Option 2: Train
The train is still a viable choice for this route and is actually the most popular means of travel for tourists not using a car. It does require a couple of changes, however, so it is best to know what you’re walking into before you land.
Pros & Con
The trip begins with the RER B line from CDG to central Paris, where you will transfer to Châtelet-Les-Halles. From there, you’ll head towards Gare de Lyon (either by a short RER ride or a walk through the crosspassage) and take a Transilien Line R train towards Montargis, Sens or Montereau, which all stop at the station of Fontainebleau-Avon. The good news is it’s all on well-established commuter lines, frequent and no booking required. The drawback is that there are two changes to make, quite a lot of walking through crowded stations, and the last train in the region is less frequently on schedule than the RER lines that feed into it.
Upon arriving at Fontainebleau-Avon, you have not yet reached the château. It is located a couple of kilometres out of town, so to reach the station take the local bus to the city centre (bus line 1) or walk, which may take 20 to 30 minutes depending on how heavy your bags are. It’s an additional little action, but one which surprises first-time visitors.
Train Tickets & Booking
A single ticket is usually valid for the entire trip from CDG to Fontainebleau-Avon as all three legs are not on the separate main lines, but on the Ile-de-France regional network. There is a machine available in the terminals of the CDG airport to purchase this ticket at the point of sale, and it is possible to book it in advance using the Ile-de-France Mobilités app; the price is generally between €18 and €26 per adult. No seats need to be reserved on any of these services, which makes things easier than a booking on any of the mainline SNCF services, but of course, means standing room only during busy periods, especially on the Transilien leg heading out of Gare de Lyon.
Prices are usually reduced and/or free for children, depending on their age; check for current rates at the machine and do not assume that they are the same as the previous year.
Train Travel Time & Frequency
The opening leg of the RER B service from CDG is usually fairly frequent, operating from 05:40 to 22:45 with service every 10 – 15 minutes most of the time, so you will likely not have to wait a long time. The Transilien R service from Gare de Lyon is, however, less frequent (usually every 30 minutes or an hour depending on the time of day), and it is this last stretch that has the greatest variance in total journey time. All in all, the average door-to-station trip is about 1 hour 30 minutes to 1 hour 45 minutes depending on the combination of legs, though the faster end of the range is those where the timing of the legs is optimal.
Option 3: Bus
This one area of Fontainebleau is not particularly clean, and it’s best to be honest about it rather than to pretend it’s otherwise. The bus route is actually two buses joined together because there is no direct bus service from CDG to Fontainebleau.
Bus Routes & Stops
The first point is the airport shuttle into central Paris from terminals 1 or 2: Le Bus Direct, from terminal 3: RoissyBus. It drops you at a central location, usually around Opéra, where you would walk to a coach station, most often Paris-Bercy, for the next leg. Then BlaBlaCar Bus service goes on to Fontainebleau, where it is possible to walk to the town centre for a few minutes. It works, but it does require two bookings, two operators, and a bit of navigating in the middle of Paris with luggage between two appointments.
Bus Fares & Schedules
The airport leg usually ranges from €12 to €18, and is fairly common during the day. The journey to Fontainebleau from the onward coach costs significantly less (usually €7 to €14 if booked in advance; check timetables before booking) but services are not running on a regular rolling service so check the timings before booking this route. The total journey time with the transfer through Paris is about 2 hours 30 minutes – 3 hours, which is a comfortable time though the price is attractive. It’s a good idea when your time is limited and your wallet is empty, but it’s not the right one when you’re pressed for time and have a lot of bags to coordinate two changes with.
Comparison Table: Cost, Time, Convenience
| Mode | Travel Time | Cost | Convenience | Best For |
| Private Transfer / Taxi | 1h 15m – 1h 30m (up to 2 hrs in traffic) | €140 – €190 | Highest — door-to-door, no transfers | Families, tired flyers, heavy luggage |
| Train (RER + Transilien) | 1h 30m – 1h 45m | €18 – €26 | Moderate — two changes, steady frequency | Solo travellers, budget-conscious visitors |
| Bus (Airport Shuttle + Coach) | 2h 30m – 3h | €20 – €30 | Lowest — two separate bookings, longest ride | Budget travellers with plenty of time to spare |
When compared side by side, it’s more obvious than on a shorter suburban ride, and largely because the distance magnifies all of the trade-offs. The private transfer is the most expensive by far, but it also saves nearly an hour over the train and much more than an hour over the bus, which is of little consequence on this long a journey.
The train falls somewhere between the extremes: not particularly cheap but not particularly expensive; it’s not so fast that you can’t wait an hour or two for the changes, and it’s good enough that most travellers who travel alone or on a shoestring budget manage just fine. You win on the price, but it’s demanding a double booking, a transfer in central Paris, and nearly three hours for the return.
When you’re looking to save as much hassle as possible, and you’re willing to pay for it, the transfer is the obvious choice. The train is very good for the couple of changes in station if you are comfortable with that and do not want the costs to be high. Unless it is more important for you to save every euro you can than to save time, then the bus doesn’t make any sense.
Conclusion
It’s a long distance from Charles de Gaulle to Fontainebleau, so your decision here has more importance than it would have if you’re traveling a shorter distance. That isn’t enough to make it worth the extra cost, but when you’re very tired or traveling with children, a private transfer is also welcome. The train is a reliable middle ground option for those who are comfortable with a few transfers and a brief local bus to the end. It works, but only for the very flexible bus schedule and for people who do not need to be anywhere at a moment’s notice.
When traveling this distance, a pre-arranged private transfer in advance with an operator such as T2 Transfer will make a stressful cross-Paris journey easy and hassle-free, as you will have a single door-to-door transfer. Whatever method you opt for, the forest, the château and the tranquil streets of Fontainebleau are a worthwhile trip out from CDG.
