The pockmarked road stretching from lookout down into the valley is steep and narrow at times, but if you’re willing to take the journey, it’s a place that will reveal the beauty of life’s simplicity. Several spectacular waterfalls are located in the valley: Kaluahine Falls, Waiulili Falls and Hiilawe Falls thats more than 1,400 feet tall, the tallest on the Big Island of Hawaii. If you’re in top physical shape, you might also consider hiking the 18-mile Muliwai Trai that will take you into the next valley, Waimanu Valley. You’ll need a permit to camp in Waimanu; call the Hawaii District State Division of Forestry & Wildlife not earlier than one month in advance.
