||Thanks to its varied natural and artificial values the Duna-Ipoly National Park (DINP), established as the ninth national park in Hungary is suitable for numerous tourist activities (touring, cycling, horse riding, winter sports, water sports, caving tours, cliff-climbing, flying, fishing, hunting, etc.). Resulting from this, the employees of the national park must reckon with numerous unfavourable environmental effects produced by the tourism and increased by the closeness to Budapest. All of this is intensified on one hand by part of the territory being identical with the outstanding recreation district of the Danube Bend, on the other hand by its coming within the capital city’s recreation zone, due to which establishing the section of visitors is also problematic. Although attempts are made to demonstrate the values in the national park in the interest of avoiding the hazards and developing environmental awareness and ethics, regulation of the visitors’ activities, for the main part, does not take place in a planned manner. In our article, besides disclosing the causes of the disorganisation, we also stipulated the most important principles for solving these problems.
