Grótta

Grótta is a lush, land-connected island located at the outermost point of Seltjarnarnes, a unique natural gem. Grótta and its surrounding nature form a beautiful and popular outdoor recreation area for the residents of Seltjarnarnes and others who enjoy outdoor activities near the sea, with its rich and diverse birdlife. Grótta was designated as a nature reserve in 1974, with its conservation value primarily lying in its diverse birdlife throughout the year and its importance as a breeding ground in the summer. The most notable species are the hundreds of Arctic terns that nest in and around the island; since the Arctic tern is fully protected, access to the area is prohibited during the nesting season from May 1 to July 15. In addition to the Arctic tern, many other bird species can be found on the island, such as the eider duck, fulmar, sanderling, and oystercatcher. During the winter, Grótta serves as a common stopover for large groups of migratory birds that stay for varying lengths of time, including species such as the red knot and purple sandpiper. The area around Grótta is rich in marine life, with numerous tidal pools and coastal shores. Visitors can walk to Grótta at low tide and stay for up to six hours, but it is important to follow the tide table when traveling to and from the island, as the causeway connecting it to the mainland becomes submerged at high tide.
