About Hiʻilawe Falls
Hiʻilawe Waterfall on Hawaiʻi Island is one of the tallest and most powerful waterfalls in the state, dropping about 1,450 feet (440 m) with a primary free-fall of roughly 1,201 feet (366 m) into the lush Waipiʻo Valley along Lalakea Stream. The ribbon-like cascade framed by steep, tropical valley walls is a dramatic sight when water is flowing, and its scale makes it a must-see landmark for visitors to the northern coast of the Big Island. Visitors should know that Lalakea Stream above the falls has been diverted for irrigation, so Hiʻilawe can be intermittent and may run dry even during normally wet months such as March. Approaching the base of the falls requires navigating steep, challenging terrain and sections of private property, so plan accordingly and respect any landowner restrictions and local guidance.
The Setting
Hiʻilawe Falls sits at 1,358 feet along the Alakahi Stream, in the foothills of Hawaii. At 1,450 feet, it is among the taller waterfalls in Hawaii.
Height: 1450 feet
Trail & Hike Details
The Approach
The hard 4.0-mile out-and-back trail gains 900 feet of elevation on the way to the falls.
Trail Description
Trail stats: 4.0 miles (out-and-back), ~900 feet elevation gain, rated hard. The route involves a steep descent into Waipiʻo Valley and then travel across streams and private parcels to get closer to the falls. Expect muddy, slippery sections and uneven footing; the trail is physically demanding and requires good footwear and experience with rough terrain. Note also that the falls’ flow is seasonally and operationally variable—Lalakea Stream has been diverted for irrigation—so the falls may have little or no water. Access to the immediate base of Hiʻilawe may be restricted due to private land ownership; check local access rules before attempting the approach.
What to Expect
The falls plunge a dramatic 1450 feet.
Accessibility
The trail involves steep, uneven terrain with significant elevation change and is not accessible to mobility devices.

How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.
