An often missed but fascinating site on Oahu is the Ulupō Heiau on the Windward side of the island near the beach town of Kailua. It sits on the eastern edge of Kawai Nui Marsh which is off to your left as you come into Kailua down the Pali Highway. Stories say that it was created by the Menehune, an ancient race of leprechan-like pre-Hawaiians who inhabited the islands before Tahitian voyagers got here. There are many such large Menehune credited structures throughout the islands. The name Ulupo means 'night inspiration'. I can only imagine what it is like at night.
