They should be all around the eastern portion of the spillway going into the north. There is a Savannah area just south of the forests and north of the Black Galleon where there are cliffs separating the north from the desert, this is where the elephants roam.
In the Savana, around Swagger Rock there are many elephants, tigers and rhinos.
