I am looking for advice on sand beach areas in Tuscany. We will be there for a few days the very end of April, so I know it's not exactly swimming weather, but to be able to stroll on a lovely sand beach on the Mediterranean would be great. (I am going to be in the CT just before.) I have read that the northern Tuscany beaches around Viareggio are polluted and the southern ones around Grosseto are more pristine. Is that true? Is that more likely when it is tourist season rather than in April or is it the water that is polluted? Can anyone give me some suggestions? Thanks so much!
