About Zagreb
Croatia's compact capital is a far less-visited alternative to the Adriatic coast, with a strong coffee culture, a medieval upper town, and a walkable centre that rewards slow exploration. Zagreb Airport (ZAG) has been growing with Ryanair and Eurowings connections, and Plitvice Lakes National Park - one of Central Europe's most spectacular natural sites - is a three-hour drive south.
