It is surely a wonder of the wild. It is a tall, but thin falling water fall. It falls over a granite cliff. It is rather humid around there and mist hangs every where. The lake at the bottom is dark blue and the water churns almost violently from the water fall. Its loud and hard to hear. There is a cave behind the water fall, but you can only get there by going to the top of the cliff and walking down a thin rocky ledge that leads to the opening behind the water fall. Now, the reason that it is called Rainbow Waterfall is because in the right light, and at the right time of the day, you can see the rainbow stretch over the peak of the waterfall.
