Grünau is a settlement in the ǁKaras Region of southern Namibia, west of Karasburg. It is linked to the South African border posts near Noordoewer via the B1 and near Nakop via the B3. Grünau belongs to the Karasburg electoral constituency.[1]
A small desalination plant was built in 2020 to counter the poor quality of groundwater in the settlement.[2]
