Key Information

Killary Harbour or Killary Fjord (Irish: An Caoláire Rua, meaning 'the red fjord')[1] is a fjord or fjard on the west coast of Ireland, in northern Connemara. To its north is County Mayo and the mountains of Mweelrea and Ben Gorm; to its south is County Galway and the Maumturk Mountains.

Structure

[edit]

The flooded valley is 16 kilometres (10 mi) long, and in the centre over 42–45 metres (138–148 ft) deep; the sea bed is higher outside its mouth, as is normal for a fjord.[2] For nearly half its length, it runs south east from the Atlantic, and then it crooks and runs directly east. It narrows after the infall of the Bundorragha River, and then widens in the vicinity of Leenane. In its innermost section, it becomes very narrow, widens where a small river comes in from the south, and ends with the line of the valley of the River Erriff. The river itself does not enter on the main line of the Harbour but curves northwards and then runs south into the inlet.

The northern shore rises sharply to a much greater extent than the southern, which is in places merely hilly. On that northern shore lies the mountain Mweelrea, Connacht's highest, rising to 814 metres (2,670 ft), and the sides of which fall steeply into the inlet, with Uggool Beach at its western edge. To the south rise the Maumturk Mountains and the Twelve Bens. The island of Inishbarna (Inis Bearna or Inis Barna) is situated at the mouth of Killary Harbour.[3] The area contains some of Ireland's most dramatic scenery.

Nature

[edit]

Killary has for centuries been known as a fjord[4][5][2] - "the only fjord in Ireland"[6] or sometimes "one of 2–4 fjord-type inlets" on the island.[7] There has been argument in at least one peer-reviewed paper that it is in fact one of three glacial fjards (shallower than true fjords) in Ireland, the others being Lough Swilly and Carlingford Lough.[8] A key point in such argument is that it lacks extensive steep cliff walls, but this does not take full account of the underwater sides of the valley, and the shape of its bed. The matter was considered in a dedicated peer-reviewed paper, "An Oceanographical Survey of Killary Harbour...," that concluded that Killary was a fjord.[9][10] The landform was shaped by a massive glacier, carving its way from the land to the Atlantic Ocean.

Rivers and streams

[edit]

The Erriff River flows into the head of the inlet, and multiple smaller rivers and streams enter along its length. These include the Bunanakee River flowing across Uggool Beach near the mouth, the Bundorragha River (with tributaries including the Owennaglogh, Sruhaunboy, Owengar from Finlough to Doolough, Glenummera), and the Lahill River at Leenaun, and others. On the Erriff River just above Killary are the Aasleagh Falls.

Flora and fauna

[edit]

The Harbour is a sheltered waterway, and otter are sometimes found. Both grey and harbour seals,[11] and dolphins, and sharks,[12] can be sighted, and on at least one occasion there was a bearded seal sighting.[13] Salmon and sea trout are also encountered, and provide food for the seals. Some bird species frequenting the area include mallard duck and other breeds of duck, grey heron, barnacle goose, mute swan and whooper swan, and plover.

Marine zoology study

[edit]

The sea-loch has attracted naturalists studying marine zoology. Irish naturalist, writer, and historian Emily Lawless, in an essay from 1898, recalled renting a cottage by the 'Greater Killary' on a research trip, in order to "extract . . . every wriggling, writhing, prickly, slimy, glassy . . . creature" from its waters, to document and analyse them.[14]

Settlement

[edit]

There are today two minor settlements nearby. On the southern side near the mouth of the Harbour lies the hamlet of Rosroe, between Killary and Little Killary, while the village of Leenaun (Leenane) lies two thirds of the length of the valley inland to the east. Leenaun has a hotel and guesthouses and there are one more of each at Delphi, in a valley running down to Killary Harbour from the north.

Close to Rosroe there is an old building which now houses a hostel. This building was formerly a modest house which was used by Ludwig Wittgenstein, the famous philosopher, as a quiet place to write shortly after World War II. A plaque acknowledging this was unveiled by President Mary Robinson in 1993.

