About Orkney Islands Coast Site of Special Scientific Interest (SSSI)

 

The Orkney Islands Coast Site of Special Scientific Interest (SSSI) is a designation covering multiple coastal stretches across the Orkney archipelago in northern Scotland. This protected area includes rugged cliffs, sandy bays, intertidal habitats, and sea stacks, which support significant biodiversity and geological features of national importance. The coastlines of Orkney are recognized for their rich birdlife, including important breeding sites for seabirds such as puffins, guillemots, and kittiwakes. The varied habitats also harbor rare and fragile plant communities adapted to the maritime environment. Geologically, the Orkney coast provides excellent exposures of Old Red Sandstone and other formations that offer valuable insights into Scotland’s ancient past. Archaeological remains along the coast, including remnants of Neolithic settlements and Norse sites, add a cultural heritage dimension to the landscape. Visitors to the Orkney Islands Coast SSSI can engage in a range of outdoor activities such as coastal walks, birdwatching, photography, and exploring historic sites. Many trails and informal footpaths allow access to scenic viewpoints and secluded beaches. The region’s relatively mild, though often windy climate supports year-round exploration, with summer months best for bird colonies and wildflower displays. The coastline is largely unspoiled, making it an appealing destination for nature enthusiasts seeking remote and undisturbed environments. Protection under the SSSI status ensures key habitats and species are conserved, maintaining ecological integrity and enabling continued scientific research. The area is managed with consideration to balancing public enjoyment and habitat preservation.
