The river rises on the eastern slopes of the Hope Range at heights of around 1200 metres. It flows East then south before joining the Buller River near Kawatiri Railway Station. A tributary called the Little Hope River rises near the Hope Saddle and flows southwest, joining the Hope River at Glenhope.
