About Pūwainui Falls

Pūwainui Falls is a secluded, picture-postcard cascade tucked into the Halele'a Forest Reserve on the island of Hawaiʻi. Surrounded by lush native vegetation, the falls reward visitors who make the effort with a tranquil setting and the sense of getting off the beaten path. The parcel is designated PCON and is privately owned and managed (PVT), so visitors should be mindful that access is more restricted than at public parks and confirm permission before planning a visit. The approach to the falls follows a moderately rated out-and-back route of about 2.4 miles with roughly 350 feet of elevation gain, making it a satisfying half-day outing for hikers comfortable with uneven, less-maintained trails. Because the land is privately managed, consider contacting local stewards, guides, or tour operators for the most current access information and route guidance before heading out.

The Setting

Pūwainui Falls sits at 984 feet within Halele'a Forest Reserve, fed by the Wainiha River, in the foothills of Hawaii.

Nearby Falls Worth Visiting

Hanakāpīʻai Falls (300 ft) lies 4.2 miles to the northwest.

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.

Weather Forecast

The Terrain, Seen by LiDAR

Aircraft-mounted lasers measured this ground to within inches. Trees and buildings are digitally stripped away, leaving the bare shape of the land the water has carved.

1-meter lidar measures about 91 feet of descent through Pūwainui Falls, a steep tiered drop rather than a single free fall. The brink sits at about 984 feet above sea level.

The whole reach is steep: about 166 feet of descent in the 500 feet above the falls and another 88 feet in the 500 feet below. The falls face west and glow in afternoon and evening light.
