Ouagadougou draws large numbers of visitors to the biennial Pan-African Film Festival. The International Crafts Fair, which is held in alternate years, celebrates the valuable and various craft production of the nation's artisans. Several daily newspapers are published, including the government-sponsored Sidwaya, as well as a number of weeklies. There are three national parks those of Po, Arly, and in the east, straddling the border with Benin and Niger, the great "W" National Park. Folklore is valuable, reflecting the nation's ethnic variety. On national occasions each region is described in the capital by its own folkloric group.
