Iceland has 'enormous' well covered!
Gullfoss is one of Iceland's most spectacular waterfalls - the Hvita river sends enormous quantities of water hurtling down in two stages at angles to each other. See the tiny people on the rocks at the edge of the falls - no safety rails in Iceland - just be sensible and don't get too close to the edge! Once you are down there the roar of the water is almost overwhelming as it hurtles over the massive rock faces. Worth the walk :)
