What happened to the route

Achill has a bridge. That is the whole answer, and it has been the answer for well over a century. Michael Davitt opened the first crossing in 1887: a steel bowstring girder of 120 feet (37 m), pivoting on a central pier, with a roadway eight feet wide. It was built for horses. The £5,000 estimate ran over and a Fermanagh landowner, John Grey Vesey Porter, put in his own money so the design could be finished as drawn. Before it existed, islanders crossed the channel by boat or walked and rode over at low water, and the currents drowned people who misread the tide.

Two more bridges have stood on the same spot. Motor traffic wrecked the 1887 structure, Mayo County Council resolved in 1947 to demolish it, and J & C McGloughlin of Dublin finished the replacement in early 1949: the largest bridge job an Irish company had taken on to that date. By 2007 the swing mechanism was failing and holding up boats, so the council backed a third. That one opened in 2008, designed by Malachy Walsh & Partners on a Calatrava model and built by SIAC Construction. It weighs 390 tonnes and is still swung by hand. In November 2010 it refused to close for over two hours and the council sent the consultants back to find out why; it was in full service again by the end of March 2011.

So you drive, or you take the bus, or you cycle. The R319 leaves the N59 at Mulranny, runs out along the Corraun peninsula, crosses the bridge at Achill Sound and continues on to the car park at Keem Strand, 35 km end to end from the N59 at Mulranny, narrowing and twisting the whole way. Its first stretch shares an alignment with the Great Western Greenway, laid on the bed of the Westport to Achill railway that closed in 1937.

Why the search term survives is easier to explain than you would think. Achill is a genuine offshore island in the Central Statistics Office count, and in 2022 it was the most populated one in the State with 2,345 residents, ahead of Garmna, Inis Mór, Valentia and Leitir Móir. Islands in Ireland usually mean ferries. This one means a national secondary road, a regional road and a bus stop outside Sweeney’s supermarket.

When the boats run

Read from the operators’ own websites on 6 August 2026. Only three of the five publish a price and only one publishes a frequency, which tells you what kind of operation these are: small boats, run by families, answering the phone. Belmullet Boat Charters state the Blacksod to Dugort crossing as 35 minutes in their FAQ and as a 40 minute crossing two paragraphs lower on the same page; allow the longer figure. Wild West Boat Tours also run to the Inishkea islands, but their published Inishkea sailings and those of Belmullet Boat Charters (09:25 and 14:00 out, 13:20 and 17:25 back, mid-May to mid-October) leave from Blacksod, not from Achill.

Route map

The line on this map is a road, not a sailing. It runs from the Michael Davitt Bridge at Achill Sound west along the R319 to Keel, which is where the strand and most of the beds are; Bullsmouth, the pier for the one small ferry Achill really has, lies about 7 km due north of the bridge (our own calculation from the two grid references).

Use these instead

• By car from Westport: N59 north through Newport and Mulranny, then the R319 over the bridge. No ticket, no queue, no sailing to miss.
• Bus Éireann route 450, Louisburgh – Westport – Dooagh. Six buses a day onto the island Monday to Saturday, three on Sunday. Westport departures Monday to Friday are 05:30, 08:37, 10:32, 13:07, 15:12 and 17:48, reaching Achill Sound 46 to 55 minutes later and Dooagh at 06:55, 10:05, 12:08, 14:35, 16:40 and 19:15. Timetable valid from 13 April 2025. Our page on the route: Bus 450, Dooagh to Louisburgh.
• TFI Local Link Mayo route 460a, Gob an Choire (Achill Sound) – Castlebar. Five return runs a day, seven days a week, in place since 29 September 2025, when 460b replaced route 978 and 460a was added, replaced the old route 978.
• TFI Anseo, on the island itself. Ireland’s first smart demand-responsive pilot launched in Achill and Curraun on 15 July 2025, booked through an app rather than turning up at a stop, seven days a week, most trips €3 or less. It had carried over 11,000 journeys by July 2026 and has been extended past its 12-month trial, with a final report due in December 2026.
• By train, as far as the mainland. Irish Rail serves Westport and Castlebar from Dublin; the 450 continues from Westport, the 460a from Castlebar. See buses in Westport and buses in Castlebar.
• By bike. The Great Western Greenway runs traffic-free from Westport to Achill on the old railway. Achill Tourism gives it as 42 km extended to 49 km after a 5 km addition to Cashel in 2023; greenway.ie calls the whole thing 44 km and the Mulranny to Achill section 14 km. Nobody has reconciled them.

