There are various routes to the summit, the easiest (also steepest) being up the Ga'aseb river valley, but other routes include the Hungurob and Tsisab river valleys. The nearest settlement is Uis, roughly 30 km from the mountain. The core area of was declared a National Monument in 1951.


Origin of name

The name ''Brandberg'' is Afrikaans, Dutch and German for ''Burning Mountain'', which comes from its glowing color which is sometimes seen in the setting sun. The Damara name for the mountain is ''Dâures'', which means 'burning mountain', while the Herero name, ''Omukuruvaro'' means 'mountain of the Gods'.

Flora of Namibia

The Brandberg lies within the Karroo-Namib floristic region and few members of the Cape flora are represented.A checklist
of 357 species was published in 1974 by Bertil Nordenstam stating that 11 taxa are endemic to the Brandberg, with a further 28 species endemic to the Kaoko element. A large and significant group of species has a disjunction between the Karroo-Namib region in the south, and the arid parts of north-east Africa. These appear to be remnants of a hypothesised arid-track joining the two areas.


Noteworthy species

*'' Aloidendron dichotomum'' is the largest and arguably the most conspicuous succulent on the mountain exceeding 5m height. It is infrequently encountered, mainly on the upper southern slopes. *'' Cyphostemma currorii'' is another large succulent of the grape family that is scattered across the mountain. *''
Myrothamnus flabellifolius ''Myrothamnus flabellifolius'' is a plant species in the genus ''Myrothamnus ''Myrothamnus'' is a genus of flowering plants, consisting of two species of small xerophytic shrubs, in the southern parts of tropical Africa and in Madagascar. '' ...
'' is the resurrection plant. It is common on some of the upper slopes, and can be made into a tea. * ''Olea europaea'' subsp. ''africana''. Not normally associated with such arid regions, this is only known from the peak of Konigstein.


Brandberg endemics

*''Euphorbia monteiroi'' subsp. ''brandbergensis'' is a toxic upright succulent found in the upper altitudes. It is occasionally browsed, presumably by dassies (rock hyraxes). *''Plumbago wissii'' has pink flowers. *''Hermannia merxmuelleri'' was previously only known from Tsisab valley, and is unusual within the genus in having a crested capsule much like the American species of ''Hermannia'' and ''Hermannia cristata'' from the summer-rainfall region of South Africa. *''Othonna brandbergensis'' discovered by B. Nordenstam on 29 May 1963. *''Hoodia montana'' *''Mentha wissii'' *''Ruellia brandbergensis'' *''Felicia gunellii'' *''Nidorella nordenstamii'' *''Pentzia tomentosa'' *''Scirpus aciformis'' *''Scirpus hystricoides''
