There are non-stop flights to Paris (CDG) daily from all over the world.
Once you arrive in Paris the high speed train station is right in the airport and it’s a 3.5 hour train ride to the Aix en Provence TGV station.
La Belugue is just 40min away from the train station and voila, welcome to Provence!!
Or you can take a short connecting flight to Marseille Airport (MRS) and then its just a 1 hour drive to La Belugue.
