The Doiran Memorial stands near Doiran Military Cemetery, which is situated in the north of Greece close to the Yugoslav frontier and near the south-east shore of Lake Doiran. It is approximately 2 kilometres behind the village of Doiran and is reached via a farm track after turning left in the village by a large taverna. The Memorial stands on what was called Colonial Hill, and can be seen from a distance and is a landmark.
