Nu'uanu Pali Lookout is considered haunted due to the historical Battle of Nu'uanu in 1795, where many warriors died, and is associated with the Pali Highway and its Old Pali Road. Reported paranormal phenomena include the sightings of marching night marchers, shadowy figures, and the sounds of drums and stomping feet. There are also local legends of a mo'o wahine (lizard woman) who lures men to their deaths and an older folk belief to avoid carrying pork over the pass, especially at night. The location is known for a pivotal battle where King Kamehameha I's warriors forced hundreds of soldiers from Maui to their deaths by being pushed or jumping off the cliff, a site of intense spiritual significance. The Old Pali Road was built over ancient Hawaiian footpaths, connecting to the area's strong spiritual history. Night Marchers: Specters of ancient Hawaiian warriors are said to march through the valley at night. These spirits are often accompanied by the sound of pu (conch shell) horns, rhythmic drumming, the stamping of feet, and a procession of torches. Visitors have reported seeing large, shadowy figures that change shape, such as a man sitting on a hill that turns into an animal. According to legend, a mo'o wahine, a lizard spirit in the form of a beautiful woman, inhabits the pass and leads men to their deaths off the cliff. The presence of night marchers is sometimes accompanied by a distinct smell of sulfur. Hawaiian folklore advises against carrying pork over the Pali Highway, particularly at night, to avoid disturbing spirits.
