Overview
Casla (officially renamed from Costelloe in 2003) sits on the R336 coast road in western County Galway, perched between the villages of Indreabhán and An Cheathrú Rua. As a designated Gaeltacht settlement, Irish remains the living community language here, heard in local shops, schools, and the streets. The village is a gateway to some of Connemara’s most striking landscapes, with uninterrupted views across Clynagh Bay toward the Maamturk Mountains and the jagged peaks of the Twelve Bens. From tracing Ireland’s broadcasting history to cycling through ancient blanket bogs or pausing to watch the Atlantic weather roll in, Casla offers a grounded, authentic slice of west Galway life.
History & Name Origins
The name Casla is traditionally interpreted as meaning a “twisting creek” or “sea inlet,” though etymologists also link it to the ancient gCaislé sept that once occupied the coastline between here and Carraroe. The area’s history is woven into Ireland’s modern struggle for independence. During the 1922 Irish Civil War, a local fishing lodge was destroyed, prompting the construction of a replacement estate that would soon attract international attention. Literary history also touches the village: Olivia Manning’s 1937 novel The Wind Changes, set during the War of Independence in 1921, features a fictional plot point where the last remaining leader of the 1916 Easter Rising is expected to make a clandestine landing at the Costelloe pier.
RTÉ Raidió na Gaeltachta
Casla is best known as the headquarters of RTÉ Raidió na Gaeltachta, Ireland’s dedicated Irish-language radio service. The station began broadcasting on 2 April 1972, fulfilling decades of advocacy by Gaeltacht civil rights groups and language activists who demanded a media platform for Irish speakers. What started as a limited two-hour daily service has grown into a 24-hour national broadcaster, producing news, sports commentary, traditional music sessions, and contemporary cultural programming entirely in Irish. While the studios are primarily operational spaces rather than a public museum, the station’s presence is a constant reminder of the village’s role in preserving and modernising Gaeilge. Visitors can often hear the broadcast on local FM frequencies, and the station’s commitment to Irish-language journalism and music remains a cornerstone of regional identity.
Costelloe Lodge & Gardens
Rising above the village is Costelloe Lodge, an eight-bedroom Edwardian country house designed in 1925 by the architect Sir Edwin Lutyens. The estate was commissioned by J. Bruce Ismay, the former chairman of the White Star Line, following the burning of his original fishing lodge during the Civil War. Ismay’s tenure here was marked by controversy due to his survival of the Titanic sinking, but the lodge itself remains a significant architectural landmark. The surrounding gardens were laid out by Gertrude Jekyll, one of the most influential horticulturists of the early 20th century. While the house interior operates as a private retreat and events venue, the formal planting schemes and terraced lawns overlooking the Casla River can be admired from the public footpaths that border the estate.
Seana Mhach Bog Trails
The standout outdoor attraction near Casla is the Seana Mhach Bog Trails, a network of waymarked looped and linear routes designed for walkers and cyclists. The trails traverse one of Ireland’s most biodiverse blanket-bog landscapes, offering sweeping vistas of Loch Ghleann Mhac Muirinn, the Maamturks, and Casla Bay. The area supports nationally important habitats, including wintering grounds for the Greenland White-fronted Goose and nesting sites for the Golden Plover. In spring, visitors may still observe the traditional practice of hand peat-cutting, a living heritage that shapes the local terrain.
The trail system features four distinct routes, colour-coded and graded for moderate fitness:
| Trail | Distance | Grade | Elevation | Est. Walking Time |
|---|---|---|---|---|
| Bealach Sheana Mhach | 7.0 km | Moderate (Purple) | 37 m | 2.0–2.5 hrs |
| Lúibín Loch Bhárr an tSrutháin | 2.69 km | Moderate (Green) | 27 m | 0.75–1.0 hrs |
| Lúibín Loch na mBruaichíní | 3.35 km | Moderate (Blue) | 29 m | 0.75–1.0 hrs |
| Lúibín na Spéartha Dorcha | 6.35 km | Moderate (Orange) | 39 m | 2.0–2.5 hrs |
Trailheads are located at the northern and southern ends of the network, just 1.3 km from the village centre. Dedicated parking is available at both entrances. The routes are shared-use paths, so cyclists should yield to walkers on narrower sections. Following Leave No Trace principles is essential to protect the fragile bog ecosystem and local wildlife.
Fishing & Water Activities
Casla Bay and its tributary rivers are widely regarded as some of Connemara’s finest waters for salmon and sea trout angling. The catchment area’s clear, peat-fed streams and sheltered coastal inlets attract experienced fly fishers and boat anglers throughout the season. In summer, the bay’s calm waters are suitable for swimming, while the nearby Trá an Dóilín (Coral Strand) offers a Blue Flag beach known for its distinctive white coral sand and clear waters. Local fishing guides and charter operators in the area can provide equipment hire and advice on seasonal runs.
Getting There & Practical Information
Casla is easily reached via the R336 coastal road, part of the Wild Atlantic Way. Key practical details for visitors include:
- Public transport: Bus Éireann route 424 runs between Galway City and Carraroe, stopping directly in the village.
- Parking: Free on-street parking is available in Casla, with additional dedicated car parks at both bog trail entrances.

- Best time to visit: The bog trails are open year-round, but March to October offers the most reliable weather and colourful bog flora.
Nearby Attractions
A short drive inland brings you to An Spidéal, another lively Gaeltacht village on Galway Bay known for its traditional music sessions, summer Irish-language college, and craft workshops.
