The Descente des alpages, an autumn event in Grenoble, France, is returning after a two-year break, taking place on Friday, October 9, and Saturday, October 10, in the city center. The event began in 2010 after a meeting between Bernard Mure-Ravaud, a Meilleur Ouvrier de France and world champion cheesemaker, and Chris Moiroud, a cattle breeding enthusiast. It aims to celebrate the local economy of the surrounding mountains, emphasizing craftsmanship and regional products. The event was not held in 2024 and 2025 due to a disease called nodular dermatosis, which affected cattle in the area. The program includes a parade of cows, raclette tastings, and science-related activities. A world record attempt for the longest pâté en croûte—a type of French pastry filled with meat—is planned, and a Franco-Swiss delegation will attend, accompanied by a raclette ambassador. This ambassador will organize a competition celebrating the best Alpine cheese traditions. Researchers from the University of Grenoble-Alpes, the CNRS (French National Center for Scientific Research), and their partners will also participate in the Fête de la science, engaging with the public and sharing their work. The event begins on Friday evening with an organ concert at the Basilica of Saint-Joseph in Grenoble, from 7 to 8 p.m. On Saturday, activities will be spread across several locations, including Etoile, Vaucanson, and Metz squares, Dr-Martin square, and Strasbourg and Lesdiguières streets. From 9 a.m. to 6 p.m., a village of local products will offer gastronomic stands, with more than 100 exhibitors expected to participate. Around 10 a.m., the cow parade will take place, with the animals starting from Robert-Schuman square and moving through the city to reach Vaucanson square. At 4:30 p.m., the public can watch the milking of the cows and their blessing in front of the Basilica of Saint-Joseph, offering an opportunity to meet farmers and learn about different Alpine goat breeds. According to the organizers, the event attracts between 10,000 and 30,000 visitors each year.
