Three days on Mayo and Achill Island — the wildest west
Westport for the seafood, Castlebar for the GAA, Achill Island for the cliffs and sea swims. Off-grid by design, and walkable.
Mayo is Connemara's bigger, emptier neighbour to the north. Westport is the Georgian set piece; Achill Island is the dramatic offshore base. The two together are a three-night itinerary that gets you the most photogenic stretch of the Atlantic without leaving County Mayo.
This is a slow trip. The whole point is the rhythm. Do not try to add Connemara to the front or Sligo to the back — both are separate itineraries on this site.
Carbon math, up front. Every IMPT hotel booking retires one tonne of UN-verified CO₂ on-chain — roughly 28× the per-night footprint of a hotel stay.
The route at a glance
- Day 1–2: Westport — 2 nights
- Day 3–4: Achill Island — 1 night
Getting around: Train Dublin → Westport (3h 30m direct); hire a car at Westport rail station for the Achill leg
Day 1–2 Westport — 2 nights
Train Dublin Heuston → Westport is 3h 30m direct (one of the country's longer inter-city routes). Westport rail station is a 10-minute walk from the town centre via the Mall, the Georgian boulevard James Wyatt designed in 1780.
Morning
Walk the Westport Greenway out of town — flat, former rail line, follow it as far as the next coffee stop or all the way to Newport (10km) and bus back. The town's Georgian Mall is the prettiest urban set piece in the west.
The walk worth doing
Croagh Patrick — Ireland's holy mountain, 7km up-and-down, 2-3 hours for a fit walker, harder than it looks because of the loose scree near the summit. Best on a clear morning; the views back over Clew Bay and its 365 islands are the headline. Reek Sunday (last Sunday in July) is a different beast — 30,000 pilgrims, avoid.
Where to eat
An Port Mór for the formal dinner (Galway oysters, west-coast lamb, properly excellent); Sage on High Street for the casual; Matt Molloy's pub (owned by the Chieftains' flute player) for the trad session — every night, no cover, packed by 10pm. The Tavern in Murrisk (at the foot of Croagh Patrick) is the post-climb pub.
Day-trip from here
Clew Bay islands — boat tour from Westport quay, 90 minutes around the bay with stops at the inhabited islands. Or Knock Shrine (35km east) if you have a religious interest. Most travellers spend the second day in Westport itself.
Day 3–4 Achill Island — 1 night
Westport to Achill is 60km west on the N59 + R319, via the Curraun Peninsula and the Michael Davitt Bridge that connects Achill to the mainland. The drive is 90 minutes; the road is single-carriageway and slow in places. Achill (Ireland's largest island, population 2,500) has five villages — base yourself in Keel.
Morning
Keem Bay — Achill's headline beach, at the western tip of the island, EU-blue-flag, the road in is a 5km cliff-edge single-track and the descent to the beach itself is genuinely dramatic. Park at the top viewpoint and walk down; the swim is bracing but properly worth it.
The walk worth doing
Achill Head cliff walk from Keem Bay car park — 7km return along the cliff edge to the western tip, no formal path but signposted and walked-in. Allow 3 hours. Or Slievemore mountain (671m) for the longer hike via the deserted village at its southern foot.
Where to eat
The Beehive in Keel for the lunch (queue, no booking, the seafood chowder is the local headliner). Calvey's Restaurant in Keel for the formal dinner — the family have been butchers on Achill for four generations, the lamb is the thing. Lynott's Pub in Dooagh for the late drink and the deserted-village stories.
Day-trip from here
The Deserted Village at the foot of Slievemore — 80+ stone-built houses abandoned during and after the Famine, free entry, walkable in 90 minutes. Or the Atlantic Drive (a 20km signposted coastal loop on the southwest of the island).
Practical notes + how to extend
From Achill, drive back to Westport (60km, 90 minutes) for the train to Dublin, or continue north into Sligo for the Yeats country itinerary on this site. The natural three-day rhythm is two nights Westport, one night Achill; reverse it and you'll feel rushed at the start.
Mayo's restaurants close earlier than the rest of Ireland — book ahead, especially on Achill, and check seasonal opening.
The carbon mechanic — in plain English
Every hotel booked through IMPT triggers the retirement of one tonne of UN-verified CO₂ — roughly 28× the per-night footprint of a hotel stay. The room price is the standard rate. The offset is funded from IMPT's commission, recorded on-chain on Ethereum, and tied to your booking ID. For a multi-night Irish itinerary booked through IMPT, the per-traveller offset comfortably exceeds the carbon cost of the hotel-stay portion of the trip.
