I sea swim all year in Ireland, and am thinking of a trip to Italy at mid term where I could swim. By the sea obviously, but preferably also in a town or city. Naples would be my ideal this year. I have done this in Spain in November previously. Obviously the locals think I am bonkers but this does not bother me at all. Are there parts of Naples with swimmable beaches? I have never been. I would do normal tourist stuff too e.g day trip to Pompeii. Don't want to drive though. Any ideas? Open to other parts of Italy too though.
