The Francofolies de Spa is a major annual music festival held every July in the town, celebrating French-language music from across the world — Belgian, French, Canadian Québécois, African, and other Francophone artists all appear. It runs for several days and attracts international acts alongside emerging artists.
The festival is one of the main reasons to visit Spa in summer. The main stages are set up in the town centre, and the combination of the Ardennes setting, the compact festival site, and the quality of the programme makes it one of the better music festivals in Belgium. If you're planning to visit Spa in July, check the dates and book accommodation well in advance.
