Clew Bay is a large, sheltered Atlantic bay on the west coast of County Mayo, renowned as one of the premier sea angling destinations in Ireland. The bay is roughly rectangular, approximately 25 kilometers long and 12.5 kilometers wide, and is famously dotted with over a hundred drumlin islands, creating a unique and protected inshore environment. It is overlooked by the iconic peak of Croagh Patrick to the south and the Nephin Beg Mountains to the north, offering stunning scenery. The bay's complex coastline and numerous islands provide exceptional shelter, making it an all-weather fishing venue. Historically the heart of the territory of the O'Malley clan, including the pirate queen Grace O'Malley, Clew Bay is now a significant hub for both recreational angling and sustainable commercial shellfish fisheries. The settlements of Westport, Newport, and Mulranny serve as primary gateways for anglers.
