Kvarner and the highlands

Why go

The gulf's islands, especially Rab and Lošinj, offer a different pace from the uplands of Gorski kotar, Velebit and Lika. Opatija adds a nineteenth-century resort story, while Risnjak and Plitvice Lakes point toward longer nature days. Treat the islands and mountains as distinct parts of the region when choosing a base.

What to look for

• Opatija's resort tradition dates to the nineteenth century.
• Rab's historic town and Lošinj's island setting contrast with the mainland mountains.
• Gorski kotar, Velebit and Lika bring forests and peaks into the itinerary.

Useful to know

• Choose an island stay for sea-focused days or an inland base for mountain and park visits.
• Give Plitvice Lakes its own substantial outing rather than treating it as a quick coastal stop.
