From Honoka'a town, visitors continue north via Highway 240 or HI 24 to reach spectacular Waipio Valley, one of the most beautiful places in all of Hawaii. Many uninformed visitors simply drive up to the... Waipio Valley Lookout, take a few photos of the splendid panoramic scene in front of them from the topside (think 2,000-foot high sheer cliffs, magnificent Kaluahine Falls, and a secluded black sand beach), and then move on to the next destination on their list. Not so fast.
