An integral and exciting part of a student's education at KLAS, these trips are conducted twice a year and are normally four or five days long.

Typical destinations for the spring European Cultural trips are Budapest, Berlin, Prague, Florence, Vienna, Barcelona and Lisbon. The fall Swiss Cultural trips for 10th and 11th graders offer destinations such as Zurich, Lugano, Neuchatel, Bern, Geneva and Lucerne. At the same time, seniors go on their own trip to Italy.

After all these trips, students are required to write a report, in English, describing what they have seen and learned and their impressions of their destination.

Every year, KLAS has so-called September Trips. In groups of about twenty, students leave campus for three days of adventure. These trips are based around outdoor pursuits such as rafting, trekking, skiing, horseback riding and cycling.

Every weekend of Term 1, KLAS organizes two excursions around Switzerland and to nearby countries, such as Italy, Germany and France. These excursions enable KLAS and visiting exchange students to spend time together at some of the most famous places in the region.

KLAS organizes optional trips over the spring and summer short breaks to European countries. Upon request, the school will arrange for homestays with either French-speaking or English-speaking families.
