Above we see beautiful Rainbow Falls in Hilo. The falls are fed by the Wailuku river outside of Hilo. The falls very in the amount of flow per day do to the changes in weather. This is a must see if you are going through Hilo. There is a short walk you can take through the rainforest to get a better vantage point of the falls and to see a massive banyon tree.

The Wailuku river also feeds Akaka Falls.
