For many students, excursions and field trips are among the most enjoyable and memorable parts of their studies. Some may even have chosen to study geography because of that—or at least the option to be outside was a strong argument to choose this subject. For us as teachers, excursions and field trips are equally special. They offer a chance to step outside the classroom, share our excitement in small groups, and show what we study in the real world.

But what happens when the roles are reversed? When (former) students invite us on an excursion? That’s when things become truly rewarding. It’s not just about seeing the newest equipment that they use for their work or hearing about their projects—it’s also about witnessing their confidence and independence, and seeing their enthusiasm for the things that they encountered for the first time during their studies and now use in their professional lives.

Meeting former students is always a pleasure, whether at conferences, summer schools, or at unexpected places, like a mountain hut or a soccer match (and yes, thank you for reminding us of your name and which course you took when you meet us at such unexpected places!). But being invited for an excursion and join their daily lives feels extra special. In that moment, the former student becomes the teacher, sharing their passion and expertise with us. These experiences remind us why we teach: not just to pass on knowledge, but also to inspire curiosity and confidence that lasts beyond graduation.

Former MSc student Elena Santi invited me on a short excursion across Irchel campus. As part of her work for Monitron AG, she monitors water levels, temperature, and nutrient concentrations in the various new ponds on campus.
