Mānoa Falls is a waterfall in Mānoa, on the island of O'ahu in Hawai'i, featuring a vertical drop of about 150 feet (46 m). It is accessible from the nearest road by a hike of approximately 1.5 miles (2.4 km). The length of the hike will take approximately 2 hours to reach the waterfall. The hike passes through many ecosystems and feels like an arboretum, which makes it a great photo-zone.
