The Amathole Mountains form part of the southern portion of the Great Escarpment, rising over 1,800 metres above sea level. The escarpment slopes are densely covered in ancient forests of yellowwoods, white stinkwoods, Cape chestnuts and other indigenous trees. Deep indigenous woods like Kologha and Kubusie are some of the largest swaths of forest in South Africa. The mountains are capped with flower-rich montane grassland. Albany thickets also feature prominently in the surrounding area.
