After a hard rain, these falls thunder into the Wailuku River gorge, often creating magical rainbows in the mist. Sometimes known as the "Hilo Town Falls," they are located just above downtown Hilo. Take Waianuenue Avenue west for a mile; when the road forks, stay right and look for the Hawaiian warrior sign. Open daylight hours.
