Rainbow Falls are located in Wailuku River State Park, in Hilo. They get their name from the fact that, in the mornings, rainbows often form in the mist from the falls (above).
At left, someone left an offering, possibly to Hina, mother of the demigod Maui, who is said to have lived in the cave behind the falls.
And below, someone who has inadvertently walked past the 83,000 ‘Danger’ and ‘Warning’ signs to wander around at the top of the falls. Flash floods occur often and people die here every year.
