The Lebombo Mountains, also called Lubombo Mountains (Portuguese: Montes Libombos), are an 800 km-long (500 mi), narrow range of mountains in Southern Africa. They stretch from Hluhluwe in KwaZulu-Natal in the south to Punda Maria in the Limpopo Province in South Africa in the north. Parts of the mountain range are also found in Mozambique and Eswatini.
Description

Geologically, the range is considered a monocline; part of a rifted volcanic margin.[1] The Lebombo monocline was aligned with the Explora Escarpment off-shore Dronning Maud Land, Antarctica, before the break-up of Gondwana.[2] The Lebombo monocline strikes N-S and dips to the east. It is composed of a sequence of Jurassic age volcanic rock, both basaltic lavas and rhyolitic flows and tuffs. The sequence rests on essentially horizontal Karoo Supergroup sedimentary rocks of the Kalahari Craton to the west and is overlain by Cretaceous to recent sediments to the east. The alternating resistant rhyolite and easily eroded basalts produce a series of parallel sharp cuesta ridges separated by savanna plains.[3]
The range is relatively low with heights between 400 m (1,300 ft) and less than 800 m (2,600 ft). The highest peak is the 776 m-high (2,546 ft) Mount Mananga. The 480 m-high (1,570 ft) Longwe is the highest point in the Lebombo Range north of the Letaba River.[4]
The mountains dominate Lubombo District in Eswatini. Towns in the area include Siteki in the centre, Lubhuku in the west and Mayaluka and Big Bend in the south with the Lusutfu River running past the southern region of the mountain range. At the north lie the towns of Simunye, Tambankulu and Namaacha, and the Mlawula Nature Reserve as well as the Mbuluzi River.
A number of rivers, including the Pongola, Mkuze, and Lusutfu, cross the mountains from west to east.
The name of the mountains is derived from the Tsonga clan of Lebombo or Rivombo that first settled the area, it can be linked to Limpopo river, where the Rivombo people also settled. Lebombo/Libombo/Rivombo is still used by Tsonga people as a surname.
Protected areas
