Highland Council engineers were inspecting the sea wall at Cromarty View yesterday following reports at the weekend that it had been damaged.
The Area Community Services team has confirmed that the void has been caused by sea erosion.
Local councillors have raised their concerns for public safety in relation to the pathway and measures are being put in place to cordon the area off to keep pedestrians away from the affected area of sea wall. Repairs to the affected area will get under way as soon as possible.
The council asks that people adhere to the cordons that are put in place for their own health and safety.
