    Description

    Viewpoints of geologic and scenic interest along Wailuku River. There are two separate park areas.  Boiling Pots is a succession of big pools connected by underground flow or cascades and whose waters roll and bubble as if boiling. The exposed hexagonal columns that line the pools were formed by the slow cooling of basalt lava. The 80-foot Rainbow Falls is renowned for the rainbow formed from its mist many mornings. Legends say that the cave beneath the waterfall was the home of Hina, mother of the demigod Maui. (16.3 acres)

    Location

    Both park sections are accessed via Waiānuenue Avenue, downtown Hilo; Boiling Pots Area at the end of Peʻepeʻe Falls Drive; Rainbow Falls Area on Rainbow Drive.
