The Save (or Sabi) is a 400 km river of southeastern Africa, flowing through Zimbabwe and Mozambique. The river has its source in Zimbabwe, some 80 km south of Harare, then flows south and then east, from the Zimbabwean highveld to its confluence with the Odzi River. It then turns south, drops over the Chivirira (“Place of Boiling”) Falls, and flows down the western side of Zimbabwe's Eastern Highlands forming a dry river valley in the rain shadow of these mountains. It is joined by the Runde River or Lundi at the Mozambique border, forming a dramatic confluence at Mahenya.
