Folklore in Hawaii in modern times is a mixture of various aspects of Hawaiian mythology and various urban legends that have been passed on regarding various places in the Hawaiian islands. The following is a partial list of some of these legends.
According to Hawaiian legend, night marchers (huaka‘i po in Hawaiian) are ghosts of ancient warriors. They supposedly roam large sections of the island chain, and can be seen by groups of torches. They can usually be found in areas that were once large battlefields (the Nuuanu Pali on the island of Oahu is a good example.) Legend has it that if you look a night marcher straight in the eye, you will be forced to walk among them for eternity, but if you have a relative taken by them, you will be spared. Hawaiians say that in the presence of night marchers, one should lie down on their stomach, face down to avoid eye contact, stay quiet, breathe shallowly, and don’t move. Some say that they may nudge you to provoke a reaction so they can take you. Moanalua Gardens is one of the many places the Night Marchers are said to roam.
Local folklore on the island of Oahu says that one should never carry pork over the Pali Highway connecting Honolulu and Windward Oahu. The stories vary, but the classic legend is that if one carries pork of any kind over the old Pali road (not the modern pali highway) by automobile, the automobile would stop at a certain point on the way and not restart until the pork is removed from the vehicle.
This legend has its roots in ancient Hawaiian mythology. According to legend, the Hawaiian volcano goddess Pele and the demigod Kamapua‘a (a half-man-half-pig) had a turbulent relationship, and the two agreed not to visit each other. If one takes pork over the Pali, the legend goes, one is symbolically taking a piece of Kamapua‘a from one side to the other, and it is said that Pele would stop that from happening.
Alternately, the legend is attributed to a magic dog, which was killed and cooked and put in an 'umeke to be carried over the pali and given as a gift to the mother/wife of the perpetrator. Women did not eat pork in ancient Hawaii, but were allowed to eat dog. The dog's owner followed and called to the dog, which came alive, answered from within the 'umeke, causing the carrier to drop his pole and flee. The dog then returns to its master. A dog as food was offensive to the American missionaries, and under their influence, the dog meat in the story became pork. The Pele/Kamapua'a stories were adapted to make the story fit, the old lady in the white holoku is also Pele, but that too was corrupted from other tales.
