The cloudy sky and the waterfall Gulfoss, Iceland, almost mix it up like they are one, don't they? Great picture. Come and see this nature wonder for yourself, when traveling Iceland. It is a stop at the popular tourist bus tour The Golden Circle tour, which takes you to the great wonders and sights in south and west Iceland. It is stunning both in winter and summer. And remember your camera, so you can photograph the powerful waterfall - perhaps you will catch a great sky as well.
