The research has been undertaken to measure the maximum number of visitors Krka National Park can sustain daily without degrading natural resources and visitor experiences. Parameters considered in the measurement of the carrying capacity were the ones that limit the visitor use the most (the path network, eutrofication, noise). Carrying capacity of the protected area is the minimum environment’s capacity considering all the measured parameters. The results have shown that the number of tourists depends on the number of paths in Krka National Park, as well as on how long, connected or disconnected they are. The estimation of the maximum daily number of visitors to Krka Nationl Park is the following: the entrance Skradin – 2375 visitors, the entrance Lozovac – 775 visitors, the entrance Roški Slap – 8640 visitors. Total daily carrying capacity of the environment amounts to 11 790 visitors. This number can be reduced further by changing the managing system (by establishing a nature reserve within Krka National Park), as well as by the introduction of new parameters. Moreover, by reorganizing the infrastructure and extending the offer, the number of tourists could even be increased, which would lead to an increase in funding available for the protection of Krka National Park.
