Taro Field in the Waipio Valley - Waipio means curved water in the Hawaiian language. It was the residence of many early Hawaiian kings - the large nioi tree was the location of the grass palace of the ancient kings. A steep road leads down into the valley from a lookout point - one of the steepest roads in the world. Several waterfalls pour into the valley to feed the river. A foot trail called Muliwai Trail leads down a steep path to the Waimanu Valley. The valley was the site of the final scene in the science fiction film Waterworld where the main characters finally found dry land.
