Hi all: Hoping to get some suggestions for great day trips accessible by public transportation from Montpellier. I've got lots of time (here for 6 weeks) and want to see as much as possible of the surrounding area, without springing for a lot of overnight stays or car rentals. Today I went to Aigue-Mortes...fabulous. I know I can easily reach Nimes, Arles and Sete by train, and I'm hoping for some more suggestions, perhaps by bus? I don't mind spending an hour or two on the bus each way...I get to see the countryside, read and relax while en route. Just so long as there's a bus back at the end of the day and enough time in between to make it worthwhile.
And, if you were to pick one or two places for an overnight, what would they be? Carcassonne? Avignon? Something else? I'm mostly into history, architecture, scenery and charm.
Thanks!
