- 1 Castlebar (Caisleán an Bharraigh) is the county town and market centre of Mayo.
- 2 Westport (Cathair na Mart) is the main base for visiting Clew Bay and the south of Mayo. Nearby is the pilgrimage mountain of Croagh Patrick.
- 3 Newport (Baile Uí Fhiacháin) is a very small village, yet the largest on the county's northwest coast.
- 4 Ballina (Béal an Átha) is the main town with accommodation in the north of Mayo.
- 5 Killala (Cill Ala), where the French invaded in 1798, is near several ruined abbeys.
- 6 Knock (Cnoc Mhuire) has a famous Marian Shrine and Ireland West Airport.
- 7 Cong (Conga) is an attractive little village with a ruined abbey, best known as the location for the 1952 film The Quiet Man.
- 8 Leenane (An Líonán) is a village on the south shore of Killary fjord, so it's just across the boundary into County Galway. But it's a good base for attractions in southwest Mayo, such as Doo Lough.
- 1 Achill Island is reached by road. It has a haunting deserted village.
- 2 Clare Island at the entrance to Clew Bay was the abode of "pirate queen" Gráinne O'Malley: her tower house still stands. The island is reached by ferry from Roonagh near Louisburgh.
- 3 Inishturk is inhabited and is also reached by ferry from Roonagh.
- 4 Mullet (or Erris) Peninsula is some 33 km long off the northwest coast, with two arms. At its south tip is Blacksod Lighthouse; its northern arm creates Broadhaven Bay. Eagle Island near its north tip has another much-battered lighthouse, and its twin has long succumbed to the Atlantic storms.
In legend, six races of gods conquered Ireland before the coming of mortal beings. When the fourth of these, the Fir Bolg, were overthrown, they were awarded Connacht by way of a peace token. Or perhaps it was a booby prize or "wooden spoon": so it might appear to anyone fated to farm these bleak lands with merely mortal strength. Mayo has been populated since the Stone Ages - they certainly didn't lack stones, but prehistoric forest clearance made a poor soil worse, until bog engulfed the land as at Céide Fields. The county boundaries were laid down in 1585: Mhaigh Eo (meaning Plain of Yew Trees) was at that time a significant abbey settlement, but the abbey disappeared long ago and Mayo village is a tiny place, never the county seat. County Mayo had a hand-to-mouth existence even in the good years and was hard hit by the famines. Mary Robinson, 7th President of Ireland and born in Ballina, described Mayo's western hills as "on the periphery of the periphery".
So the reason to come is for the wildness and quiet, in one of Ireland's most sparsely populated regions. That was why the French chose Killala for their invasion of 1798, catching the British unawares; that was why Hollywood picked Cong as the location for filming The Quiet Man. Why, even the airport at Knock is a strangely quiet place.
