At Rainbow Falls, the Wailuku River rushes into a large pool below. The gorge is blanketed by lush, dense nonnative tropical rainforest and the turquoise colored pool is bordered by beautiful, although nonnative, wild ginger. Monstera is also in abundance. The falls are accessible via Wailuku River State Park, Waiānuenue Avenue, coordinates 19°43′9″N 155°6′34″W, and are best seen from the park’s viewing platform.
