To the southwest, large inselbergs and tall hills separated by deep gullies predominate. The plateau gives way to the Cameroon coastal plain in escarpments.
This topography has resulted in the creation of the Lobé Falls near Kribi, where the Lobé River meets the sea in a series of rapids. Some of the plateau's highest points are in this region, such as Mbam Minkom near Yaoundé (1,295 m), and Ntem massif near Ebolowa (1,400 m).
