You want to go to the Old Port
Go on foot
Just take the big stairs from the station down to Place des Marseillaises. Then straight on! Go down Boulevard d’Athènes, Boulevard Dugommier, and you’re on the Canebière! Turn right and you’ll reach the Vieux Port at the end! If you decide to go straight ahead, you’ll reach the Cours Julien district via Boulevard Garibaldi.
Getting there by metro
Stay inside the station and go down to the 2nd basement level to metro line 1, direction La Fourragère, Vieux Port stop. You can choose to exit at the bottom of the Canebière or directly onto the Vieux Port platform! You can find all the information you need about public transport in Marseille on the RTM website.
