Lulumahu Falls is a cascade waterfall in Hawaii with a documented drop of 50 ft (15 m).
The falls are fed by Lulumahu Stream (Nuʻuanu drainage). It lies in Honolulu, Hawaii. The site is on public land managed by Hawaii Division of Forestry and Wildlife - Honolulu Watershed Forest Reserve (permit required).
This is a short hike waterfall: reached by a short trail, generally under about a mile each way. The walk to the main viewpoint runs about 1.8 miles round trip. The nearest town is Honolulu (Nuʻuanu).
When to go: Year-round (muddy and best flow after rain; flash-flood risk). Like most waterfalls, Lulumahu Falls runs highest after snowmelt or heavy rain and can thin out in late summer, so it's worth checking recent streamflow and the land manager's conditions page before a long drive.
