A walker was rescued by helicopter after being cut-off by the tide on Holkham beach.
The alarm was raised just after 7.30pm last Wednesday and Wells RNLI volunteers and the Coastguard went to the scene.
Wells inshore lifeboat was on exercise in the harbour and the all-weather lifeboat was exercising in Holkham Bay at the time.
The person was on the high sands on Holkham beach.
A RNLI spokesman said the onshore sea and swell conditions made it very difficult to help the person from the seaward side.
The walker was not in immediate danger because it was high tide and they were left in the care of the local Coastguard team to be rescued from the shore.
“At 9pm the Coastguard helicopter was tasked to the incident. It winched the casualty to safety at 9.45pm,” the spokesman said.
