The summer 2024 pluridisciplinary field trip took 31 students from all scientific disciplines to the Pyrenean mountains, in South of France. It was the 3rd time that it was organized in this beautiful region, but it brought us new observations. This year, we had the opportunity to clearly observe several river otters in the river next to the hostel. The teachers present this year include Frédéric Silvestre, Johan Yans, Marie-Laurence Hubin, Jérémy Berthe, Pierre Devos, Fernande Friesing, Philippe Martin and Laura De Wandeleer.
