The festival's programme is broad and combines theatrical events, music concerts, video projections, dance performances, and even afternoon shows for children. Attendance is free of charge. Since its beginning in 1992 the main criteria for inclusion in its programme has been variety, humorous content and a degree of summertime levity. Gradually Trnfest Festival has transformed itself into a sociable, easy going gathering, end of summer festivity with the programme withdrawn into the secondary plan. In spite of this newly found functionality, Trnfest still occasionally presents some fine music and artistic performances at a time when the Ljubljana cultural offering also goes on summer break.
