What is a Hawaiian vacation without visiting a magnificent waterfall? It is incomplete! Hawaii is blessed with some of the most amazing waterfalls in the world. One of Discover Hawaii Tours favorite waterfalls is found on the Big Island of Hawaii, Rainbow Falls. Rainbow Falls is Fantastic! Rainbow Falls is an 80-foot tall waterfall found just outside of Hilo on the eastern side of the Big Island. Named for the rainbow that appears during misty mornings on the windward coast, this waterfall is an amazing sight to behold after a healthy rain. Its Hawaiian name is Waianuenue (rainbow water), and the large cave below the falls was believed to have been home to Hina, an ancient Hawaiian goddess. Discover Hawaii Tours stops at Rainbow Falls every day during our Big Island Volcano Evening Tour.
