The fourth day began with an attempt to reach Svartifoss. It was a long trek from our camping ground on a thin manmade path through dense shrubs and beautiful wild flowers. Although we could not finally reach Svartifoss due to lack of time the attempt was worth remembering. From here we moved to another famous natural marvel of Iceland, the glacial lagoon Jokursarlon in southeast Iceland, on the edge of Vatnajökull National Park. This lake had icebergs some of which are 1000 years old. A lot of aquatic and avian fauna was also visible including Arctic Terns and Seals. We had also planned for a tour on an amphibian boat along the lake but was there were paucity of tickets. The color of the icebergs were clear blue, it is here that I finally understood why the “white walkers” in Game of Thrones have blue eyes because earlier I always thought ice to be white. From Jokursarlon we had an epic drive for more than 400 kms right upto the shores of Lake Myvatn where we camped for the night. While on the way to Myvatn we stopped for diesel at Hofn. We reached Myvatn late at night at about 1:00 AM and set up our camps at the shore of the lake. It off course did not matter as there was still enough daylight to set up our tents and cook dinner.
