Follow signs for 'Marseille Vieux Porte', and go through the tunnel under the Vieux Port.
At the exit of the tunnel ensure you are in the left hand lane, to turn into the Tunnel
Prado-Carenage, signposted Aubagne. This is a toll tunnel.
At the exit of the tunnel, immediately after the tolls, turn right, taking care to be in the far
right hand lane. Ignoring the turn to the right, continue up to a roundabout, and follow signs
to ???, take the second exit.
Stay in the right hand lane and follow the road to a t-junction and a set of traffic lights.
Turn right at the lights, passing under some railway bridges.
Immediately after this, take the fly over, still keeping in the right hand lane up the flyover and
follow the lane to turn right.
Going straight over a set of major traffic lights, you will arrive at a roundabout. Turn left
onto Boulevard Michelet.
Follow this road straight, passing through multiple sets of traffic lights, until a roundabout is
reached containing the Obelisk de Prado. Go straight around this roundabout. Note: you do have
priority on joining, it does not work as an English roundabout!
Continue straight, passing through multiple sets of lights, until a further roundabout is reached.
Take the first exit, signposted Luminy. Follow this road to the next roundabout, taking the second
exit. Then about 0.5km, on the left, you will see the gates of the university campus, take this
entrance, and continue straight up the hill at the roundabout inside the gates.
Experian Prologia is about 0.5km up this road on the left
Take the metro line 2 to the station Rond-Point de Prado. Then take bus 21 or Jetbus 21 to the end of the line, "Parc Technolique et Scientifique de Luminy".
