County Mayo
Galway's quieter, wilder neighbour. A county with Ireland's holy mountain, Europe's oldest field system, and an island coastline that most visitors never reach. Mayo does not market itself the way Kerry does, and that restraint is the whole point. Come here for the landscape, not the crowds.
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.
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.
Below you'll find my complete Mayo intelligence - where to base yourself, what's genuinely worth your time, and the practical stuff that the tourism brochures conveniently skip. Everything from first-hand experience.
Where is County Mayo?
Signature Destinations
The places that make Mayo worth the drive. Arranged by genuine impact, not alphabetical order.
Island Full guide Achill Island
Ireland's largest island, connected to the mainland by a bridge. Deserted villages, Atlantic beaches that would not look out of place in the Caribbean on the right day, and Keem Bay - regularly listed among the most beautiful beaches in Europe. The Great Western Greenway cycle path ends here. Achill feels like the edge of Europe because it very nearly is.
Mountain Full guide Croagh Patrick
Ireland's holy mountain and the country's most famous pilgrimage. The climb takes about two hours up and ninety minutes down. The path is rocky and steep near the summit - proper shoes, not sandals. The views over Clew Bay from the top are extraordinary on a clear day. On Reek Sunday in July, tens of thousands climb it - some barefoot.
Coastal Full guide Clew Bay
A bay with 365 islands - one for every day of the year, according to local tradition. Dorinish was briefly owned by John Lennon. The views from the Westport side or from the slopes of Croagh Patrick are among the best coastal panoramas in Ireland. Kayaking and island-hopping tours run from Westport Quay in summer.
Heritage Full guide Ceide Fields
The oldest known field system in the world - 5,500 years old, preserved under blanket bog on the north Mayo coast. Stone walls, farm enclosures, and tombs that predate the Egyptian pyramids. The visitor centre, perched on the cliff edge, is a striking piece of architecture. This is not a flashy attraction, but if landscape history interests you even slightly, it is unmissable.
Town Full guide Westport
A Georgian planned town designed by James Wyatt, with a tree-lined mall, an octagonal town centre, and a waterfront at Westport Quay. Regularly voted Ireland's best place to live and the tidiest town. Matt Molloy's pub - owned by the Chieftains flautist - is the trad music venue. Excellent restaurants for a town this size.
Cycle Trail Full guide Great Western Greenway
A 42-kilometre off-road cycling and walking trail from Westport to Achill, following the route of an old railway line. Flat, scenic, and suitable for all fitness levels. Bike hire is available at both ends and at points along the way. One of the best greenways in Ireland - and given the competition, that is saying something.
Where to Base Yourself
Donegal is big. Where you sleep determines what you can reasonably see. Choose based on what matters to you.
Westport
The best base in Mayo and one of the best small towns in Ireland. Good hotels, excellent restaurants, and a genuine atmosphere that is not manufactured for tourists. Croagh Patrick is fifteen minutes away, Clew Bay is on the doorstep, and the greenway starts here. If you only have one base in Mayo, this is it.
Achill Island
Stay on Achill if the island itself is your priority rather than a day trip. Keel and Dugort have the most accommodation options. The island slows you down in a way that a day trip does not allow - the beaches and deserted villages deserve unhurried time. Limited restaurant options, so self-catering works well.
Mulranny
A small village between Westport and Achill, sitting on the greenway route with views across Clew Bay. The Mulranny Park Hotel is one of the best in the county. Quieter than Westport and less remote than Achill - a good middle ground if you want peace without isolation.
Ballina
The largest town in north Mayo and the practical base for Ceide Fields, the north coast, and Killala Bay. Less charming than Westport but functional, with decent hotels and a strong angling tradition - the River Moy is one of the best salmon rivers in Europe. Belleek Castle on the edge of town is worth a look.
Getting There & Around
Ireland West Airport Knock (NOC)
Mayo's own airport, built on the initiative of a local priest in the 1980s and still defying expectations. Ryanair flies to London Stansted, Liverpool, and several European cities. Aer Lingus has a Dublin route. Forty-five minutes to Westport by car. Car hire available at the terminal.
From Dublin
About 3.5 hours via the M4 and N5 through Longford and Castlebar. The road is good but not motorway the entire way - the N5 narrows west of Longford. Alternatively, go via Galway on the M6 and up from there, which adds thirty minutes but is a better road.
From Galway
About 1.5 hours to Westport via the N17 and N5. A straightforward drive through south Mayo. If you are doing the Wild Atlantic Way northbound from Galway, Mayo is the natural next section.
By Train
Irish Rail runs Dublin to Westport three to four times daily, about 3 hours 20 minutes via Athlone. The Westport station is a short walk from the town centre. One of the longer Irish rail journeys but a pleasant one - the last stretch through Clew Bay is scenic.
By Bus
Bus Eireann runs Dublin to Westport and Ballina. Local Link services connect smaller towns but are infrequent. As with most of the west, a car is essential for exploring beyond the main towns. The greenway is the exception - bikes work better than cars for that stretch.
When to Visit
May through September all work well, and Mayo has five green months because it simply does not get the crowds that Kerry or Galway do. July and August are busy by Mayo standards, which means you might share Keem Bay with twenty people instead of having it to yourself. Reek Sunday in late July brings pilgrims to Croagh Patrick in enormous numbers - avoid that weekend unless climbing is the point of your trip.
Where to Stay
Westport has the widest choice and the best standard. Achill and the north coast are quieter with smaller options. Mayo accommodation is noticeably better value than the counties to the south.
Mulranny Park Hotel, Mulranny, Clew Bay
A beautifully restored railway hotel on the edge of Clew Bay, sitting right on the Great Western Greenway. The views are spectacular, the spa is excellent, and the location splits the difference perfectly between Westport and Achill. If you want to wake up to Atlantic light without sacrificing comfort, this is the one.
Hotels
Westport has the best range - several good four-stars and a few boutique options. Achill and the north coast are guesthouses and smaller hotels. Knock has airport hotels if you need one.
B&Bs
Good B&B options across the county, particularly along the greenway route. Achill has some excellent ones with sea views. Standards are generally high and prices are lower than the more tourist-heavy counties south of here.
Self-catering
Achill Island and the coast around Mulranny are well suited to self-catering. Good for families and longer stays. Prices are noticeably lower than equivalent properties in Kerry or West Cork.
Finding Your Mayo Roots
Mayo was devastated by the Famine more than almost any other county. The population dropped from nearly 400,000 in 1841 to under 200,000 by 1901, and it has never recovered - today it is around 130,000. The west of the county was particularly hard hit, and the deserted villages on Achill Island are a visible reminder. The diaspora spread heavily to Cleveland, Ohio, and to the industrial cities of England. If your surname is Walsh, Gallagher, Moran, Gibbons, or Durkan, Mayo is where the search likely starts.
