Mayo sits between Galway's fame and Donegal's remoteness, and somehow gets overlooked by both comparisons. That is exactly its appeal. This is a county with a holy mountain, Europe's oldest known field system, an island where the last monks held out against modernity, and a coastline that runs from the surfing beaches of Mulranny to the sea cliffs of Belmullet - and almost none of it is crowded.
The county has two distinct halves. East Mayo is farmland, quiet towns, and the pilgrim trail to Knock Shrine. West Mayo is where the landscape turns dramatic - Clew Bay with its 365 islands, Achill Island connected by a bridge to the mainland, and the Bangor Trail through the Nephin Beg wilderness where you can walk for a full day without seeing another person. Westport ties it all together - a planned Georgian town that is consistently voted the best place to live in Ireland, and it is not hard to see why.
Know before you go
Mayo is bigger than it looks on the map and the roads in the west are slow. The R319 to Achill and the coast roads around Belmullet are single-track in places. Do not plan to cover the whole county in a weekend. Pick either Westport and Clew Bay or Achill and the north coast, and do one properly.
