Overview
Killary Harbour is Ireland’s only true glacial fjord, a 16km inlet up to 45m deep that cuts southwest from the Atlantic into the heart of Connemara. It forms a natural border between County Galway and County Mayo, flanked by some of the west coast’s most imposing peaks: Mweelrea (817m), the Maumturk range and the Twelve Bens. The Irish name, An Caoláire Rua, means ‘the narrow red sea-inlet’ – caol for the narrow inlet, rua for red, a nod either to seaweed-streaked water or the reddish cliffs. Sixteenth-century maps called it ‘The Red Bay’, or ‘Kelariroeh’.
If you only do one thing here, take the boat. The fjord’s best views are from the water, well off any road. Just come prepared: this is one of the wettest corners of Ireland, where the mountains wring the rain out of the Atlantic, so pack for weather even in July.
History & Geology
Killary’s shape is the direct work of the last Ice Age. A glacier ground out a steep-sided valley over thousands of years, and when sea levels rose the basin flooded to leave a deep, narrow inlet – its depth, length and sheer cliffs are what mark it as a true fjord rather than a shallow coastal inlet. Recent excavation near Leenane turned up a ring-barrow burial mound above the water, a sign the fjord drew people to live and bury their dead here in prehistory.
The 19th century left its own scars. During the Great Famine, thousands of labourers were set to work on relief projects to stave off starvation. Their work produced the ‘Green Road’, a rough track along the northern shore that walkers still follow today – a sobering thread of history under some sweeping views.
Exploring the Fjord
Catamaran Cruises
The most efficient way to see the fjord is aboard the Connemara Lady, a 90-minute catamaran tour. It departs not from Leenane itself but from Nancy’s Point, about 2km west of the village on the southern shore, cruising west for around 45 minutes to Fox Rock (InishBarna) before turning back. Bottlenose dolphins sometimes run alongside the bow in the warmer months. The boat is wheelchair-accessible and has a café and licensed bar, and pets are allowed on the outside decks. Tours run weekends only in winter, scaling up to as many as three departures a day at the height of summer; book online in advance for the busy months.
Adventure Activities
For a hands-on day, the Killary Adventure Centre, on the N59 near the head of the fjord, runs kayaking, surfing, coasteering, gorge walking, water-skiing, diving and high-rope courses, plus its muddy ‘turf warrior’ challenge. Guided sea-kayak trips explore sheltered coves and the calmer upper reaches, getting you close to the cliffs and bird colonies without any engine noise.
Aasleagh Falls
At the fjord’s head, the River Erriff spills over Aasleagh Falls before reaching the water. It’s not a tall drop, but it spreads wide across the river and turns to a roar after rain. You can see it from the boat, or reach it on a short, well-marked path from the road near Leenane.
Walking the Shorelines
Killary has two shoreline walks, both rooted in 1840s famine relief.
- The Green Road (north shore): a 9km rough track along the original labourer route, with panoramic fjord views, passing mussel farms and terrain that wants sturdy footwear. It ends near Little Killary.
- South-side famine walk: starting from Leenane, this flatter 9km out-and-back traces the opposite bank, with uninterrupted views of the Maumturks and Mweelrea across the water. It passes abandoned stone cottages and is manageable for families in two to three hours.
Wildlife & Local Experiences
The sheltered water supports a rich mix of life. Grey and harbour seals haul out on rocky ledges year-round; bottlenose dolphins are most active from late spring to early autumn. Winter brings barnacle geese, whooper swans and tufted ducks, with waders arriving in spring. The steep banks carry Atlantic oak woodland, ferns and mosses that thrive in the damp maritime air.
Beyond the water, Leenane and its surroundings reward a wander:
- Leenane village: the settlement at the fjord’s head, known for its part in the 1989 film The Field. Gaynor’s Bar keeps a peat fire going, pours pints of Guinness and serves hearty food, with a ‘fisherman’s plate’ during mussel season; the Blackberry Café does soup and homemade scones.
- Sheep and Wool Centre: in Leenane, covering traditional mountain sheep farming and weaving, with a Famine Memorial nearby that marks the region’s losses.
- Mussels straight from the fjord: the mussels and clams grown in Killary are sold at Westport Country Market on Thursday mornings.
- Delphi Valley: a seven-minute drive inland, holding three glacial lakes – Glencullen, Doolough and Finnlough – that drain into the fjord.
Practical Information
Getting There & Parking
The fjord is reached by car on the N59 between Galway and Clifden, at Leenane. Buses run from Galway and Clifden to the village. The clearest place to stop for the view is the large lay-by on the N59 about 200m past the Killary Adventure Centre, on the left as you come from Clifden – the whole fjord opens up below the road. There’s also parking in Leenane village. The nearest airport is Ireland West (Knock), roughly an hour and a half away by road.
When to Go
Tours and boat trips run from spring through mid-October, with the fullest schedule in July and August; winter sailings are weekends only, weather permitting. Wild camping is tolerated near Rosroe Pier, provided you respect the land and leave no trace. The annual Great Fjord Swim brings open-water swimmers to the harbour each year.
Accessibility & Family Tips
The Leenane visitor centre and the catamaran boarding ramp are wheelchair-accessible. The Green Road is a rough, uneven track best suited to boots and moderate fitness; the south-side walk is flatter and better for families with older children, though pushchairs aren’t recommended on either. Leashed dogs are welcome on both walks and on the boat’s outer decks.
Fishing & Angling
The Erriff and Delphi rivers, which feed the fjord, hold strong runs of salmon and sea trout from late spring to early autumn. Anglers need a local permit, available from the Leenane tourist office or visitor centre, before fishing.
Nearby Highlights
Killary pairs well with the wider region. Kylemore Abbey and Connemara National Park are both under 30 minutes away, and the Sky Road near Clifden gives elevated views of the Atlantic coast – easily strung together into a single Wild Atlantic Way day.
For the free version of the boat’s best view, pull in at that marked lay-by on the N59 just past the Killary Adventure Centre. It costs nothing, and the fjord looks every bit as good from up there.
