Mayo is a county in the middle of the west coast of Ireland . It is bounded on the north and west by the Atlantic Ocean; to the south by County Galway; the east by County Roscommon; and the northeast by County Sligo. Mayo is the third-largest of Ireland’s 32 counties in area.

There is a huge variety of landscapes in County Mayo, from the lakes in the east to the Atlantic coast with its beaches and cliffs in the west..

  • The highest point in Mayo (and Connacht) is Mweelrea, at 814 m (2,671 ft) but the most widely known and recognised mountain is Croagh Patrick. This mountain is a favourite climb and there is an annual day of  pilgrimage to the top when thousands climb it.  This is usually the last sunday in July and there is a lot of people and a great atmoshphere.  Make sure to bring a drink as it gets very expensive at the top!
  • Ireland’s largest island, Achill Island, lies off Mayo’s west coast. You can drive to it over a bridge. The Island also has some of the most attractive beaches on the West Coast.
  • Mayo has Ireland’s highest cliffs at Croaghaun, Achill Island, while the Benwee Head cliffs in Kilcommon Erris drop almost perpendicularly 900 feet (270 m) into the Atlantic Ocean. A great spot for watching seabirds, seals, whales and dolphins.
  • The Great Western Greenway is a greenway rail trail in County Mayo, Ireland. It is 42 kilometres long and begins in Westport and ends in Achill, passing through the towns of Newport and Mulranny as it runs along the coast of Clew Bay.

  • The River Moy in the northeast of the county is renowned for its salmon fishing. The river Moy has more salmon running its system than the whole of Scotland. The Ridge Pool in Ballina is possibly the most productive salmon fishery in Ireland . Brown trout enthusiasts will have to make do with Lough Cara, Lough Mask and Lough Corrib.
