Tourism is the leading economic sector of the Republic of Croatia, and therefore it is important to continuously invest in tourism in order to provide better offer and quality in this branch. This is also a way to deal with seasonality in tourism which is a big issue. Croatia has a rich culture and history, pleasant climate, beautiful nature and Adriatic Sea and many other advantages through which it can develop a competitive tourism product. Primarily, it is necessary to overcome basing the offer in tourism exclusively on sun and sea but we need to focus more on developing other types of tourism products also. Istria is our main region in tourism, the most successful one, because she continuously invests in tourism, starting with investments in human resources, in different types of tourism products, in marketing and promotion, branding, in hotel industry and so on. Other regions in Croatia should follow her example in order to become more competitive on the market.