Near to Rosroe begins the so-called Green Road, a rough roadway running along the side of the valley back east towards Leenaun. It stretches for approximately nine kilometres and was part of the famine relief program during the 19th century. This road passes the last remnants of the hamlet of Foher, which disappeared in the period of the Great Famine.

A second "lost village" – Uggool – lay just north-east of the mouth of the inlet, above Uggool Beach.

Economy

[edit]

Killary draws considerable tourist traffic and a catamaran service run by "Killary Fjord Boat Tours"[15] from April to mid-October is a notable local employer.[citation needed] Aquaculture is also important locally with a salmon farm based at Rosroe while mussel rafts are a common sight further to the east.[16]

from Grokipedia
Killary Harbour, known in Irish as An Caoláire Rua (meaning "narrow red inlet"), is a glacial on the west coast of that forms a between to the south and to the north, in the scenic region of . Stretching approximately 16 kilometres in length and reaching depths of up to 45 metres, it is one of 's three glacial fjords—alongside and Carlingford Lough—and is often described as the country's only true due to its drowned by post-glacial sea-level rise. Geologically, Killary Harbour was sculpted by glacial erosion during the Pleistocene epoch, with its steep, mountainous sides rising sharply from the water and featuring ancient and rocks along the shores. The opens to the Atlantic Ocean between Aughrus Point and Roonah Head, narrowing to widths of 200–800 metres and providing sheltered waters ideal for marine activities, though strong westerly winds can affect navigation. Ecologically, it supports diverse , including otters, seals, dolphins, and seabirds such as fulmars, and serves as a breeding ground for and . In November 2024, approximately 7,000–8,000 farmed escaped from a damaged aquaculture pen, likely consumed by local seals and dolphins, highlighting interactions between farming and . Economically, the harbour has been significant for since the early 1970s, when farming began due to the nutrient-rich waters from surrounding ; it hosts farms at Rosroe and extensive rafts, making it a key site for sustainable production with a focus on multi-species integrated systems. Historically, the area around Leenane village at its head was involved in 19th-century relief efforts, including road construction along its shores, and it has long been a refuge for local clans like the O'Flahertys, isolated by the rugged terrain. In modern times, Killary Harbour attracts tourists for tours, , and amid the nearby mountains and Valley, highlighting its role as a cornerstone of Ireland's .

Geography

Location and Extent

Killary Harbour is situated on the west coast of , forming a between to the south and to the north. Its central coordinates are approximately 53°37′N 9°48′W. This position places it within the rugged landscapes of northwestern , where it serves as a significant geographical feature separating the two counties along its 16-kilometer extent. The inlet stretches 16 kilometers (9.9 miles) eastward from the Atlantic Ocean at its mouth near Rosroe to its head at Aasleagh Falls. Its width varies along its length, generally ranging from approximately 200 to over 900 meters, with the harbour narrowing in its middle section before widening again near the village of Leenane. This configuration contributes to its fjord-like character, creating a dramatic, enclosed . The surrounding topography is dominated by steep mountains on both sides. To the south in lie the Maumturk Mountains and the range, while to the north in rises , the highest peak in at 814 meters. These elevated terrains frame the harbour, enhancing its scenic isolation and depth. Killary Harbour lies at the heart of the region, a culturally and naturally distinctive area known for its wild, mountainous terrain. It is a key landmark along the Wild Atlantic Way, Ireland's renowned coastal driving route that highlights dramatic seascapes and heritage sites.

