Can anyone confirm if a US passport and Visa are needed to travel from Zagreb to Ljubljana via the bus as indicated on the ticket?
We will be on our own not with the tour group.
I thought with Croatia’s entrance into the Schengen zone that was eliminated. But I could be wrong. US citizens do not need a visa for either country. That ended with the war.
Yes, you are crossing an international border so you need a passport. But no visa needed for US citizens.
