Tourism can be seen as all activities related to the journey and stay of a person outside his usual environment. Tourism delves into all spheres of economic and social development and is deeply incorporated in the flows of everyday life. When we look at the historical side, there were two key periods in our region: the period of world wars from the first half of the last century and the period of independence of the Republic of Croatia as the most important historical milestones for tourism. The structure of tourism organization is divided into state, social, economic, vocational and international levels. State bodies and institutions operate at the state level, the Croatian Parliament, the Government of the Republic of Croatia, is concerned, but the Ministry of Tourism as the supreme body of the state administration for tourism has the main role to play in determining the tourism development strategy of the country and carrying out professional and administrative tasks. At the social level, we mean tourist communities whose purpose is to establish the promotion of Croatian tourism. At the social level, we have both emitting and receptive organizations. Emitives include different societies, such as, for example,. bicycle companies, mountaineering companies and others. The receptive ones belong to society of friends of nature, cultural heritage etc.. Economic chambers, such as the Croatian Chamber of Commerce, the Croatian Chamber of Trades and Crafts, as well as professional associations such as the National Association of Small Family Hotels, Employers' Associations and Croatian Travel Agencies Association. At the level of international organizations there are numerous world (UN), regional (EU) and international tourist organizations (World Tourism Organization, Asian-Pacific Tourist Association and others. ) The joint activities of organizations at these levels, as well as the clear vision of tourism development in the future, will undoubtedly keep Croatia at the very top of tourist destinations in the world
