The geological shape of South Africa can be described simply as an interior highland surrounded in the west, east and south by escarpments. The mountain range of the Drakensberg is part of the eastern escarpment, reaching heights of almost 3500 metres. The highest mountain is the Thaba Ntlenyana peak (3482 m) in Lesotho.
The "Dragon Mountains", as the Boers called them, were not shaped by tectonic uplift but rather through erosion. The mountain base had originally been part of the supercontinent Gondwanaland, which broke apart about 300 to 100 million years ago to form the new continents. The continental drift that went on over millions of years was accompanied by arching, faulting, rifting, and extensive volcanism.
The land of today's KwaZulu Natal used to be covered with up to 1,000 metre thick layers of lava. When this mass solidified, the heavy granite stone pressed onto the layers of sandstone beneath. Due to the high relief and associated steep gradients to the Indian Ocean, significant erosion occurred. Alluvial streams and rivers deposited rubble at the base of the escarpments and carried away finer materials. Through millions of years of constant erosion, the rugged steep slopes of the Drakensberg were shaped.
The UNESCO declared the Drakensberg in the year 2000 a World Heritage Site. The new uKhahlamba-Drakensberg Park protects the 200 kilometre long and between 10 and 25 km wide alpine mountain world of breathtaking beauty. The park comprises a total of 236,000 hectares, starting in the north with the Royal Natal National Park and reaching down to the Drakensberg Garden Castle the south. One can't travel the park in its length form north to south or south to north. Instead, there are several roads leading from towns in the foothills up to the resorts and nature reserves in the mountains. So it takes a couple of days to experience all parts of the Drakensberg mountain world.
