National currency in Croatia is Kuna (HRK). Although EUR can be accepted in some establishments please keep in mind that Kuna is in most cases the only mean of payment accepted. ATM machines can be found almost everywhere and therefore you do not have to worry for cash withdrawals if you get to the point that you ran out of Kunas.
La moneta nazionale in Croazia e' kuna (HRK). Nonostante che` alcuni posti possono accetare gli Euri nota per favore che HRK e' unica moneta ufficiale. I cash bancomati sono quasi ovunque cosi non si deve preocupare se Le viene mancare la moneta nazionale per i pagamenti.
