One popular story is about the goddess Hina and her demi-god son, Maui. Legend says that in Hilo, Hawai’i, by the Wailuku River, Hina, lived in a cave where she worked to make bark cloth. While Maui was away, another figure named Lono-kaheo, a monstrous lizard, Mo’o Kuna (or sometimes Kuna the eel) tries to win her over. When she rejects him, so Lono-kaheo almost drowns her. She calls Maui for help.

Maui chases the lizard upstream to another waterfall called Boiling Pots. He asks the fire goddess Pele for help and Pele answers. When lava entered the river, it boiled away the water, revealing the hiding lizard. Maui defeated Lono-kaheo, by turning him into lava rock that surrounds the river today. The boiling water at Boiling Pots is a reminder of this epic tale. Today, it’s believed that Lono-kaheo rests deep within the Boiling Pots, ready to claim its next victim by pulling them into the underwater tubes. While the exact count remains uncertain, locals believe that the Wailuku River takes one life each year, earning its reputation as Hawaii’s most perilous river. The legend of the Wailuku River was so named in the Hawaiian tongue Wailuku means literally “destroying water.”
