Bus line: Manosque – Forcalquier – Digne – Sisteron – Gap
This regional coach links Marseille Provence Airport (MRS) with towns like Manosque, Forcalquier, Digne-les-Bains, Sisteron, and Gap, so it’s the airport’s direct public link into the Alpes-de-Haute-Provence and Hautes-Alpes area. It usually departs from the main coach park in front of Terminal 1, which is the hub for most intercity buses at MRS.
You buy tickets either at the coach ticket counters inside T1 or directly from the driver at the bus, and fares are typically lower than piecing together a TER train plus a local bus from Marseille Saint-Charles. The service runs point-to-point from the airport, which cuts out the 20–25 minute detour into central Marseille that you’d have with the train or airport shuttle.
Coaches serving Manosque, Forcalquier, Digne, Sisteron, and Gap tend to run in blocks around flight banks rather than every few minutes, so expect gaps of at least an hour between departures in the middle of the day. Early morning and late evening departures are fewer, so if your flight lands after 20:00 you should check that the last bus to your town of choice still runs that day.
The stop layout at Marseille Provence is simple: long-distance coaches for Manosque and beyond usually pull into the bays signposted for interurban lines in front of Hall A and Hall B of Terminal 1. The walk from arrivals in T1 to the bus stands is about 3–5 minutes with a rollaboard, and if you land in T2 you add another 5 minutes on foot to reach the same coach park.
These regional buses are standard single- or double-axle coaches with underfloor luggage holds, so full-size checked bags go underneath and only small backpacks or laptop bags stay with you in the cabin. Drivers normally open the holds a few minutes before departure, and boarding often closes right on time, so being at the stand at least 10 minutes before the printed departure time helps avoid a missed departure.
Practical tip: before you fly, screenshot the timetable for your exact segment (for example, Airport–Manosque or Airport–Gap) and keep it in your phone photos, because mobile data at the curb can be spotty when several planes land at once.