Geological Formation

Killary Harbour originated from glacial activity during the last Ice Age, when advancing glaciers carved a characteristic U-shaped valley through the underlying bedrock, deepening and widening it over millennia. This erosive process was driven by the movement of ice sheets flowing from southeast to northwest across the region, leaving behind prominent glacial features such as corries, arêtes, hanging valleys, moraines, and erratic boulders. Following the retreat of the glaciers approximately 10,000 years ago, post-glacial isostatic rebound and rising sea levels led to the inundation of the valley by the Atlantic Ocean, transforming it into a submerged inlet. The harbour's depth profile reflects its glacial heritage, with an average depth of approximately 20 meters and a maximum depth of 45 meters in the central basin, though shallower areas occur near the mouth and head. The entrance features a relatively shallow sill approximately 10-15 m deep. This configuration, including the sill, has sparked debate over its classification as a true versus a fjard—a broader, shallower drowned glacial with less steep sides. A 1986 oceanographical survey concluded that Killary qualifies as a due to its deep basin exceeding the depth of the adjacent coastal shelf and the presence of a pronounced glacial , despite the sill's modest height. The surrounding geology consists primarily of metasediments, including siliceous grits, siltstones, and mudstones that form the resistant of the valley walls, with rocks present along the shores, contributing to the steep, oversteepened cliffs. Erratic boulders scattered along the shores, composed of rocks transported from distant sources, further attest to the ice's far-reaching erosive power. The adjacent mountain ranges—the Maumturks and to the south in , and the Mweelrea Mountains to the north in —played a crucial role in funneling and amplifying glacial erosion, shaping the valley's linear, enclosed form and protecting it from excessive post-glacial modification.

Hydrology

Rivers and Water Flow

Killary Harbour receives its primary freshwater inputs from several rivers draining the mountainous catchments of the Partry and ranges in Counties Mayo and Galway. The Erriff River, the most significant contributor with an average discharge of approximately 8.16 m³/s, originates in the Partry Mountains and flows westward for about 33 km before entering the eastern head of the 16 km-long inlet. The Bundorragha River, draining a 48.1 km² catchment from the area, joins from the north, while smaller streams such as the Bunanakee River enter near the mouth across Uggool Beach and the Lahill River flows in at Leenane village. The Erriff provides the majority of the freshwater input, supplemented by the Bundorragha, Bunowen, and other systems, with additional contributions from submarine groundwater discharge. Aasleagh Falls marks the scenic terminus of the Erriff River's journey into Killary Harbour, located roughly 1 km north of the Galway-Mayo county border near Leenane. This picturesque cascade, dropping about 3.5 meters over rocky terrain, creates a dramatic visual endpoint for the river's flow and attracts visitors for its accessibility via a nearby bridge and trails. The falls enhance the harbour's hydrological transition by channeling peaty, nutrient-rich waters directly into the inlet, contributing to localized mixing at the eastern end. The collective freshwater inflows from these rivers profoundly shape Killary Harbour's salinity structure, establishing vertical gradients that vary with discharge rates. High river outflows, exceeding 1.7 × 10⁶ m³/day, form a pronounced at 3–10 m depth, reducing surface salinities to as low as 25.6 while preserving saline deep waters above 32, which promotes stratification. These inputs also deliver essential , influencing nutrient dynamics by retaining soluble reactive in deeper layers and elevating surface N:P ratios during stratified conditions. Seasonal flow variations in these rivers are primarily driven by the region's high , with annual rainfall in the 250 km² mountainous catchment averaging 2000–2800 mm, concentrated in wetter autumn and winter months—as of recent records up to 2023, with increasing extreme events due to trends. This results in peak discharges during heavy rainfall events, enhancing stratification and retention, whereas drier summer periods allow tidal mixing to homogenize salinities across the . Such fluctuations underscore the harbour's sensitivity to upstream hydrological changes from the encircling uplands.

