Brittany doesn't run short of festivals and events for the weekend of August 8-9, 2026 (8-9/08): ten days of fest-noz wrap up in Lorient just as a dozen other events kick off across the region's four departments. Our pick goes to the Interceltic Festival's grand finale, but the lineup also covers a nocturnal sound-and-light show, an electro peninsula and a horse fair founded in 1936 near Loudéac. Between a Celtic mega-gathering, island opera and countryside fest-noz, this weekend in Brittany won't leave you bored. Stade du Moustoir or the open-air galleries of La Gacilly — where do you start?
