Rainbow appears at sunset over Waimea Kauai Hawaii


Due to the topography of Mount Wai`ale`ale, the rains form on the northeast side of the crater, then blow directly over to the southwest side. Be anywhere near the west side after midday and you are almost guaranteed to see a vibrant rainbow in Waimea Canyon.
