You step off the van into humid air that smells of wet earth and ʻōhiʻa — the forest seems to inhale and exhale around you as your guide leads a short under-one-mile walk to a 35-foot double-tiered waterfall. Water pulls at the pool below, daring you to linger while the ridge above opens out to a wide view of Windward Oʻahu.

History
The Koʻolau Range is the remnant of a massive shield volcano; its windward valleys have deep cultural ties through the Hawaiian ahupuaʻa land divisions and contain private parcels regarded as culturally sensitive.
Conservation
Much of the hike crosses privately managed forest set aside for stewardship—stay on the trail, avoid removing plants, and follow guide directions to reduce invasive species spread.
