Factors of modern society, such as fast paced lifestyle, increasing influence of social media and technology on the life of individuals and unpredictable future have an impact on leisure time activities of children and the youth. Leisure time is the time that makes it possible for an individual to try diverse and various activities, it is the time at one's disposal. The way of how one spends leisure time is even more important in transition to adulthood, because in this transition they try new life styles and explore their personal restraints. Ways and possibilities for leisure time activities depend to a great extent on what their home town offers. The offer differs from town to town. My key question is what kind of possibilities for spending leisure time have children and adolescents in Municipality of Tolmin and if it would be reasonably to fill the offer up. With a group of colleagues, I am a member in the society called Mala Hiša. We offered children in aforementioned municipality an alternative for leisure time activities in the form of a centre for quality leisure time activities. It is a preventive program that aims to create the best conditions for the development of children and youth through the use of quality time. The empirical part of Master’s thesis deals with ways and forms of the systemic arrangement of centre for children and adolescents in the Municipality of Tolmin through opinions of children, adolescents and experts on the field of working with children and the youth.
