This article deals with the relationship between adults' free time and further education. More specifically, the paper addresses the question of whether there are similarities and analogies between the leisure time that adults dedicate to non-formal educational activities and free time per se. A structured questionnaire was used to examine the above issue. A total of 787 adults, who were involved in some kind of non-formal education in a region of Greece, replied to the questionnaire. The results of the research revealed that, despite the fact that all those who participated in non-formal education activities have limited free time, they prefer to dedicate some of it to learning opportunities. Furthermore, it seems that a connection between the particular learning programme and the participant's professional field is an essential factor in the choice of the programme. Conversely, personal needs and preferences, as well as individual flair, have less to do with this choice.
