The Cango Caves in Oudtshoorn have been closed for the day, as a safety precaution following an earth tremor in the district.
EWN received several calls from residents who felt the tremor this morning, which came from a remote part of the Swartberger region.
The Council of Geoscience earlier confirmed a 3.5 magnitude tremor had struck just after 8am.
EWN's Natalie Malgas reports that there was no one in the caves at the time of the tremor, as it had not yet opened for business.
Disaster Risk Management says no injuries or damaged property have been reported at this stage, explains Malgas.
