Courtmacsherry Bay is a sheltered tidal estuary on the southwest coast of County Cork, Ireland, renowned for its exceptional and diverse sea angling. The bay is formed at the mouth of the Argideen River, which enters between Wood Point and Lisheen Point, and features extensive tidal flats and muddy banks. It is part of a Special Area of Conservation, highlighting its ecological importance. The area is famous for producing large, record-sized fish, with a fishery that supports both prolific inshore sport and world-class offshore charter fishing within a short distance of the harbour. The village of Courtmacsherry itself is a historic settlement that developed as a maritime hub, offering a full suite of services for anglers seeking everything from bass on the beach to massive common skate over deep-water wrecks.
