Although smaller than the Koolau Mtns
, this range also runs north-south in the northwestern section of Oahu Island
. It divides the Waianae Coast from the Leilehua Plateau of the interior, which is still covered in sugarcane and pineapple.
The plateau runs between the two mountain ranges from Waialua - Oahu on the north shore to Ewa, just west of Pearl Harbor.
