O’ahu Geographical

Oʻahu, the third-largest Hawaiian island, is a geographical masterpiece shaped by two ancient volcanic mountain ranges—the Waiʻanae Range to the west and the Koʻolau Range to the east. These lush, jagged ridges create a dramatic backdrop and divide the island into distinct regions: the vibrant South Shore, the lush Windward (East) Coast, the relaxed North Shore, and the sunny Leeward (West) side.

Oʻahu spans approximately 597 square miles and features over 125 beaches, fertile valleys, hidden waterfalls, and rich coral reef ecosystems. Its diverse landscape makes it easy to go from surfing world-class waves to hiking rainforests to relaxing on a secluded beach—all in one day.
