Today was a day full of adventures and activities. We visited the area of the Lake Myvatn, where geothermal energy produces incredible landscapes. Bubbling mud pools, lunaresque volcanic craters, newborn lava fields, and steamy chimneys are the main attractions of this area. When it comes to birding Lake Myvatn offers great opportunities, and we were lucky enough to see the Harlequin Duck and the Barrow’s Goldeneye, among many other interesting birds and waterfowl. To end a great day, we visited Grimsey Island, where we crossed the Arctic Circle and observed one of our favorite seabirds, the Atlantic Puffin.