Marine Characteristics

Killary Harbour exhibits a pronounced bathymetric profile characteristic of its fjard-like form, with central depths reaching 42–45 meters in the inner basin, gradually shallowed to around 5–20 meters toward the entrances at both ends. This underwater results from the drowned glacial , creating a relatively uniform deep channel along much of its 16-kilometer length, widest at over 1 kilometer near Leenaun, while narrowing at the mouths to influence local water dynamics. The tidal regime is semi-diurnal, driven by influences that propagate through the open western entrance, producing two high and low daily with ranges typically up to 4.8 meters. These facilitate significant water exchange, with strongest surface and bottom currents occurring in the narrow mouth where velocities can exceed typical inner basin flows, promoting flushing of the enclosed waters. Salinity varies seasonally and with discharge, forming estuarine conditions through the mixing of Atlantic and freshwater inflows from surrounding rivers, resulting in surface salinities dropping to 0–25 during high river flow (>1.7 × 10⁶ m³ day⁻¹) while deep waters maintain higher levels around 30, leading to stratification. Water quality remains generally high, with stratification influencing nutrient retention—such as in deeper layers—but overall solute transfer improves under well-mixed low-discharge scenarios. Currents, primarily tidal, interact with the to shape patterns, where glacial-derived silts and clays dominate the substrates, particularly in quieter inner areas, forming fine-grained deposits up to silt-rich layers from legacy glacial suspension settling. These patterns contribute to ongoing accumulation in depositional zones, modulated by tidal flushing that limits excessive buildup near the entrances.

Ecology

Flora

The flora of Killary Harbour is shaped by its position within the Connemara region, encompassing a range of habitats from mountainous blanket bogs and heaths to coastal woodlands and intertidal zones, influenced by the surrounding oceanic montane climate. Terrestrial vegetation on the encircling mountains, such as the Twelve Bens and Maumturks, is dominated by upland blanket bog and dwarf shrub heath, featuring common heather (Calluna vulgaris), cross-leaved heath (Erica tetralix), bell heather (Erica cinerea), and deergrass (Trichophorum cespitosum). These species form extensive carpets adapted to the wet, acidic, and nutrient-poor soils, with mosses like Racomitrium lanuginosum and Sphagnum capillifolium providing ground cover, alongside liverworts such as Adelanthus lindenbergianus and Bazzania pearsonii thriving in the damp, exposed conditions. Ferns, including holly fern (Polystichum lonchitis) and adder's tongue (Ophioglossum vulgatum), are scattered in bog margins and rocky outcrops, contributing to the area's species-rich understory. Near the shores, Atlantic oak woodlands occur in sheltered valleys and lower slopes, characterized by sessile oak () mixed with downy birch (), rowan (), and ash (). These woodlands support a diverse epiphytic of mosses, lichens, and liverworts, with ferns like growing as epiphytes on tree trunks. Bog plants such as purple moor-grass (), black bog-rush (Schoenus nigricans), and white beak-sedge (Rhynchospora alba) extend into lowland areas around the harbour, forming rhynchosporion vegetation in wetter depressions. Aquatic and intertidal plants in Killary Harbour include beds of eelgrass () in shallower sandy areas and extensive seaweeds on rocky substrata, such as bladder wrack () in the mid-eulittoral zone. Nutrient inputs from surrounding rivers can promote seasonal algae blooms, particularly in the during warmer months. These marine plants adapt to the harbour's strong tidal flows and moderate exposure, with seaweeds providing structural habitat in the . Unique species highlight the harbour's botanical significance, including rare Irish flora like the small white orchid (Pseudorchis albida) in rough pastures overlooking Little Killary and twayblade (Listera cordata) in nearby wooded areas. The liverwort Radula holtii, a near-threatened , grows in damp ravines along the shores, associated with species like Jubula hutchinsiae. Other rarities include St. Dabeoc's heath (Daboecia cantabrica), parsley fern (Cryptogramma crispa), and slender naiad (Najas flexilis) in adjacent oligotrophic lakes. Seasonal changes are pronounced, with heaths blooming vibrantly in summer under the mild, rainy coastal climate, while bog plants maintain year-round cover through adaptations like deep root systems and tolerance to waterlogging; winter sees reduced growth but persistent moss and liverwort activity in the humid environment.

