffic. The Roissybus to Opéra takes around 60 to 75 minutes under normal conditions, and longer during peak hours when Paris traffic slows considerably.
The bus is the most affordable public transport option on this route. It’s a comfortable ride with luggage storage, which makes it more practical than the RER B for travellers with larger bags. The tradeoff is time. Paris road traffic is unpredictable, and a journey that takes 60 minutes on a quiet Sunday morning can take considerably longer on a weekday afternoon.
Comparing All Transport Options
| Option | Estimated Cost | Journey Time | Convenience | Best For |
| Private Transfer (Paris Airport Pickup) | €56–€65+ | 30–50 mins | High | Families, business travellers, groups |
| Train (RER B) | €11.80 | 50–75 mins total | Medium | Solo travellers, light luggage |
| Bus (Roissybus / Le Bus Direct) | €16–€17 | 60–90 mins | Medium | Budget travellers with bags |
The private transfer wins on simplicity and predictability. The train wins on price for solo travellers who travel light and don’t mind connections. The bus sits in between, more luggage-friendly than the train but slower and dependent on road traffic. Your situation determines which one makes the most sense.
In all honesty, your Paris trip begins the moment you land. However, getting from Charles de Gaulle to the Radisson Blu doesn’t need to be the part of the trip you’re still recovering from when you check in.
All three options in this guide will get you there. But if you want to arrive at the hotel relaxed and on schedule with no logistics to sort out on the day, a pre-booked private transfer is the option that delivers that consistently.
