Clew Bay SAC is a protected marine and coastal area known for its rich biodiversity and numerous small islands, offering unique opportunities for marine wildlife observation and coastal exploration.
Clew Bay SAC (Special Area of Conservation) is located along the northwest coast of County Mayo, Ireland. It encompasses Clew Bay, a large bay dotted with around 365 islands, known colloquially as "the islands of Clew Bay." The SAC covers a mosaic of habitats including marine waters, seaweed beds, sandbanks, mudflats, rocky shores, and coastal areas that support a diverse array of flora and fauna. The bay is particularly important for its extensive intertidal mudflats and sandbanks which provide prime feeding grounds for migratory birds and nursery habitats for fish species. Key ecological interests include otters, harbor porpoises, seals, and notable bird species such as the common tern and peregrine falcon. Historically, Clew Bay has been influential in Irish heritage, with archaeological sites like old monastic settlements and medieval castles scattered around its coastline and islands. Visitors to the area are drawn to its serene natural beauty and opportunities for kayaking, birdwatching, hiking along the coastal routes, and island hopping by boat. The combination of rich biodiversity, scenic landscapes, and cultural landmarks makes Clew Bay SAC a cherished destination for nature lovers and outdoor enthusiasts. Conservation efforts focus on protecting the sensitive habitats and species from human disturbance and environmental pressures, supporting sustainable use and ecological research throughout the bay.
