With some terrific day trip options available in the surrounding area, renting a car makes good sense. Without one, it’d be much harder to soak up all that Rijeka, 18 miles away, has to offer. Soak up the sights starting with Rijeka Ferry Port, Rijeka City Museum and St. Vitus Cathedral. The locals are also likely to point you toward Opatija, 20 miles away. If you can only see one thing here, make sure it’s Slatina Beach. (But we’d also recommend Lido Beach and Medveja Beach.)
