The currency in Poreč is the euro (EUR).
That means you no longer need to take Croatian Kuna. (If you have any left from previous trips, leave them at home – the kuna hasn’t been legal tender since euros were introduced in January 2023).
It’s a good idea to exchange your pounds for euros before you go on holiday, to take the hassle out of sorting it when you arrive in Poreč, or to avoid high rates at the airport. Ordering your currency online is quick and easy! Travel money cards are a really handy option, too – simply load them up with euros and use them like a debit card.
