The NSRI has reported that a 30 year old woman has been missing since Monday after she fell from a cliff at The Point in Mossel Bay.
The woman is believed to have fallen into an area that is extremely difficult to access, NSRI spokesperson Craig Lambinon said in a statement.
Police, fire and rescue services and emergency medical services have conducted an extensive search in the surrounding area.
Some reports suggest that the woman might be living in the caves along the cliff face but officials have seen no sign of her, Lambinon said.
The investigation continues.
