St George's Channel is a major sea passage linking the Irish Sea to the Celtic Sea and the broader Atlantic Ocean, forming a significant marine corridor between southeastern Ireland and southwestern Wales. It is a wide, open body of saltwater, approximately 160 kilometers long and up to 76 kilometers wide at its broadest point between Carnsore Point in County Wexford and St. David's Head in Wales. The channel's geography creates a dynamic marine environment influenced by oceanic currents and tides, supporting a diverse range of inshore and offshore fish species. The Irish coastline along the channel, particularly in County Wexford, features a mix of sandy shorelines, lowlands, rocky points, and harbors that provide varied access for anglers.
