The '''east''' consists of a large plateau with an altitude of 1000 1,000 to 2000 2,000 metres. It is largely covered by sclerophyllous plants and grassland. The plateau is cut by numerous varyingly deep canyons with more or less permanent streams. The east of this plateau is dominated by rocky cliffs, characteristic for Isalo.

The '''west''' is a vast [http://en.wikipedia.org/wiki/Monocline monocline] plateau with an average altitude of 1000 1,000 metres. It is almost entirely covered by sclerophyllous plants and large plains of grassland. In several places the plateau is cut by canyons, similar to those in the east. Like the east plateau, also the west plateau also ends by rocky cliffs.

The '''north''' consists of a large rock barrier in the eastern part with typical rocky escarpment at its end, varying in altitude between 800 and 1200 1,200 metres. The centre is formed by a vast monocline plateau, about 600 to 700 metres above sea level, which greatly reduces the lowering to the Amboloando river. The eastern part is a low plateau of 600 to 700 metres above sea level, descanting descenting to the Malio river.

The '''area surrounding the park''' in the west, east and south consists of peneplain with an average altitude of 800 metres. (A peneplain represents the final stage of fluvial erosion in times of extended tetonic tectonic stability.) In the west remains , some forest along the river beds of Malio, Analalava and Analambiaremains, forming the park boundary at this side. In the east, there is also a remnant forest along the river bed of the Menamaty, but smaller in size compared to the west. The rest is dominated by a large tree and shrub savanna which occupies a large area with grass land.<br>
