The Shannon Estuary is a vast and sheltered tidal estuary formed over the final 80 kilometers of the River Shannon's journey to the Atlantic Ocean. It stretches from Limerick City out to the sea, bordered by County Clare to the north and counties Kerry and Limerick to the south. This major estuary is renowned for its permanently coloured water, which provides excellent daytime fishing opportunities year-round. It offers a diverse and productive fishery, from sheltered inshore marks to the wild Atlantic waters off Loop Head, supporting a wide array of species and catering to shore anglers, small boat operators, and deep-sea charter vessels alike.
