A VERY popular tourist spot on the Big Island is Rainbow Falls, which sits in Wailuku River State Park just west of downtown Hilo on the Big Island, where the Wailuku River drops about 80 feet over a ledge of ancient lava. The Hawaiian name Waiānuenue means "rainbow seen in water" — on sunny mornings, sunlight hits the mist. Hawaiian legend says the cave behind the falls is the home of Hina, the mother of the demigod Māui.
