The aim of the research is to explore the relationships between the different forms of active tourism and the service needs that arise, and the role of the use of information sources in the decision-making of active tourism participants. The closed-ended questionnaire survey investigated respondents' hiking habits, the services they use and the sources of information on active tourism. The questionnaire was completed by 169 people who had hiked in the Lake Velence area, their responses were analysed using SPSS and Excel programs. Cluster analysis was used to ide ntify different groups of active tourism participants, depending on the type of tours they prefer, the services they use and the sources of information they r ely on. ANOVA (one-way analysis of variance) was used to test whether different types of active tourism influence the use of services and to identify which services are most important for each group. In addition, a Pearson correlation matrix was constructed to show the relationships between each of the quantitative variables. The research contributes t o a better understanding of how different forms of active tourism and different information sources shape the service needs of active tourism participants, which can help to target the development of tourism services and the transition to the circular tour ism.
