The Firien wood or Halifirien Wood also called Firienholt, Whispering Wood, and Wood of Anwar is an oak forest below the Halifirien, the last of the Warning beacons of Gondor. It was located at the foot of the White Mountains bordering the Mering Stream and the Eastfold of Rohan in the land of Anórien. It was about twenty or twenty-five miles for west to east. The Great West Road passed through here in a long cutting within the forest done to avoid the wet lands that lie to its north.
