Achill Island, the short version

We keep a running list of places in Co. Mayo worth the detour. This is the Achill Island entry, with the practical bits up front.

Achill sits off the west coast of Ireland. It covers roughly 147 square kilometres. A bridge over Achill Sound has linked it to the mainland since 1887. The current span, the Michael Davitt Bridge, opened in 2008. Before that, boats were the only way in. That isolation still shapes the island's feel. A few thousand people live here. It is a working place, not just a tourist stop. Farms, small shops, and a tight-knit community define daily life.

The coastline draws most visitors. The Croaghaun headland on the northwest side forms a long cliff wall. From there, you can see the mainland and the Twelve Bens. Keem Bay, on the west side, has black pebbles. A sea stack known as "Finn's Boot" stands off its end. The Dugort peninsula to the south is quieter. It offers small coves and open headland. Dooagh Lagoon, on the south coast, is flat and sheltered. Islanders have farmed this land for generations.

The Duggan's Rocks lighthouse sits off the Dugort coast. It carries one of the island's most famous stories. Local tradition speaks of a keeper and his son. A storm in the 1930s took the young keeper. The full facts are unclear, but the story remains part of local memory. Standing there, the sea feels close. The place and the tale are tightly bound. Few spots on the island match that connection.

Practical. A full day is not enough; allow two or three days. Free to explore; a small charge at some coastal car parks. Best time: late summer for the heather colour; any calm day for the coast. The island is best explored by car. The ground on the headlands is rough and exposed in places; wear proper footwear and check the weather. Getting there: by car: the Michael Davitt Bridge crosses Achill Sound, landing at Keel on the island’s west end; from Sligo allow about 1h45, from Galway about 2h15. The bridge is a single carriageway and can be busy in high season

Where to stay. Keel (at the bridge end) — Where the bridge lands; surf beaches and the Duggan’s Rocks coast nearby. Islandbridge (25 min by car) — The west side’s main village — shops, pubs, the Dooagh Lagoon beaches.

Nearby, if the day runs long. Croagh Patrick (Croagh Patrick, a 764-metre peak near Murrisk, is a historic site where St Patrick fasted.);

Keep it in Saved if the trip is still a while off — the place page will tell you when the practical details have been re-checked.
