Located along the Hamakua Coast on the northeastern coast of the Big Island of Hawai'i, Waipi'o Valley is the largest and southernmost of the seven valleys on the windward side of the Kohala Mountains. Time and nature's elements have carved an unimaginably massive valley filled with deep green-encrusted cliffs cut by plunging waterfalls. Its floor is carpeted with forests and neatly formed taro patches interspersed with the homes of its few residents. At the mouth of the valley the ocean licks the mile-long black sand beach which is sliced in half by the river that is partially fed by the 1,200 ft. free-falling Hi'ilawe Falls which resides deep inside the valley. The road into the valley is incredibly steep and out of respect for the residents we do not encourage driving into the valley. However, we have been told that it is fine to walk in and hike to the beach, but do not explore the interior of the valley without a tour guide. Additionally you will need to hike across the beach to hike the Muliwai Trail or any portion of Z-Trail (which can be seen etched in the opposing wall from the official lookout). The view from the third switchback of Z-Trail offers the most amazing view Waipio Valley, and is well worth the effort to reach. https://www.hawaii-guide.com/big_island_of_hawaii/sights/waipio_valley
