The Golden Circle is a popular tourist route in South Iceland, covering about 300 km looping from Reykjavík into central Iceland and back. The three primary stops on the route are the national park Þingvellir, the waterfall Gullfoss (meaning “golden falls”), and the geothermally active valley of Haukadalur, which contains the geysers Geysir and Strokkur. Though Geysir has been inactive for a long time, Strokkur, on the other hand, continues to erupt at every 5-10 minutes interval. Other stops include Kerið volcano crater, Hveragerði greenhouse village, Skálholt church, and the Nesjavellir or Hellisheidarvirkjun geothermal power plant.
