Access to Cassis with a coach: what you should know
As Cassis is a very attractive place of interest, access by bus is regulated.
In high season (May 1 – Sept 30), buses are not allowed to enter Cassis. They must park at the entrance of the town, at the parking lot called Parking des Gorguettes. From there, passengers have to take a paid tourist train to go to the heart of the village (you have to book the tourist train in advance. Have a look here.
In low season (Oct 1 – April 30), buses can only drop off and pick up at the bus stop called “Gendarmerie”. People then have to walk to the center of Cassis. Have a look here.
