Campus Life

View of Campus

At International School Altdorf, students are instilled with a sense of responsibility, even when it comes to extracurricular activities.

Our students have access to a range of extracurricular resources on campus, including a student-run animal shelter and facilities for tennis and basketball. Our school is located at the base of the Swiss Alps and the beach of Lake Lucerne, so outdoor activities are part of everyday life as well. Students are free to create their own clubs and the range evolves from year to year. We believe extracurricular activities are an important part of students’ education and personal development. We encourage students to actively participate and challenge themselves outside of the classroom.
