Overview
Casla (Irish: Costelloe) is a small Gaeltacht village perched on the edge of Clynagh Bay in western County Galway. Situated on the R336, the settlement lies between Indreabhán and An Cheathrú Rua and forms part of the Wild Atlantic Way, offering sweeping views of the Twelve Bens, the Maamturks and the glittering waters of Casla Bay. The village is a hub for Irish‑language broadcasting, home to the headquarters of RTÉ Raidió na Gaeltachta, and a gateway to some of Connemara’s most rewarding outdoor experiences. Nearby Gaeltacht community of An Spidéal provides additional cultural attractions.
History
The name Casla is thought to derive from the Irish word for a “twisting creek” or “inlet from the sea”. Archaeological tradition links the name to the ancient gCaislé sept that once occupied the area. In the early 20th century the village was touched by the turbulence of the Irish Civil War; a fishing lodge was burnt down in 1922 and later replaced by Costelloe Lodge, a striking 1925 house designed by Sir Edwin Lutyens with gardens by Gertrude Jekyll. The lodge became the residence of J. Bruce Ismay, the former chairman of the White Star Line, whose presence sparked controversy after the Titanic disaster. Literary references also echo through Casla – Olivia Manning’s novel The Wind Changes mentions the village pier as a landing point for 1916 Easter Rising leaders.
What to See & Do
RTÉ Raidió na Gaeltachta
A visit to the RTÉ Raidió na Gaeltachta headquarters offers a glimpse into Ireland’s living linguistic heritage. Guided tours, when available, showcase the studios where Irish‑language programmes are produced for a national audience.
Costelloe Lodge and Gardens
Although the interior of Costelloe Lodge is private, the surrounding gardens designed by Gertrude Jekyll can be admired from the public footpaths that wind around the estate. The formal planting and sweeping vistas over the bay illustrate the collaboration of two of Britain and Ireland’s most celebrated early‑20th‑century designers.
Seana Mhach Bog Trails
A newly opened network of looped and linear trails skirts the village, inviting walkers and cyclists to explore one of Ireland’s most biodiverse blanket‑bog landscapes. The trails reveal habitats that support the Greenland White‑fronted Goose in winter and the Golden Plover during the breeding season. Anglers will recognise the area as part of the Casla Bay catchment, famed for salmon and sea‑trout fishing.

Both the southern and northern trailheads sit just 1.3 km from the village centre and are reachable on foot or via Bus Éireann route 424. Parking is provided at each entrance, and the nearby village offers cafés and small shops for a well‑earned break. For cyclists, the longer loops provide gentle gradients and spectacular panoramas of the Maamturks and the Twelve Bens.
Fishing and Water Activities
Casla Bay and the surrounding rivers are celebrated for their salmon and sea‑trout runs. Local anglers often launch from the pier or from the sheltered coves that dot the coastline. The bay’s clear waters also make it a pleasant spot for swimming in summer, while the nearby Trá an Dóilín (Coral Strand) offers a sandy beach framed by dramatic cliffs.
EuroVelo 1 – The Atlantic Coast Route
The long‑distance EuroVelo 1 cycle route passes through Casla on its Costello‑to-Clifden section. Cyclists can download the GPX file from the EuroVelo website and follow a low‑traffic road that hugs the Atlantic coastline, providing uninterrupted sea views and opportunities to stop at the village’s cafés.
Practical Information
Casla is accessible by road via the R336 and is served by Bus Éireann route 424, which links the village with Galway City. The nearest train station is in Galway, about 45 km to the south. For those driving, the village benefits from free on‑street parking and dedicated car parks at both Seana Mhach trailheads.
The village’s main amenities include a post office, a small grocery, and a handful of eateries. Cooke’s Caife Casla in nearby Derrynea (approximately 2 km from the southern trailhead) is a popular spot for a hearty Irish breakfast or a light lunch after a walk. Internet connectivity is generally good, and the RTÉ Raidió na Gaeltachta office provides free Wi‑Fi in its public reception area.
While there are no formal opening hours for the village itself, the Seana Mhach Bog Trails are open year‑round and are best explored between March and October when the bog flora is at its most vibrant. The trails are waymarked and suitable for walkers of moderate fitness; cyclists should be comfortable with mixed‑surface paths.
