The study analysed the problem of overtourism in Szklarska Poreba and the Karkonosze Mts National Park [KNP] (Poland, Lower Silesia voivodeship), i.e. the protected area directly associated with the city and municipality of Szklarska Poreba. The aim of the study was 1.to determine whether the phenomenon of overtourism occurs in this area and 2. what is its intensity. Statistical data of the Central Statistical Office (CSO), statistical data collected by KNP and the Municipal Office in Szklarska Poręba regarding the number of inhabitants, number of tourists, number of beds, number of tickets sold to KNP facilities in 2010-2022 were analysed. The study used chamber methods (analysis of literature and acquired statistical data) and field methods (field inspection, field verification of source data, execution and analysis of field documentation). Data made available by the administration of the Karkonosze Mts National Park, the Municipal Office in Szklarska Poreba and the management of the Sudety Lift sp. z o.o. cable car in Szklarska Poreba were used. The data collected included: - number of Karkonosze Mts National Park entrance tickets sold at the toll booths; - number of nights spent in Szklarska Poreba; - number of tourists using the tourist information office; - the number of passengers using the cableway, separately in the summer and winter seasons. As a result of the analysis, solutions were proposed in two categories of efficiency, i.e. 1. to be implemented in the KMtsPN area; 2. to be implemented by local authorities in the Szklarska Poręba Municipality. These solutions will bring, especially the areas of the commune, closer to acceptable conditions for ecosystem services and sustainable development.
