By plane:

The airline HOP! (a subsidiary of Air France) offers scheduled flights between Paris Orly airport (ORY) and Lannion airport (LAI) . There are morning and evening flights both ways, Monday to Friday, and a single flight on Sunday evening in each direction.

If you reach Paris with an international flight, it is likely your airport of destination will actually be Paris Charles de Gaulle airport (CDG). You can transfer between CDG and ORY airports using public transportation (RER B train from CDG airport station to Antony station, then Orlyval light train to ORY airport). An alternative is to use Air France coaches that directly link CDG airport terminals 1 & 2 to ORY West terminal, from which the flights to Lannion depart. This is only slightly more expensive, but offers the convenience of a door-to-door service. The estimated duration of the bus transfer is about 1 hour 15 minutes but you should allocate sufficient margins since the roads tend to be quite busy.

You can also fly directly from Paris CDG airport to Brest airport (BES), which is about 90 km away from Lannion (estimated driving time slightly above 1 hour).


By train

Train services from Paris depart from Paris Montparnasse main station. You should generally take a high-speed train heading towards Brest, with a connection to Lannion on the way,  either at Guingamp or Plouaret-Tregor station. The exact station where you should get off in order to take the connecting train to Lannion will be indicated on your ticket.

Paris Montparnasse station can be reached from CDG airport by either taking RER B train + metro (the most convenient connection being RER B train to Denfert-Rochereau station, then metro line 6 in the direction of Charles de Gaulle – Etoile to Gare Montparnasse), or using Air France coaches that provide a direct service.

If you are flying to Paris CDG airport, a possible alternative is to directly take a high-speed train service to Rennes (typically running 3 times a day) from where you will be able to carry on the journey towards Lannion. The main advantage of this solution is that it avoids you having to transfer between CDG airport and Paris Montparnasse.

You can plan your train journey from the French Railways site.

PERSYST is a few minutes walk away from Lannion station.
