Croatia to Austria: what you need before you fly
Visa
No visa needed · up to 90 days
No visa: a valid passport or national ID card is enough. Stay up to 3 months without other formalities; for a longer stay, register with the local authorities. Between Schengen countries there are normally no ID checks; to or from Ireland or Cyprus you must show your passport or ID card at the border.