Fauna

Killary Harbour supports a diverse array of marine fauna, owing to its fjord-like structure that blends freshwater inflows with Atlantic waters. Common seals (Phoca vitulina) and grey seals (Halichoerus grypus) frequently haul out on rocky shores and islets, while Eurasian otters (Lutra lutra), a protected species, breed along the sheltered inlets and river mouths. Bottlenose dolphins (Tursiops truncatus), Risso's dolphins (Grampus griseus), and occasionally minke whales (Balaenoptera acutorostrata) and humpback whales (Megaptera novaeangliae) transit the harbour, drawn by its rich prey availability. Basking sharks (Cetorhinus maximus), the second-largest fish species, are sighted during summer migrations, feeding on plankton in the nutrient-enriched surface waters. Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) undertake seasonal migrations through the harbour into upstream rivers like the Erriff, supporting key fisheries despite pressures from aquaculture. As of 2024, salmon stocks in the Erriff system are marginally below target, with a common estuary surplus of 10 fish advised for 2025. The harbour's coastal and estuarine habitats host notable bird populations, serving as a sanctuary for both resident and migratory species. Grey herons (Ardea cinerea) stalk shallow waters for fish, while mallard ducks (Anas platyrhynchos) and mute swans (Cygnus olor) forage in calmer bays, with the latter maintaining nationally important numbers. Ringed plovers (Charadrius hiaticula) nest on gravel shores, and common seabirds such as herring gulls (Larus argentatus) and black-headed gulls (Chroicocephalus ridibundus) breed on cliffs and islands, contributing to the area's ecological balance. Terrestrial fauna in the surrounding Connemara uplands includes (Cervus elaphus), Ireland's largest native land mammal, which roam the mountainous fringes and descend to lower slopes during winter. Red foxes (Vulpes vulpes) are nocturnal predators observed in bogs and woodlands, preying on small mammals and birds. , including seven butterfly species such as the (Aglais urticae) and (Maniola jurtina), act as essential pollinators in the and heathland ecosystems, supporting floral diversity. In 1877, Irish naturalist Emily Lawless conducted observations of near Killary Harbour, documenting interactions such as a small sheltering among the tentacles of the common () along the south shore. Her findings, published in a letter to , highlighted the abundance of and benthic forms, underscoring the harbour's role as a productive site for early marine zoological studies.

Conservation Efforts

Killary Harbour, while not designated as a site itself, lies adjacent to several European Union-protected Special Protection Areas (SPAs) and Special Areas of Conservation (SACs), influencing the habitats of qualifying species such as seabirds and from sites including Bills Rocks SPA and SPA. The surrounding landscape benefits from policy-level protections under Ireland's national planning framework, which restricts developments to preserve the area's ecological integrity and scenic value. These designations support broader conservation objectives for the region, including monitoring of migratory birds and coastal ecosystems that extend into the harbour's waters. Key environmental threats to Killary Harbour include and genetic risks from operations, particularly farming, which has led to escapes of farmed fish that interbreed with wild stocks, potentially causing genetic dilution and spreading sea lice infestations. cultivation, while generally low-impact, contributes to localized organic enrichment through waste deposition, though assessments indicate minimal effects on nearby protected populations. Tourism-related pressures, such as increased traffic and visitor waste, exacerbate habitat disturbance, while poses risks through rising sea levels and , potentially altering the fjord's and shoreline stability. in the harbour is currently rated as moderate under the EU Water Framework Directive (2016–2021 assessment), with ongoing pressures from nutrient inputs hindering full achievement of good ecological status. Conservation initiatives focus on regulatory oversight and monitoring to mitigate these threats, with Inland Fisheries Ireland (IFI) conducting regular assessments of salmon stocks, including genetic sampling to detect escaped farmed fish and their breeding potential. The Irish government, through the Department of Agriculture, Food and the Marine, enforces licensing for aquaculture sites, requiring appropriate assessments to ensure no adverse impacts on adjacent EU-protected areas; for instance, 52 mussel farm licenses cover 130 hectares in the harbour, with operations designed to avoid significant or disturbance. These efforts emphasize sustainable practices, such as longline farming that may even provide perching opportunities for seabirds. Post-2020 developments include intensified responses to incidents, such as the 2024 escape of up to 8,000 farmed , prompting IFI-led recapture operations and a 2025 scientific report confirming that a substantial portion of recaptured were mature enough to spawn, heightening genetic contamination risks. In parallel, local tourism operators have advanced sustainable practices, with entities like Killary Adventure Company earning global environmental and certifications in 2024, supporting initiatives such as coastal path development and waste reduction programs to curb from visitors. These measures align with national goals to promote eco-friendly tourism while safeguarding the harbour's role as a refuge for like and dolphins.

