About Kaukiuki Falls

Kaukiuki Falls is a tucked-away waterfall in Hawai‘i reached by a moderate out-and-back hike through lush tropical vegetation. The route to the cascade covers about 2.4 miles with roughly 350 feet of elevation gain, rewarding hikers with a quiet, verdant setting where the sound of falling water slices through the forest canopy. It’s a lesser-known spot—ideal for those seeking a peaceful waterfall away from busier tourist sites. The falls and the access corridor lie within a Private Landowner Watershed Protection Area managed by PVT, so access may be subject to permission or seasonal restrictions. Visitors should verify access with the landowner or local contacts before heading out, and come prepared with sturdy shoes, water, and a leave-no-trace mindset to help protect this sensitive watershed area.

The Setting

Kaukiuki Falls sits at 1,230 feet within Private Landowner Watershed Protection Area, in the foothills of Hawaii.

Nearby Falls Worth Visiting

Manawaiopuna Falls (400 ft) lies 2.5 miles to the north.

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 199 feet of descent through Kaukiuki Falls, a steep tiered drop rather than a single free fall. The brink sits at about 1,254 feet above sea level.

The ground changes about 134 feet in the 500 feet above the falls and 52 feet in the 500 feet below. The falls face southwest and glow in afternoon and evening light.
