Hi'ilawe Falls

Hi'ilawe Falls is the tallest waterfall in Hawaii, plunging approximately 1,450 feet down the sheer back wall of Waipio Valley on the Big Island's remote Hamakua Coast. The falls drop in a staggering free-fall from the rim of the valley into the lush tropical floor below, often splitting into multiple ribbons that float and dance in the wind before reaching the bottom. On days with strong trade winds, the water is blown sideways off the cliff face entirely, creating an ethereal reverse waterfall effect visible from miles away.

Reaching Hi'ilawe requires first descending the notoriously steep Waipio Valley Road — a 25% grade that requires 4WD or a very long, steep walk. From the valley floor, the falls are visible across taro fields and river channels, though the base is on private land and access is not permitted without permission from landowners. Most visitors view the falls from the valley floor at a distance, which still provides spectacular views of the full cascade against the 2,000-foot valley walls.

Waipio Valley is a sacred place in Hawaiian culture — the Valley of the Kings where ancient Hawaiian royalty lived and are buried. Treat the area with respect. The falls are seasonal, running best from November through April during the wet season. In dry months, the flow can diminish to a thin trickle or stop entirely. The Waipio Valley Lookout at the top of the access road provides a panoramic view if you prefer not to descend.
