School sports trips, as a part of extracurricular physical education (PE), are a very important addition to regular PE, with benefits for not only physical activity behavior, but also for personal development and social inclusion. To better understand the relevance for students, the aim of this study was to look at their perspectives on school sports trips in terms of involvement, active participation, and co-designing opportunities. Therefore, 14 group interviews with 47 students (age: M = 13.9; SD = 0.9 years) were held in three exemplary secondary schools in Austria. The following six topics were derived from a qualitative text analysis: (a) the relevance for the students, (b) the motives for (non-) participation, (c) positive experiences, (d) barriers and challenges, (e) desired changes and ideas of the students, and (f) feedback opportunities. The results indicate that students are highly motivated to put forward their ideas for designing school sports trips in terms of physical activity and social components. This can further be considered for the planning and implementation of extracurricular PE, to make this an enjoyable experience for both students and teachers, promoting the relevance of physical activity in schools and beyond.
