Viewpoints of geologic and scenic interests along Wailuku River. Boiling Pots is a succession of big pools connected by underground flow or cascades and whose waters roll and bubbles as if boiling; the well-exposed hexagonal columns that line the pools were formed by the slow cooling of basalt lavas. 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.
