Water is the essence of Kvarner, and the region's largest city expresses this simply. Whether in Croatian or Italian (Fiume) the translation of the name to English is the same: river. Although the history of Croatia's third city goes back to the days of Imperial Rome, modern Rijeka evolved under the rule of Austria-Hungary. The historic core retains vestiges of the old Habsburg monarchy from the time when Rijeka served as the empire's outlet to the Adriatic. During the 1960s, under Yugoslavia, the suburbs expanded rapidly. Rijeka is the country's largest port, with a huge shipyard, massive dry-dock facilities, refineries, and other heavy industries offering large-scale employment. Since the breakup of Yugoslavia, however, Rijeka's role as a shipping town has declined significantly.
At the city's core sits Korzo, a pedestrian street of shops and cafés running parallel with the harbor and just to the south of where the land begins to rise toward the peaks of the mountains that back the bay. The high ground ensures that the suburbs stretch out to the east and the west, with little space to expand to the north. The general rule is that Rijeka is more of a transit town than a holiday destination, and it's not known for its points of interest, apart from the hilltop fortress of Trsat. However, the city is well worth investigating more thoroughly than most would have you believe.
Many visitors stay in the nearby seaside resort of Opatija, and locals will often head that way in their free time as well. That said, Rijeka is a perfectly pleasant small city (approximately 130,000 people call it home); if it did not command the wonderful bay that it does, it would also be unremarkable. This makes it one of the more authentically Croatian spots in the region in summer. Those looking to avoid the hordes could do much worse than to stay in Rijeka—albeit with very few options for accommodation—and use the excellent network of ferries to explore the rest of Kvarner.
Rijeka is the home port of Jadrolinija, the coast's major ferry company. Local ferries connect with all the Kvarner islands and will take you farther afield as well.