Do you need to book?

For the island itself: no. For every boat mentioned here: yes, and by phone as often as not. Achillbeg Ferry takes online bookings and recommends them in summer. Inishbiggle Ferry has a Book Now button that opens a phone number, +353 86 061 2482, and a pricing page that lists a fare but not a single sailing time. Wild West Boat Tours and Belmullet Boat Charters both work through an enquiry form or a call. TFI Anseo is booked in its own app and Achill Tourism advises at least two hours’ notice.

About the island

Achill covers about 148 km², which makes it the largest of the Irish isles, and the population has been sliding for two centuries: 2,569 in 2011, 2,440 in 2016, 2,345 in 2022. Roughly half the island, Achill Sound included, is inside the Gaeltacht, though English is what you will hear. The villages people actually stop in are Keel, Dooagh, Dooega, Dooniver, Dugort and Achill Sound.

Croaghaun, at the western end, has a summit of 688 m, and its northern flank falls to the sea as the highest sea cliffs in Ireland and the third highest in Europe. There is no road to them. You either walk up and around the mountain or you pay somebody with a boat, which is one of the very few situations on Achill where a boat is the answer to anything.

On the southern flank of Slievemore stands the deserted village, a line of unmortared stone houses running roughly a mile along an old track. Estimates of how many survive differ by source and by what you count as a building; the count runs from 80 to 100 ruined houses still standing, against 74 traceable out of the 137 recorded on the Ordnance Survey of 1838. Mayo County Council says 74 buildings out of an original 137. Its last life was as booley houses, occupied over the summer while cattle grazed the mountain, the families going back down to Dooagh for winter. The Achill Archaeological Field School excavated three of the houses there between 1991 and 2013.

Keem, at the end of the R319, holds a Blue Flag. Mayo County Council staffs it with lifeguards from noon to 18:30, weekends and bank holidays in June, every day in July and August, and then the first Saturday and Sunday of September only. Dogs are off the Blue Flag section between 12:00 and 18:30 in summer, on leads the rest of the time. From the mid-1940s the same bay was a basking shark fishery; the liver oil went into cosmetics and aviation, and the fishery closed in the 1970s when the sharks did not come back.

The Banshees of Inisherin was filmed here, and Achill Tourism publishes the trail itself, which is the only reason we will name locations: Cloughmore for JJ Devine’s pub, built by the crew and taken away again, and for the fork in the road with the Virgin Mary statue; Purteen Harbour, dressed as a portside street with a post office and O’Riordan’s shop — the cottages a facade, the shop built outright for the film; Keem Bay for Colm’s house and the last scene; Corrymore Lake for Mrs McCormick’s cottage; and St Thomas’s Church at Dugort, a working 19th-century Church of Ireland building, for the Mass scenes. The film is set on a fictional island reached by boat. The island it was shot on is reached by road.

Vehicles on board

Your car crosses the bridge. There is nothing to book, nothing to pay and no vessel involved, which is the single most useful thing on this page for anyone who arrived expecting a car ferry and a sailing schedule.

Onto the boats is another matter, and the constraint is size. The Naomh Michael at Bullsmouth is licensed for five passengers and two crew, and every passenger is handed a lifejacket before departure. Bicycles go to Inishbiggle, and the operator hires them out on the island as well. Wild West Boat Tours bar bikes and dogs from their Inishkea landings under National Parks and Wildlife Service rules, while dogs are welcome on their Croaghaun cliff run because nobody gets off. Belmullet Boat Charters take dogs on the boat but not onto Inishkea, and invite passengers to bring a bike over to Dugort.

