Festival do Zambeze in Zambezi River towns
A river-themed festival concept spanning towns along Mozambique's stretch of the Zambezi, Africa's fourth-longest river and site of the major Cahora Bassa hydroelectric dam, though no independently confirmed recurring event under this exact name was located.
The Zambezi is not a minor waterway passing through Mozambique, it is the fourth-longest river in Africa and the continent's largest river flowing into the Indian Ocean, rising far away in Zambia and crossing through Angola, Namibia, Botswana, and Zimbabwe before finally claiming the entire width of Mozambique on its way to the sea.
