Facts about County Mayo

Facts about Co. Mayo
Mayo, located on the west coast of Ireland, is the third largest county in Ireland.
It is a county with a rich and varied landscape, stretching from Lough Corrib and Killary Harbour, Ireland's only fjord, in the south, to Killala Bay in the north, and from the Atlantic to the west to counties Sligo and Roscommon in the east.
From east to west the landscape of Mayo ranges from relatively flat terrain interspersed with the island-studded lakes of Lough Conn, Lough Carra, and Lough Mask, to the rugged cliffs and islands of the Atlantic coast.
The blanket bogs in the north give way to the Nephin Beg range of mountains.
The famous Croagh Patrick (765m) lies to the south, and just above Killary harbour lies Mweelrea which, at 819m, is the highest peak in Connaught.
Mayo's chief rivers are the Moy, Deel, Palmerstown, Ballinglin, Glenamoy, Owenmore, Owening, Owenduff, Newport, Bunowen, and the Erriff.
