Casla – Gaeltacht village, Connemara

Overview

Casla has been the home of RTÉ Raidió na Gaeltachta since the station first broadcast on 2 April 1972, and the Irish-language service is still the busiest thing in the village. This is a working Gaeltacht settlement on the R336 between Indreabhán and An Cheathrú Rua, where Irish is the language of the shop and the school rather than a heritage exhibit. Most people pass through on the way to the Aran Islands ferry at Rossaveal. If you have an afternoon, the one thing worth stopping for is the Seana Mhach bog trails just outside the village.

The name, and the Costelloe question

The Irish name is usually read as a twisting creek or a sea inlet, though it’s also tied to the old gCaislé sept that held this stretch of coast toward Carraroe. The English name, Costelloe, stayed the official one until it was replaced by Casla under the Official Languages Act 2003. You’ll still meet Costelloe on older maps and on the local post office.

Costelloe Lodge

Above the village sits Costelloe Lodge, an Arts and Crafts house by the architect Edwin Lutyens, with a garden laid out by his long-time collaborator Gertrude Jekyll. Its owner is the reason it’s remembered: J. Bruce Ismay, chairman of the White Star Line, who survived the sinking of the Titanic in 1912 and was ostracised for it. He bought the original fishing lodge here the following year; after it was burnt out in an IRA attack in 1922, Lutyens rebuilt the house in 1925. It remains a private, protected structure and is still lived in, so there’s no public access. The best you’ll get is a glimpse from the road.

RTÉ Raidió na Gaeltachta

The station grew out of a long civil-rights campaign by Gaeltacht communities for Irish-language broadcasting. It began with a couple of hours a day in 1972 and now runs around the clock, carrying news, sport, trad sessions and talk entirely in Irish. The studios are a working newsroom, not a visitor centre, so there’s nothing to tour. Tune the car radio to it as you drive the coast, though, and you’ll hear the place better than any plaque would tell you.

Seana Mhach bog trails

The trailheads are 1.3 km from the village, with parking at each. Four waymarked routes cross the blanket bog, all fairly gentle underfoot, with views over Loch Ghleann Mhac Muirinn, the Maamturks and Casla Bay. The bog is winter feeding ground for Greenland white-fronted geese and breeding ground for golden plover, so keep dogs close and stay on the paths.

The routes are shared-use, so cyclists should give way to walkers on the narrow sections, and Leave No Trace matters more than usual on ground this fragile.

Fishing and the strand

Casla Bay and its feeder rivers are known locally for salmon and sea trout; the season and the runs are worth asking a local guide about before you commit a day to it. West at An Cheathrú Rua, Trá an Dóilín – the Coral Strand – is made not of sand but of maërl, bleached coralline algae, and it’s a short drive on if you want a swim.

Getting there and practical details

• Public transport: Bus Éireann route 424 from Galway City runs roughly hourly, takes about an hour, and stops in the village.
• Parking: Free on-street, plus car parks at both bog-trail heads.
• Food: Cooke’s Caife Casla (also called the Courthouse Café) is in Derrynea, about 2 km from the bog trails – open Thursday to Tuesday, 9am–4pm, closed Wednesdays.
• Amenities: A post office and a small shop in the village.
• Best time: The trails are open year-round, but March to October gives the steadier weather.

Nearby

An Spidéal is a livelier Gaeltacht village back toward Galway, with pubs, an Irish-language summer college and craft workshops. Ballynakill Bay up the Connemara coast is a quieter harbour for a walk. West of Casla the road runs on to the Aran Islands ferry at Rossaveal and, further out, to Clifden.
