Tourism as a phenomenon greatly affects the Croatian economy. However, in the internal part of Croatia, tourism is still not as developed as on the coast, but it has great potential for development. This paper presents tourist attractions and opportunities for the development of special interest tourism in the area of Kopački rit. Due to its unique environment, flora and fauna and potential opportunities for the development of special forms of tourism, natural resources and cultural heritage of Kopački rit attract a large number of diverse population. Kopački rit is one of the most important attractions in Osijek – Baranja County and thus contributes to the development of tourism, and attracts tourists who come primarily for its natural heritage. The analysis carried out within this paper indicates that additional contents related to special interest tourism can be developed in Kopački rit, such as hot air ballooning, a school for Little Guardians of Nature, making clay souvenirs or orientation in nature. The results of this work can help as a source of improvement of the existing and potential offer of Kopački rit.
