Beautiful! I also love waterfalls, and this one looks so ornamental. Astonishing that it keeps that temperature of 27˚C.
I've been reading a lot about mineral-rich rocks recently, as preparation for my Mountain Leader Award, and the types of minerals in the rocks affect the type of vegetation that grows around it (as well as the invertebrates that live there, etc). So I guess that's why it looks so lush and green!
