The Golden Circle road leads you to Iceland’s most popular sights: Gullfoss, Geysir and the National Park Thingvellir. There are also many more interesting places to stop at on the way, like the Geothermal Exhibition at Hellisheidi Power Plant, Faxi waterfalls and volcanic crater Kerid, for instance. The route covers approximately 300 kilomteres (190 miles), and loops from the capital of Reykjavík to the center of the country and back.
