The Galway Oyster Festival is dedicated to Ostrea edulis, the European flat oyster. The local molluscs are left to grow for three years in the clean waters of Brandon Bay and Clarenbridge, blooming into a juicy delicacy. Tens of thousands of the slippery critters are consumed on the Guinness Oyster Trail, on which 30 pubs give out free trays of the seafood with pints of the dark stuff.
