From Reykjavik we head out to Icelands highest waterfall Glymur, which hides in a deep, narrow canyon at the bottom of Hvalfjörður (Whalefjord). From there we pass by Skjaldbreiður shield volcano which last erupted 9.000 years ago forming the base of Þingvellir lake and national park. Following the Continental Rift line through the national park you will see deep cracks and crevices due tectonic plates pulling apart.
