Marcus Cent's connection to Slovenia goes back further than most — he first came to Piran as an unborn baby, and it's stayed a special place for him ever since. He writes VisitSlovenia.com's guides from that long familiarity, and he'll happily argue Piran is one of the very best places anywhere for summer sea swimming: easily accessible, and gloriously refreshing once you're in.
