La Fête du Champ à l'Assiette ★ 4.3
The Fête du Champ à l'Assiette turns the old Prévalaye farm into a free three-day gathering of Ille-et-Vilaine producers, growers' markets and food talks.
Tip: Admission is free and the site is a working farm on the Vilaine towpath, so cycle out from the centre; the 10th edition ran 12 to 14 September 2025.
