The prominent geographical features of O‘ahu are two parallel mountain ranges: the older Wai‘anae Mountains and the deep-furrowed Ko‘olau Mountains. Formed by volcanic eruptions more than one million years ago, the two mountain ranges are aligned perpendicular to the northeast tradewinds, creating a wet windward side of O‘ahu (the eastern side) and a much drier leeward side.

The majestic Ko‘olau Mountains run north to south for the entire span of the island of O‘ahu. Between the two major mountain ranges is Leilehua Plateau, a fertile area known for its pineapple production.

O‘ahu has three prominent geologic landmarks known as tuff cones: Koko Head (Kohelepelepe), Punchbowl (Pūowaina), and Diamond Head (Lē‘ahi). These volcanic cones provide visual reminders of the island’s volcanic past. O‘ahu has 62 county parks as well as 25 state parks and three national parks.
