If you’re doing the Road to Hana, this is the grand finale: a sheer 400-foot plunge down a lush cliff, tucked deep in the Kīpahulu District of Haleakalā National Park. It’s not a drive-up waterfall—you earn it—but the payoff is one of the most dramatic falls you can reach by trail on Maui.
Expect 3.4–4 miles roundtrip on a moderate trail that climbs steadily and can be slick after rain. The route is half the fun: you’ll pass a massive banyan tree, stroll raised walkways through a tunnel-like bamboo forest, cross a few bridges, and catch a viewpoint of 200-foot Makahiku Falls before the final reveal at Waimoku.
Waimoku shoots straight down a vertical pali into a rocky basin. It’s gorgeous—and it’s also serious terrain. Heed the posted warnings and keep your distance from the cliff and pool; rockfall and flash floods are real hazards, and swimming isn’t allowed.
This is a top highlight, so it gets busy, especially midday. The trail is rainforest-wet: mud, standing water, and slippery sections are common. Mosquitoes show up too—bring repellent. You’ll hear birds along the way and see plenty of lush vegetation; the bamboo grove is the undeniable star.
Park at the Kīpahulu Visitor Center area; the signed Pipiwai Trailhead is across the road. Restrooms are available at the trailhead, along with parking and a few picnic spots. Don’t count on food or potable water here—pack what you need. A campground exists in the Kīpahulu area, but there are no facilities at the falls themselves.
Start early (ideally before 10 a.m.) or make this your first stop in Kīpahulu to beat crowds and heat. Many visitors don’t reach this end of the Road to Hana until late afternoon, when parking and the trail are busiest. Waterflow varies with recent rain; the trail gets muddier when it’s been wet, and flash-flood warnings must be taken seriously.
There’s an entry fee for Haleakalā National Park (Kīpahulu District). Wear sturdy footwear, carry water and a rain layer, and respect all closures and warning signs—this valley can turn dangerous quickly.
