Tourism presents the term where a person makes a trip outside his own place of residence for a period of time longer than 24 hours, all for the purpose of rest, recreation, travel, work and the like. The sustainable development of tourism is extremely important so that future generations can enjoy the natural beauty as the present generation has the opportunity. With the help of the Sustainable Tourism Development Strategy until 2030, the Republic of Croatia has made a plan according to which it will try to meet the key challenges it faces. One of the biggest problems in the Republic of Croatia is poorly developed tourism in the continental area compared to areas near the Adriatic Sea. The goal of the final paper was to investigate the tourism economic valorization of Kopački rit. The analysis came to the conclusion that Kopački rit has all the predispositions for development and progress in tourism, but does not use them in the best possible way. Valorization is used to evaluate all terms that can be connected with tourism, and based on this, a SWOT analysis was made, where it is evident that within Kopački rit it is necessary to continue to encourage strengths, to use all the opportunities that come to fulfill the potential, to remove all weaknesses, and potential threats overcome.
