My daughter is in Paris for a month taking a language course. She has a friend there and they both are looking at a long weekend somewhere where there is a nice beach and sunny weather. They want to take the train from Paris. I realize this is the Paris forum but since we don't know their destination I thought I would look for advice here. Nice, Biarritz? Are there beaches in Nice that are not rocky? They would be going down on a Wednesday and coming back to Paris on a Sunday. They are both 21 are well traveled. Any suggestions are welcome!
