Waihilau Falls

Waihilau Falls is a waterfall in Waimanu Valley that plunges in three thin streams down a steep cliff face covered in lush green vegetation. The water drops from a great height into several small pools along the descent.

This waterfall formed through erosion on the slopes of the extinct Kohala Volcano over long periods. This geological process shaped the current form of the falls and the surrounding terrain.

The falls contribute to the natural heritage of Hawaii County, standing as the third highest waterfall in Hawaii and thirteenth globally.

Reaching this waterfall requires a demanding hike of several hours from Waipio Valley through Waimanu Valley. The route crosses ridges and uneven terrain, so good physical fitness and proper hiking boots are essential.

The water descends in three separate threads that form a distinctive segmented pattern. This unusual appearance results from the cliff structure and how the water flows across it.
