About Keʻākū Falls

Keʻākū Falls sits within the Keanae‑Wailuanui Hawaiian Home Land and is stewarded by the local tribal land unit (Designation: TRIB; Manager: TRIB), with land ownership recorded as DESG. Framed by lush Hawaiian vegetation, the falls are a rewarding natural destination — known locally for their photogenic cascades and the sense of place they convey. Visitors are encouraged to respect tribal stewardship and any posted access guidance when planning a visit. For those who want to approach the falls on foot, the most commonly used route is a moderate out‑and‑back hike that provides a relatively short but satisfying excursion into the surrounding landscape. The nearest formal backcountry camping facility noted in records is in Haleakalā National Park (wilderness tent permit required), roughly 13.8 km from the trailhead, so most hikers treat Keʻākū Falls as a day outing rather than an overnight destination.

The Setting

Keʻākū Falls sits at 390 feet within Keanae-Wailuanui Hawaiian Home Land, fed by the West Wailuaiki Stream, in the coastal lowlands of Hawaii.

Trail & Hike Details

The Approach

The moderate 2.4-mile out-and-back trail gains 350 feet of elevation on the way to the falls.

Trail Description

This route is a 2.4‑mile out‑and‑back trail with approximately 350 feet of elevation gain and is rated moderate in difficulty. The trail’s length, elevation profile, and out‑and‑back character make it suitable for hikers looking for a shorter, steady climb with time to enjoy the falls at the turnaround. Surface, grade, and a formal trail classification or USFS trail number are not listed for this tribal‑managed route, so expect natural footpath conditions and consult local land‑unit guidance before setting out.

What to Expect

Visitors can expect a breathtaking view of the falls cascading into a pool below, surrounded by tropical vegetation. The lookout point provides a safe and convenient way to enjoy the scenery without the need for hiking.

Accessibility

The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.
