This final paper explores European Cultural Routes with a specific focus on the routes in Croatia and Istria. Cultural routes, which connect historical, social, and artistic components of specific regions, are developed within the Council of Europe's program aimed at promoting European history, identity, and sustainable development. The paper analyzes the significance of cultural tourism and the role of cultural routes in enriching tourist offerings, alleviating overcrowded destinations, and discovering lesser-known areas. Particular attention is given to cultural routes in Croatia, which offer diverse experiences and activities. In Istria, notable routes include the city of Labin, part of the ATRIUM cultural route, and Camino South Istria, a route aiming to become part of the European network of pilgrimage paths. The analysis also covers the Roman Emperors' Route, the Museum of Olive Oil in Istria, and Poreč’s membership in the Phoenician Routes. The paper further considers future expansion opportunities, such as the proposed "Bloomsday Route“.
