The northern half of the nation is generally characterized as savanna--a large plateau consisting primarily of rolling hills, low-lying vegetation, and scattered trees. Vegetation varies from woodlands to grasslands and occasional patches of dry scrub in the far north. Some narrow strips of forest extend toward the north along watercourses and drainage lines. The southern portion of the savanna is sometimes referred to as the transition zone (zone de transition) and the northern portion as the sudanic zone (zone soudanienne), although the entire region is transitional between the narrow belt of forest paralleling the coastline and the Sahara Desert. The gently rolling plains are broken occasionally by granite domes or small hill masses, the most extensive being the Komonos Hills. In the northwest, a number of peaks exceeds 800 meters elevation.
A major divide extends across the northeastern corner of Côte d'Ivoire near Burkina Faso, separating the main southward drainage system from the Volta River Basin, which drains to the north. Near Bondoukou, where the divide crosses the Ghana border, Mt. Bowé de Kiendi reaches 725 meters elevation. In the north, Mt. Yélévé reaches an altitude of 685 meters.
