Sk?????gafoss, Iceland - 25 May 2006. Skogafoss is one of the most spectacularly beautiful waterfalls in Iceland. And that really means something in a country that's packed with them! This one lies on the Sk?????g????River in the south of Iceland, at the cliff marking the former coastline. Such is the constant spray that there is often a rainbow or even double rainbow to be seen at the base of the falls. But here we see a lone seagull flying free by the waterfall.
