Gulfoss is a waterfall in Iceland. It is part of the Golden Circle tour, which is a popular tour that many tourists take. The Golden Circle shows you the national park Þingvellir, the waterfall Gullfoss (meaning "golden falls"), and the geothermally active valley of Haukadalur, which contains the geysers (erupting hot-springs). In Icelandic, 'Gul' means 'Gold' or 'Golden' and 'Foss' translates into 'Fall'.
