Trsat Castle is one of the best-preserved medieval castles of the Adriatic, with its bulk still intact, and towers which touch the sky.
By bus, climb the hill upon which it towers: it's only 138 meters high, but from up here, the old town and the entire Kvarner Bay are at your feet. Your phone battery is fully charged, right? Photos from up here are a must!
With your guide, you'll pass through its mighty walls, which are home to a collection of modern art, and discover all the secrets of the castle, built in the 13th century and restored by an Irish count in the 19th century.
Then go down into Rijeka and walk along the Korso, the city's famous pedestrian boulevard, past the colorful old buildings and Baroque churches: the one with the round floor plan is Rijeka Cathedral, while the 538 stone steps lead you to the Church of Mary of God of Trsat, the oldest church in Croatia.
In your free time, get a few more shots of the town hall and the municipal tower, and wander around Rijeka's many galleries in search of a worthy souvenir of your day: from hand-painted ceramics and paintings, you'll be spoilt for choice!
