About Clew Bay Special Protection Area

Clew Bay Special Protection Area is a protected coastal and marine habitat in western Ireland, renowned for its rich biodiversity, stunning island-studded bay, and important bird nesting sites offering exceptional opportunities for wildlife viewing and sea-based recreation.

Wilderness Landscape & Natural Heritage

Clew Bay Special Protection Area (SPA) is a designated conservation site located on the west coast of Ireland, in County Mayo, within the Connacht region. The bay is famous for its unique geography, characterized by over one hundred islands of varying sizes scattered across the bay's sheltered waters. This archipelago creates a diverse mosaic of marine, coastal, and island habitats including shallow sea areas, mudflats, saltmarshes, and rocky shorelines. Ecologically, Clew Bay SPA is recognized primarily for its role as a vital habitat for a variety of seabird and waterfowl species, including nationally important populations of breeding terns, shelduck, and other migratory and resident birds. Notable species include the Sandwich tern and common tern, alongside important overwintering populations of wading birds such as the oystercatcher and curlew.

Historically, the bay and its islands have been shaped by centuries of human use including fishing, small-scale farming, and traditional maritime activities, which continue to contribute to the landscape's character and biodiversity. The area’s cultural heritage is reflected in local fishing villages and historical sites scattered on some of the larger islands.

For visitors, Clew Bay SPA offers numerous outdoor recreation opportunities focused on nature appreciation and low-impact activities. Birdwatching, kayaking, sailing, and scenic island-hopping are popular ways to experience the area's striking scenery and abundant wildlife. The bay's waters and coastline are also a draw for anglers targeting a variety of fish, as well as for photographers capturing its dramatic seascapes. While there are no extensive trail systems within the SPA itself, nearby walking routes and coastal paths around towns such as Westport provide access to the bay’s vistas and wildlife. Its blend of natural beauty, wildlife significance, and cultural heritage make Clew Bay SPA a valued destination for eco-tourists and outdoor enthusiasts.