History

Pre-Modern History

Evidence of prehistoric human activity in the Connemara region surrounding Killary Harbour dates back to the period, with archaeological discoveries including court tombs in and a small megalith in a remote mountain glen overlooking the harbour. These findings indicate early settlements and ritual sites amid the area's rugged terrain, reflecting adaptation to the post-glacial landscape. Further evidence comes from submerged coastal along the Connemara shoreline, which has revealed hidden prehistoric remains exposed by erosion and sea-level changes. During the early medieval period, the harbour area saw Viking incursions as part of broader Norse raids on western Ireland's coastlines. was targeted in the initial phase of Viking activity starting around the , with maritime raids likely utilizing natural inlets like Killary for access. Artefacts such as a Hiberno-Norse ringed pin discovered at Omey Feichín in underscore cultural exchanges and potential settlement influences. In the later medieval era, Killary Harbour functioned as a strategic natural harbour within the territory of the O'Flaherty clan (Ui Flaithbheartaigh), Gaelic lords who dominated from the 13th to 16th centuries. The clan's domain extended from Killary Harbour southward to Galway Bay, where they maintained a network of tower houses and leveraged coastal inlets for defensive and economic purposes, including local trade and fishing amid the region's isolation. Recent excavations near Leenane have uncovered a ring barrow burial mound overlooking the fjord, pointing to continued early habitation and ritual use by indigenous communities. The name Killary Harbour originates from the Irish An Caoláire Rua, translating to "the narrow -," derived from caol ("narrow ") combined with sáile (" "), with rua denoting "" possibly alluding to seaweed-streaked waters or cliffs. Historical records from the , such as maps referring to it as "The Red Bay" or "Kelariroeh," confirm this tied to its distinctive geography.

19th and 20th Century Developments

During the Great Famine of the 1845–1852 period, significant infrastructure projects were undertaken in the Killary Harbour area as part of relief efforts to provide employment and sustenance to the starving population. One such initiative was the construction of the "Green Road," a famine relief path linking the village of Leenane in to in , running parallel to the southern shore of the harbour. Built around 1850 by local farm laborers in exchange for meager food rations, the road traversed approximately 6 miles (10 km) of rugged terrain and embodied Victorian-era charitable principles aimed at temporary alleviation rather than long-term . Though largely abandoned after the famine as nearby settlements declined, the path remains a visible remnant of the era's hardships, now overgrown with grass and used for hiking. In 1898, Irish naturalist and writer Emily Lawless conducted an informal expedition focused on the harbour's while renting a nearby. Her observations of the diverse "wriggling, writhing creatures" in the fjord's waters formed part of a broader of local , detailed in her publication Traits and Confidences. Lawless's work highlighted the harbour's rich , contributing early insights into its intertidal and subtidal habitats through descriptive essays that blended scientific curiosity with literary narrative. Following , the philosopher sought solitude in the Rosroe area at the eastern end of Killary Harbour, retreating to a modest cottage known as Quay House from April to October 1948. Accompanied intermittently by friends, including his former student Maurice O’Connor Drury, Wittgenstein used the isolated location overlooking the fjord to intensively work on his philosophical ideas, including revisions to concepts from his later period. The stark landscape provided the quiet reflection he craved after resigning from his chair, marking one of his final prolonged stays in Ireland before his death in 1951. The establishment of the in 1922 brought transformative land reforms that influenced agricultural practices and settlement patterns around Killary Harbour. The Land Act of 1923 empowered the Land Commission to compulsorily purchase large estates for redistribution to tenant farmers and landless laborers, addressing longstanding grievances from the era and earlier agrarian unrest in . In the , this policy facilitated the division of ranches in , including areas adjacent to the harbour, promoting smallholder farming over large-scale grazing and reducing absentee landlordism, though challenges like poor soil and isolation persisted.

