Lulumahu Falls

Lulumahu Falls rewards hikers with a secluded 50-foot waterfall in Nuuanu Valley's dense rainforest. This moderate 2.5-mile round-trip trail follows an old irrigation ditch through thick tropical vegetation, crossing multiple stream beds before reaching the cascade and swimming hole. The trail begins behind residential homes on upper Nuuanu Pali Drive and immediately drops into heavy forest cover. Muddy, slippery conditions persist year-round as you navigate exposed roots, loose rocks, and stream crossings. The path becomes faint in several sections, so download offline maps before leaving home. Waterproof hiking boots with aggressive tread patterns prevent dangerous slips on wet rocks and mud. Intermediate hikers who handle uneven terrain and water crossings find this trail ideal for escaping crowded tourist areas. The swimming hole at the base provides refreshing relief, though water stays cool since minimal sunlight penetrates the thick canopy overhead. Park along Nuuanu Pali Drive near the residential access point, which fills completely by 9 AM on weekends. No entrance fees apply. Start between 6-8 AM for optimal lighting and smaller crowds. Afternoon thunderstorms from October through April create hazardous conditions and flash flood risks. Pack extra water, energy snacks, waterproof bags for phones and cameras, and consider yaktrax or similar traction devices during rainy season. Heavy rains transform gentle stream crossings into dangerous torrents within minutes. Check weather forecasts and recent trail reports before departing. Cell service vanishes once you enter the forest, so share your hiking timeline with someone reliable. Plan three hours total for a comfortable pace with swimming time.
