The Golden Circle is without a doubt, the most popular sightseeing route in Iceland. The trio that makes up the Golden Circle is the historical Thingvellir (Þingvellir) National Park, a UNESCO Heritage Site; the legendary Geysir, a bubbling hot spring that shoots boiling hot water into the air; and the magnificent Gullfoss or Golden waterfall, a powerful double waterfall that will take your breath away. Check out our day and multi-day tours that include visits to the Iceland Golden Circle.