Human Settlement and Economy

Settlements

The primary settlements around Killary Harbour are the village of Leenane, located at the head of the in , and the smaller Rosroe area on the southern shore. Leenane serves as the main hub, featuring a cluster of homes, community facilities, and access points to the surrounding landscape, while Rosroe consists of scattered dwellings and farmsteads near the water's edge. These communities are characterized by small, rural populations, with Leenane estimated at approximately 200 residents in the early 2020s. Rosroe supports an even smaller number of inhabitants, primarily families engaged in local livelihoods amid the remote terrain. Such demographics reflect the area's sparse settlement pattern, shaped by its rugged geography and historical isolation. Infrastructure in these settlements includes basic road networks connecting to the N59 highway, facilitating access for residents and visitors. Key features encompass , a modest stone structure used for and , and remnants of 19th-century famine roads that trace the shoreline, providing scenic walking paths today. These elements support daily mobility while preserving traces of past . Cultural life in Leenane and Rosroe draws from strong Gaelic traditions, with the historically spoken in the region and influencing local dialects and place names. Traditional farming practices, particularly sheep rearing on mountain pastures, remain central to community identity, as exemplified by family-run operations that demonstrate and wool processing techniques passed down through generations.

Economy and Tourism

The economy of Killary Harbour is dominated by aquaculture, which has become a cornerstone of local industry since the early 1970s. Mussel cultivation, primarily using suspended rope and raft systems, thrives in the nutrient-rich waters of the fjord, with operations like Killary Fjord Shellfish producing high-quality rope-grown mussels for domestic and export markets. These activities are regulated by the Department of Agriculture, Food and the Marine (DAFM), which issues aquaculture licences to ensure environmental compliance and sustainable practices. Salmon farming, established at sites such as Rosroe in 1986, complements this sector by rearing Atlantic salmon in open-net pens, contributing significantly to Ireland's seafood output despite occasional challenges like escapes that impact wild stocks. A notable incident occurred in August 2024 when up to 8,000 farmed salmon escaped from the Rosroe site due to a collision, prompting recovery efforts and highlighting risks to wild stocks. Traditional fishing remains a modest but enduring element of the local economy, focusing on wild and in rivers like the Erriff that feed into the harbour. Angling is regulated seasonally by Inland Fisheries Ireland, with permits supporting small-scale commercial and recreational efforts that sustain coastal communities. Agriculture on the harbour's steep, mountainous shores is limited, primarily consisting of on terraced slopes, as exemplified by operations like Killary Sheep Farm, which integrate grazing with eco-tourism demonstrations. Tourism plays a vital role in diversifying the economy, drawing visitors to the fjord's dramatic scenery along the Wild Atlantic Way. Killary Fjord Boat Tours, operating seasonally from to October, offer 90-minute cruises highlighting the inlet's , sites, and occasional sightings like dolphins, with multiple daily departures in peak season. Outdoor activities such as the surrounding hills, , , and scenic drives further attract seekers, bolstering local hospitality and guiding services. These pursuits support employment in the region, as seen in initiatives like the Killary Adventure Company's expansion, which announced plans to create up to 20 new jobs in roles in late 2024 following the 2025 opening of the renovated Sleepzone Hostel.
