Although Iceland’s climate is not as severe as its name would suggest, its North Atlantic location does bring plenty of rain and snow, producing huge glaciers. The summer melt feeds many rivers, which because of the topography thunder down over countless waterfalls. From the mighty Detifoss, in north-eastern Iceland, reputed to be Europe’s most powerful waterfall, to small cascades. One of the largest waterfalls in Iceland and a magnet for tourists is Gullfoss (Golden Falls) on the Hvítá River, in the southwest of the island. On a sunny day the mists thrown up by the falls are filled with all the colours of the rainbow. A superb spectacle.
