Arandun is located on the far northern coast of Isilia, southwest of the Icelock Plateau. It is bordered to the west by Merredin Bay and is situated upon the banks of the Eosa River. It is surrounded by evergreen pine forests. Due to the cold climate, crops are nearly impossible to grow, so most of the nearby farmland is in the form of cattle and other stock.
Due to it’s far northern latitude, Arandun endures a cold climate with heavy snows during the winter.
