ABSTRACT
The paper aims to present a comparison of visitor behaviors and visitor spatial and temporal distribution in a mountain national park between the pre-Covid-19 period (2017–2019) and Covid-19 pandemic year (2020). The research is based on pyroelectric sensor data from 2017–2020 and a survey of visitors designed to assess the spatial and temporal distribution of visitors and their behaviors and changes therein. The research data were used to identify two visitor clusters: Impact of Covid-19 (IC) and No-Impact of Covid-19 (N-IC). The research was conducted in Stolowe Mountains National Park (SMNP) in Poland using data from Monitoring System of tourist traffic (MSTT). A total of 374 respondents participated in the survey in 2020 period, which demonstrated a significant impact of the ongoing pandemic on many aspects of their behavior. These results were compared with the results obtained from 2,642 surveys carried out in 2017–2019. The findings are compared to findings reported by other authors. Some visitors did claim that the pandemic has not affected their behavior in any way.
