Follow in the footsteps of the Vikings as you walk down into the rift valley where the American and Eurasian continental plates are literally pulling apart at Þingvellir National Park, a UNESCO World Heritage Site and the birthplace of the oldest existing parliament. Witness the steaming geothermal springs as the ground trembles and hot water spouts spectacularly skywards from the famous Strokkur Geyser at home of the one-and-only original geyser and Iceland's most iconic natural attraction. Experience the magnificence and power of Gullfoss Waterfall, a set of glacial river cascades falling 32 meters into a narrow canyon with a thunderous roar. The best part, this is all done within 8 hours!
Simply put, if you only do one tour in Iceland, then this should be the one!
