Oahu is called “The Gathering Place” for a reason. It’s the third largest island, but home to the vast majority of the state’s population. In fact, the population of Oahu is 950,000, and the state’s population is 1.3 million.l
Part of the magic of Oahu is the dichotomy between the ancient and the modern—the island is home to numerous historical sites, buildings, and areas, but Oahu is also where you’ll find Honolulu, a modern city teeming with skyscrapers and brimming with innovation.
Oahu is separated into five main areas: Honolulu, the North Shore, the Windward Coast, Central Oahu, and the Leeward Coast. Note that world-famous Waikiki is actually a neighborhood located in greater Honolulu.
Oahu occupies 597 square miles and is the second oldest of the six Islands of Aloha, lying between Kauai and Maui. Oahu is made up of two major mountain ranges that were once shield volcanoes that are now extinct. These two mountain ranges—the Waianae range to the west and Koolau range to the east—run almost parallel to each other.
The Waianae range on the west side, separates Central Oahu from the Leeward Coast. For the most part, the leeward (west) side is considerably warmer and drier than the east.
The Koolau mountain range spans the length of the island’s eastern coast for about 34 miles from Kahuku in the north to Makapuu in the south. The Koolau range separates the Windward Coast of Oahu from Central Oahu. Today, the Windward Coast tends to be Oahu’s wetter and greener side of the island.