Weather and cancellations

The Bullsmouth channel is the problem, not the open Atlantic. Mayo County Council describes it as having one of the strongest currents in Europe and states plainly that unpredictable winter currents can leave Inishbiggle inaccessible; the island has a helipad, refurbished in 2026 with State funding, for exactly that reason. Ten minutes in fair weather, and that figure is for the traditional currach. Nothing at all in the wrong weather.

Achillbeg sailings carry a standing weather permitting qualifier from the operator. Wild West Boat Tours say that when it is too rough for the Croaghaun cliffs they will run to Blacksod instead, which is an honest way of admitting the cliffs are the exposed part of the trip. The bridge has stuck too: over two hours in November 2010, and swing-gear trouble bad enough by 2007 to justify replacing the whole span.

Can you do it in a day?

Yes, comfortably, and you do not need to sail to do it. Take the 08:37 out of Westport Monday to Friday: Keel at 09:58, Dooagh at 10:05. Come back on the 16:45 from Dooagh, which puts you into Westport at 18:11. That is six hours and forty minutes on Achill on a single bus ticket. If you want the long version, the last bus leaves Dooagh at 19:20 and reaches Westport at 20:43.

Achillbeg works as a half-day from Cloughmore: ten minutes across, about two hours ashore, departures every half hour when the weather allows. Inishbiggle is a different proposition because there is no schedule to plan around. You ring the number, you agree a time, and the return is whatever you agreed. Bike hire on the island is €10 for half a day, which suits an island of twelve people.

Continuing your journey

• Bus Éireann 450 continues past Westport to Murrisk, Lecanvey and Louisburgh, which is the road to Roonagh Quay.
• From Roonagh, sailings run to Clare Island and Inishturk: see Roonagh to Clare Island and Roonagh to Inishturk. Clare Island Ferry also run Cloughmore on Achill as a charter, on demand.
• TFI Local Link 460a links Achill Sound to Castlebar five times a day, seven days a week, with connections at Castlebar to the rail station and Mayo University Hospital.
• Within Achill and Curraun, TFI Anseo replaces the walk to a bus stop with an app booking, seven days a week.

Getting to the pier

Four places matter here and only three of them are piers. None is a ferry terminal in any sense you would recognise from Rosslare. No terminal building, no check-in desk, no waiting room.

• Bullsmouth, Dooniver (53.99702, -9.92931 by the operator’s own grid reference, matched to the slipway on the L1406). This is the Achill end of the Inishbiggle boat and the island’s only berth with a regular boat to another inhabited island.
• Cé Bheag, Cloughmore, in the south-east corner, for Achillbeg. The adjacent Cloughmore pier (53.87439, -9.94826) is tagged as a ferry terminal on the map and is where Clare Island Ferry runs charters to and from Clare Island, on demand rather than to a timetable.
• Dugort pier, on the north coast under Slievemore, for the Croaghaun cliff runs and for the Blacksod boat when it lands.
• The Michael Davitt Bridge itself (53.93257, -9.92221), signposted in Irish as Droichead Mhícheál Mhic Dháibhéid. The Greenway trailhead on the Achill side sits a few hundred metres east of it.

Accessible travel

The bridge is a public road, so wheelchair access to Achill is the same question as wheelchair access to any Irish village, and Bus Éireann publishes a wheelchair-accessible routes list on its own site. Keem is the one place with a firm commitment: Mayo County Council lists disability access, parking, a car-free zone and toilets among its Blue Flag facilities.

The boats publish almost nothing, and one of them publishes a warning. Achillbeg Ferry state that the self-guided walk crosses steep, uneven, sometimes muddy ground and may not suit people with limited mobility, heart conditions or serious health issues. Inishbiggle Ferry, Wild West Boat Tours and Achill Seascape make no accessibility statement we could find; Achill Seascape do set minimum ages of 8, 10 and 12 depending on the tour. If you need step-free boarding, ring first, because none of these piers has published anything to plan around.
