Rijeka (RJK) and the surrounding region have some interesting features to offer. The Croatian port city offers holidaymakers not only a variety of great sights, but is also close to Kvarner Bay. It is worth hiring a car for this reason alone, as well as to explore the surrounding region. Whereas the city itself can be explored on foot or by bicycle, the routes to the various monuments and historical buildings in the surrounding area are sometimes quite lengthy. A total of 17 city buses take holidaymakers to the individual sights in comfort. Rijeka (RJK) is particularly popular with holidaymakers interested in culture, with its numerous old buildings and walls displaying the cityâs long history, steeped in tradition. Rijeka (RJK) is also an excellent destination to spend an entire holiday on â or at least pay a visit to â the island of Krk. Located in the Kvarner Bay, south-east of Rijeka (RJK), Krk is the largest island in Croatia and is very easy to reach by car from the mainland via the Krk bridge near Kraljevica.
