Grímsey is a small island located 40 km North of mainland Iceland. It was formed by volcanic rock that has generated majestic basalt pillars. The island has been inhabited since the Vikings came to Iceland and legend has it that it is named after the colonial sailor Grìmur, who sailed from the region of Sogn in Norway. This site is home to fabulous wildlife, with many bird colonies having chosen to nest along the jagged cliffs, such as the ‘‘clowns of the sea’’ known as the Atlantic Puffins. While many travellers come here in order to cross the invisible line into the Arctic Circle, the island is also famed as a place to observe the midnight sun.
