The coastguard helicopter has been called to rescue a woman cut off by the tide at Holkham Beach.
Emergency services were called out on Wednesday evening, including the coastguard and Wells RNLI.
Coastguard received a 999 call from a woman at 7.30pm reporting she had been cut off by the tide.
A Maritime and Coastguard Agency spokesman said: "She is not in any immediate danger and the tide is going out. The helicopter is going to get her and bring her in."
Wells inshore and all weather lifeboats had been out on a training exercise when they were paged by the coastguard, with the inshore lifeboat tasked to attend to the woman.
The coastguard also paged Hunstanton Lifeboat to assist.
Initial discussions between services due to the water's conditions was to wait until the tide had ebbed for the woman to walk back to land safely.
A Wells RNLI spokesman said: "The inshore lifeboat went out to where the casualty is. She is not injured in anyway."
At 10.15pm the Maritime and Coastguard Agency confirmed the woman had been brought back to land by the coastguard rescue helicopter.
She required no medical attention.
A coastguard spokesman added: "Always check tide times before you go as it is so easy to be caught out. In an emergency at the coast call 999 and ask for the Coastguard."
