As a response to the intercultural challenges of Geography Education, this study seeks to determine factors fostering intercultural competence of student teachers. Based on a one-week multicultural field excursion of eight German and eight Turkish students in Kayseri (Turkey) on Education for Sustainable Development, we used qualitative interviews to evaluate changes in the 16 student teachers' intercultural competence. Findings strongly indicate that multicultural fieldwork fosters intercultural learning on a personal level.
