Crews of firefighters battled a forest fire off the A149 near Sandringham.
At least five fire engines and a water carrier were called to the incident just before 7.45am on Tuesday (August 9).
The blaze is believed to have started on Monday but when firefighters returned to look on Tuesday morning it was still smouldering.
Fire engines from Sandringham, King's Lynn North and King's Lynn South as well as a water carrier from Fakenham tackled the blaze.
A Norfolk Fire and Rescue Service spokesman confirmed crews used main and hose reel jets to extinguish the fire.
A drone was also used to check for hot spots.
Rob Curtis, station manager for King's Lynn North Fire and Rescue Service, said crews plan to return later in the day to check on it.
No other emergency services were called to the incident.
