Rainbow Falls (Waiānuenue) is a plunge waterfall in Hawaii with a documented drop of 80 ft (24 m).
The falls are fed by Wailuku River. It lies in Hawaii, Hawaii. The site is on public land managed by Hawaii Division of State Parks - Wailuku River State Park.
This is a roadside waterfall: visible from a road, parking area, or a walk of a few hundred feet. The nearest town is Hilo.
When to go: Year-round (best flow after rain; morning light produces rainbows). Like most waterfalls, Rainbow Falls (Waiānuenue) runs highest after snowmelt or heavy rain and can thin out in late summer, so it's worth checking recent streamflow and the land manager's conditions page before a long drive.
