About Clew Bay Special Area of Conservation

 

Located on the Atlantic coast of County Mayo, Ireland, Clew Bay Special Area of Conservation (SAC) encompasses a spectacular marine and coastal ecosystem including numerous islands, rocky shores, sandy beaches, and underwater habitats. The bay itself is dotted with about 365 islands, creating a unique landscape often associated with serene beauty and ecological value. The SAC was designated to protect habitats such as reef systems, sea caves, sandbanks, and estuaries, which support a variety of marine flora and fauna, including sensitive species such as the harbour seal and otter. The coastline and waters are vital for seabirds, fish, and invertebrates, protecting biodiversity and spawning grounds. Historically, the bay has been an important fishing and maritime area, with archaeological sites including ancient settlements scattered across some islands. Visitors to Clew Bay have access to activities including kayaking, sailing, birdwatching, and island hopping, although the area is relatively undeveloped to preserve its natural state. The nearby town of Westport offers services and access points to the bay. Clew Bay SAC exemplifies a rare coastal ecosystem where conservation efforts work alongside traditional local fishing and tourism. Its scenic vistas, combined with rich wildlife and outdoor recreation, offer a rewarding destination for nature lovers and outdoor enthusiasts seeking a quiet yet captivating Irish coastal experience.
