Clew Bay Complex Special Area of Conservation Adventures

The Clew Bay Complex Special Area of Conservation (SAC) encompasses a diverse network of islands, estuaries, bays, and coastal habitats located off the west coast of County Mayo, Ireland. It covers a mosaic of marine and terrestrial environments, including island machair grasslands, calcareous grasslands, sea caves, reefs, and sheltered bays. Famous for its ’400 islands,’ Clew Bay offers a spectacular setting for nature lovers and outdoor enthusiasts. The area supports important populations of marine flora and fauna, including species such as lagoon sand shrimp, otters, wintering waterbirds, and rare seagrass beds that contribute to healthy fisheries and marine biodiversity. Historically, the bay holds archaeological significance with remnants of early monastic sites and medieval settlements scattered across the islands. Recreational opportunities focus on sea kayaking, boat tours, birdwatching, fishing, and hiking on some of the accessible islands and coastal paths. Visitors enjoy exploring the sheltered waters with spectacular views of the Atlantic horizon and diverse habitats from salt marshes to limestone pavements. Clew Bay's relative remoteness ensures a peaceful, natural experience while its proximity to towns like Westport and Castlebar provide convenient access for travelers. The protected status helps preserve its exceptional habitats and species while promoting sustainable recreation and eco-tourism in the region.
