Quick Answer
The best overall way to travel from Paris Orly Airport (ORY) to Sorbonne University is via the RER B commuter train. The journey involves taking the automated Orlyval shuttle to Antony station, then the RER B to Luxembourg station. Total travel time is approximately 45 to 60 minutes at a cost of around €14.30. For the cheapest option, take the Orlybus to Denfert-Rochereau (€9.50) and connect via Metro Line 4 or RER B (total under €12). A taxi is the most convenient door-to-door option but costs €35 to €50+.
Train & RER: The Most Efficient Route to Sorbonne
The Réseau Express Régional (RER) B line is the primary rail link connecting Orly Airport to central Paris and the Latin Quarter, where Sorbonne University is located. This is the method preferred by most students and seasoned travelers for its balance of speed, frequency, and cost.
Key Advantage: The RER B terminates at Luxembourg station, situated in the Jardin du Luxembourg, less than a 5-minute walk from the historic Sorbonne buildings.
Step-by-Step Guide: RER B via Orlyval
- Find the Orlyval: Follow signs for “Paris by Train” or “Orlyval” from any terminal (Orly Sud/West or Orly Ouest/North). The shuttle station is centrally located.
- Take the Orlyval: This automated, driverless light rail runs every 4-7 minutes. The 8-minute journey takes you to Antony station, the connection point for RER B. A combined ticket (Orlyval + RER) is required.
- Board the RER B: At Antony, follow signs for “RER B Paris.” Take any train with “Paris” as its final destination (e.g., Mitry-Claye or Aéroport Charles de Gaulle). The ride to Luxembourg station takes about 25 minutes.
- Alight at Luxembourg: Exit the station onto Rue de l'Abbé de l'Épée. The Sorbonne's main entrance on Rue des Écoles is a short walk north.

Alternative Rail Route: Tram T7 to Villejuif-Louis Aragon
For those near Orly Sud, the Tram T7 offers a slower but scenic route. It connects to the Metro Line 7 at Villejuif-Louis Aragon. From there, take Line 7 to Place Monge and walk 10 minutes. Total time: ~75-90 mins. Cost: Single Metro ticket (€2.10). This is a backup option if RER B experiences disruptions.
Bus: The Budget-Friendly Choice
Buses from Orly are significantly cheaper than trains and offer direct connections to key Metro hubs. They are ideal for travelers with light luggage and flexible schedules.
Option 1: Orlybus (Official Airport Shuttle)
- Route: Direct service from both Orly terminals to Denfert-Rochereau in central Paris.
- Travel Time: 30-40 minutes, depending on traffic.
- Frequency: Every 8-20 minutes.
- Cost: €9.50 one-way. Tickets can be purchased from machines at the bus stop or on board.
- Connection to Sorbonne: At Denfert-Rochereau, transfer to the Metro Line 4 (direction Porte de Clignancourt) and alight at Saint-Michel or Odéon. Alternatively, take the RER B (2 stops north to Luxembourg).
Pro Tip: The Orlybus uses dedicated bus lanes for part of the journey, making it more reliable than regular buses in moderate traffic.
Option 2: Public Bus 183
For the ultimate budget trip (using a standard Metro ticket), take public bus 183 from Orly Sud to Porte de Choisy. Then, transfer to Tram T3a and Metro Line 7. This journey costs only €2.10 but takes over 90 minutes with multiple changes. Only recommended for the very patient and experienced.
Option 3: Night Bus (Noctilien N22)
Operates from approximately 00:30 to 05:30, connecting Orly to Châtelet in central Paris. From Châtelet, you can take a taxi or the night metro (if operational) to reach the Latin Quarter. A standard night bus ticket is €2.10.
Taxi & Ride-Share (Uber, Bolt): Door-to-Door Convenience
This is the most straightforward but expensive option. Official taxi ranks are located outside each terminal (follow “Taxis” signs).
Official Taxis: Fixed Rates to Paris
Taxis from Orly to destinations on the Left Bank (Rive Gauche), which includes Sorbonne University, operate on a regulated fixed fare.
- Day Rate (10 AM - 5 PM): €35
- Night/Early Morning/Weekend Rate: €50
This fare covers all passengers (up to 4) and luggage. Always ensure the meter is set to the correct fixed fare (“tarif fixe”). The journey takes 30-50 minutes depending on traffic.
Ride-Share Services (Uber, Bolt, FREENOW)
Pick-up points are designated at each terminal (often in car parks). Prices are dynamic and can vary dramatically:
- Standard UberX/Bolt: €35 - €60.
- Uber Comfort/Green: €45 - €75.
- During peak hours or bad weather, prices can surge above €80.
When to Choose a Taxi/Ride-Share:

- Arriving late at night after public transport has reduced service.
- If you have mobility challenges.
Warning: Avoid unlicensed drivers soliciting inside the terminal. Only use official ranks or the app.

Traveler Tips & Insider Insights
Luggage & Navigation
- Beware of Stairs: Many Paris Metro and some RER stations have limited or no elevators/escalators. If you have large suitcases, the RER B at Luxembourg has an exit with fewer steps, or consider a taxi for the final leg.
- Pickpocket Awareness: The RER B line and crowded transfer stations (Châtelet, Denfert-Rochereau) are known for pickpockets. Keep valuables secure and luggage close.
- Google Maps / Citymapper: These apps provide real-time public transport routing, including disruptions. They are indispensable for navigating Paris.
Timing & Purchasing
- Avoid Peak Hours: Weekdays from 8:00-10:00 and 17:00-19:00 see extreme crowding on RER and Metro. If your flight lands then, consider a slightly pricier but more comfortable Orlybus or be prepared for a packed train.
- Buy Tickets in Advance: Purchase your Orlyval+RER ticket or Orlybus ticket from the clearly marked vending machines before queuing for the shuttle/bus. Machines accept chip & PIN cards and cash.
- Validate Your Ticket: If using a paper ticket, you must validate it (composter) at the orange machines before boarding the Orlyval and again before entering the RER platform at Antony.
Upon Arrival at Sorbonne
The Sorbonne campus is spread across multiple buildings in the 5th arrondissement. Confirm your specific department's address. The main historic building is at 17 Rue de la Sorbonne, 75005 Paris. Luxembourg RER station places you closest to the arts and humanities departments.
