Aix-en-Provence Travel Forum

will have 3 day stay in Aix without car. I know Avignon already. Whereelse I could visit for a half day each place outside Aix ( not Marseille )

there should be some good connections on the train to Avignon , I think it is direct, and Nimes, also direct. Arles is also a good place but requires a change. French railroad should supply the timetables.

the website is www.Sncf.fr

check for direction, hours, and prices here in French train official site for that region is here Provence.

nearby towns are Salon-en-Provence,Cavaillon (in the Luberon region) Istres,a bit further away is Arles,Tarascon, Martigues.
The best is the region of Luberon,north of Aix-en-Provence lovely country there.Manosque is another there in the Luberon.

they have an excellent bus service in the area, local and inter city nearby

No doubt for me: Cassis a the right choice for on half day ... See my answer to your other post
