Poliahu Heiau is an ancient Hawaiian place of worship in Wailua River State Park on Kauaʻi, near the Opaekaʻa Falls lookout. Its stone enclosures sit above the Wailua River, with views across the valley and, on clear days, toward the ocean. Informational signs introduce the site’s history, though its exact use is not known. Walk around the remains without climbing on the stones, and take time at the nearby viewpoints. Chickens roam the grounds, and picnic tables make this a possible short stop for a meal outdoors.
A sacred site above the Wailua River
Poliahu Heiau stands on a bluff in Wailua River State Park, near the Opaekaʻa Falls lookout. It is one of several heiau, or Hawaiian places of worship, associated with the Wailua River. The river’s banks hold deep cultural significance, and the stones here should be treated with care.
The site once covered more than an acre. Accounts describe stone walls about five feet high and five feet wide, enclosing an area roughly 165 feet across and 242 feet long. The exact layout and use of the heiau are not fully known.
What the stones may have been used for
Poliahu Heiau may have been a luakini, a temple associated with ceremonies and offerings to the god Kū. Luakini sites are also linked with human sacrifice, but the precise role of this heiau has not been established. Its unusual stonework has inspired a tradition that the Menehune built it; the date of construction is also uncertain.
Signs at the site provide context for the remains. Take time to read them, while bearing in mind that some interpretations of the site’s history are presented as possibilities rather than established fact.
Respectful ways to visit
Walk around the stone remains without standing on the walls or entering the enclosed center. Do not leave offerings. These practices show respect for the site’s sacred importance to Native Hawaiians.
The bluff also makes Poliahu a viewpoint over the Wailua River valley. A path across the road leads to another river view, while the Opaekaʻa Falls viewpoint is nearby. The grounds have chickens and picnic tables; leave the birds unfed and look toward the greenery below, where wild pigs may be visible.
