Six people died and nine were injured when the taxi in which they were travelling overturned on the road between White River and Sabie in Mpumalanga on Saturday night.
The passengers, from KaBokweni, outside White River, were returning from a tour of the Mac Mac waterfalls and other tourist attractions in the Sabie area.
Constable Gerald Sedibe of the White River police said the driver lost control of the vehicle in a curve and it overturned.
Four passengers and the driver died on the scene and one died on the way to hospital. The injured are being treated in hospital.
Sedibe said the exact cause of the accident could only be determined by investigations.
The Mpumalanga Department of Local Government and Housing has warned road users to be careful because roads are wet and in some areas there have been rocks falling on to roads because of rain.
