Rainbow Falls

When we left the town of Volcano, on the big island, right near Hawaii Volcanoes National Park, we drove to the town of Hilo on the east side of the island.  There we found Rainbow Falls which is 80 feet tall and pours into a pool below.  It is surrounded by vegetation that strangely enough, is not tropical, according to Wikipedia. It is a beautiful falls, but there was no sign of any rainbows.  We were there in the afternoon, and I am thinking that you would have to be there in the morning when the sun was shining on the falls.  Man, there are photographs at every turn in this landscape.
