About Hoʻopōuli Falls

Hoʻopōuli Falls is a quiet, lesser-known waterfall set within the lush tropical surroundings of Halele'a Forest Reserve on the island of Hawaii. Tucked away from heavy visitor traffic, the falls offer a serene spot for hikers who appreciate green, forested canyons and a sense of solitude. The site’s designation as PCON and its private ownership and management (PVT) mean it remains off the beaten path and relatively unadvertised, keeping the setting naturally intact. Because the waterfall sits on privately managed land, visitors should be mindful of access restrictions and posted signs; seeking permission before entering private property is recommended. The approach to the falls is rewarding for hikers who prefer quieter trails: the route is an out-and-back approximately 2.4 miles with about 350 feet of elevation gain and is generally rated moderate — a pleasant half-day outing for those prepared for uneven forest terrain.

The Setting

Hoʻopōuli Falls sits at 614 feet within Halele'a Forest Reserve, fed by the Hanalei River, in the foothills of Hawaii.

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 210 feet of descent through Hoʻopōuli Falls, a steep tiered drop rather than a single free fall. The brink sits at about 572 feet above sea level.

Steep ground runs through the entire stretch: about 363 feet of descent in the 500 feet above the pin and 188 feet in the 500 feet below it. Facing southwest, the falls sit in full sun for most of the day, best photographed early or late.
