Visit two famous Istrian towns to grasp the peninsula's amazing contrasts. Nestled at the foot of mount Učka, with stunning views of the nearby islands of Krk and Cres, Opatija is one of the regions' most famous resort towns. Once the favorite holiday spot of the Austro-Hungarian Emperor Franz Joseph, the Empire's touch is still evident along its famous seafront promenade. Just a short drive away, the urban Rijeka showcases an industrial feel and boasts one of Croatia's most active alternative scenes. Stroll around its lifeline, Korzo, then head up to Trsat Castle for panoramic views from its vantage point on a 138-meters-tall rock.
