Windward Oʻahu sits at the center of one of Hawaiʻi's turning points. In 1795 King Kamehameha I landed on the island and won the Battle of Nuʻuanu in the cliffs above Honolulu — the victory that brought Oʻahu under his rule and all but completed the unification of the Hawaiian Kingdom. In the century that followed, missionaries built churches and planters laid out farms along the windward coast, yet Kailua stayed rural and Hawaiian at heart: a district of taro, cattle, and fishing, far from the harbor town growing up on the leeward side at Honolulu.
Kailua's name means ‘two seas,’ for the two currents that meet across its broad windward bay, and people have lived along that bay for many centuries. Native Hawaiians settled the fertile lowland behind the beach, farming taro in the wetlands of Kawainui — the largest ancient marsh in the islands — and raising fish in walled coastal ponds. Above the marsh still stands Ulupo Heiau, a massive stone temple platform whose terraces were laid by hand long before Western contact and are preserved today as a state monument. This was rich, settled country: water, fishponds, taro, and a sheltered bay, all held in by the green wall of the Koʻolau Range that rises sharply behind the town. From the water it is an unmistakable place — a wide blue bay, a green ridge, and a low, fertile plain in between, the kind of setting that draws people and holds them.
Why People Visit Kailua
Kailua blends scenic windward beaches with deep Hawaiian heritage. Visitors come to swim, paddle out to the islands, and hike to a pillbox view, then slow down in a town that stayed local. It is picturesque, approachable, and meaningful to the island families who call it home — natural beauty and everyday culture side by side, with year-round appeal in its parks, paths, and shoreline.
