Firefighters have been battling a large vegetation fire near the Jonkershoek Valley outside Stellenbosch which broke out on Saturday night.
Cape Winelands Fire and Rescue Service's Jaco Thuynsma says an investigation is underway to determine the cause of the fire.
A helicopter, ground crews and volunteers have been assisting to fight the blaze since the weekend.
According to Thuynsma, the wildfire has caused damage to approximately 1 200 hectares of fynbos and other vegetation.
He says firefighters managed to steer the fires away from wine farms and other estates, and have contained the fire line breaking on the Jonkershoek side.
120 personnel in total are currently deployed to the mountain slopes and a helicopter remains on standby.
He says that no damage to human life, livestock or property has been reported.
Rainfall is expected on Tuesday and may provide some relief.
