The aim of this paper is to quantify tourists (both domestic and international) of Slovakia and their chronology throughout the years. Firstly, a brief development of them is introduced (absolute number and proportion of the total traffic from 1985 to 2013). Subsequently, the structure of their nationality, spatial differentiation (at municipal level) and seasonality is discussed (respective distribution during the year). The aim of this study is to discover a spatial context in space and time. To quantify the number of tourists, the data from the Statistical Office of the Slovak Republic and also from the Ministry of Transport, Construction and Regional Development, are used. These data are interpreted in analyses and confirmed by tables, graphs and pictures.
