Clifden has fewer sights of its own than its billing as ‘the capital of Connemara’ suggests, and that’s the point: it’s the town you sleep, eat and refuel in while the things you actually came west for sit a short drive away. With a population of around 1,250 it’s the largest town in the region by some way, set where the Owenglin River runs into Clifden Bay under the Twelve Bens. If you only do one thing, drive the Sky Road.
The Sky Road
The Sky Road is a 16 km coastal loop that climbs out of the town to the west and runs high above Clifden Bay before dropping back. On a clear day it’s one of the best short drives in the west of Ireland, taking in Streamstown Bay, the offshore islands and the open Atlantic.
One honest warning: the upper section has blind bends and no footpath, so this is a drive, not a walk. There’s a proper car park at the high viewpoint about 5.5 km out – pull in there for the views rather than stopping on the road. Go clockwise and you’ll have the light behind you for most of it.
Clifden Castle
A couple of kilometres along the Sky Road, a gateway arch leads down a rough track to Clifden Castle, the ruined Gothic Revival manor built in 1818 by John D’Arcy, the man who founded the town. The walk in passes a line of standing stones; the castle itself is roofless arches and bare walls now, atmospheric and completely unstaffed – there are no facilities.
The catch is parking: the small area by the entrance holds only three or four cars and fills up in peak season, so come early or be ready to wait. The track down is uneven, so wear something sturdier than trainers.
Marconi, Alcock and Brown
The most consequential ground around Clifden is a stretch of bog four miles (6 km) to the south, at Derrygimlagh. In 1907 Guglielmo Marconi built the first permanent transatlantic wireless telegraphy station here, a sprawling complex that employed up to 200 people relaying messages across the ocean by Morse. It was wrecked during the Civil War in 1922 and never rebuilt.
Twelve years after it opened, on 15 June 1919, the aviators John Alcock and Arthur Brown brought their Vickers Vimy down nose-first into the same bog, completing the first non-stop transatlantic flight – they mistook the soft ground for a field. A looped walking trail with interpretive boards now links the Alcock and Brown crash site and the wireless-station foundations. It’s flat but exposed and often wet underfoot.
A little history
John D’Arcy laid out the town in 1812 on an estate of more than 17,000 acres, and by the 1830s it was a working port with two churches, a courthouse and a couple of dozen pubs. In 1843 Daniel O’Connell brought one of his ‘Monster Meetings’ here, drawing a crowd put at around 100,000 to press for repeal of the Act of Union. The Famine hit hard a few years later, emptying the surrounding townlands and eventually breaking up the D’Arcy estate.
Walks and the wider region
Clifden makes its living as a base, so most of the good walking is just outside it:
- Diamond Hill – about 20 minutes away in Connemara National Park, a 7 km loop that climbs to 442 m for views over the coast, the Twelve Bens and across to Kylemore Abbey. The best half-day out from the town.
- Beach Road – a flat, easy walk down to Clifden Harbour, good for watching the boats and spotting seals in the inlet.
- Kylemore Abbey – a 19th-century castle turned Benedictine convent to the north, with Victorian walled gardens. Adult admission runs around €18, so it’s a paid day out, not a quick stop.
Practical information
- Getting there: Clifden is about 77 km (50 miles) west of Galway city on the N59. Citylink runs regular coaches from Galway, and Bus Éireann links the town toward Westport. You really want a car here – the sights are spread out and bus stops won’t get you to the Sky Road or Derrygimlagh.
- Eating: For seafood, Mitchell’s Restaurant and Off the Square on the main street are the two names that come up most; Guys Bar is the reliable family option for a pub meal.
- What’s on: The Clifden Arts Festival each September is the longest-running community arts festival in Ireland and takes over the town for a week. A newer Clifden Piano Festival launched in 2026.
- Best time: Late spring to early autumn for the daylight and the festival calendar. Whatever the month, bring waterproofs – the bog walks and the castle track turn to mud fast.
If you’ve one evening in Clifden, skip the early night: the pubs run trad sessions through the summer, and the walk back along the Sky Road approach at dusk, with the bay going silver, is the thing people remember.
