The Mourne coast and Carlingford Lough

Fishing regions · Last reviewed 2026-08-28

A short, steep granite coast where a mountain range comes down to the Irish Sea, ending at a deep fjord-like lough that is also an international border.

What each one does, and what reduces it ↓

Being listed here is not permission to fish. What that means

Access, fishing rights, seasons, licences, local bylaws and permitted methods vary and can change. Check current access, permission, local regulations, closures and restrictions before you travel or fish. FishingHQ describes what the ground is and names who holds the answer; it does not hold the answer itself.

Find the authority for a jurisdiction · What FishingHQ does and does not cover

The Mourne coast is the shortest of the County Down records and the most abruptly different, because here the land behind the shore is a granite massif rather than drumlin farmland.

THE ROCK CHANGES AND SO DOES THE GROUND. North and east of here the County Down shore is greywacke and shale — flat, fractured, weed-covered reef. Along the Mournes it is granite: blockier, steeper, cleaner-edged, dropping into deeper water closer in. Boulder ground and granite ledge rather than flat scaur, and the fishing goes with it — conger, wrasse, pollack and codling over ground that is genuinely rough rather than merely uneven.

THERE ARE TWO WORKING HARBOURS ON IT. Kilkeel is one of Northern Ireland's principal fishing ports and Annalong is a smaller stone harbour of considerable age. Both are commercial rather than recreational, and both sit on a coast with almost nothing sheltered between them.

THE EXPOSURE IS THE SECOND FACT. This shore faces south-east into the Irish Sea with no protection, and the mountains behind it produce their own local wind effects. There is very little indented coast here to duck into.

AND IT ENDS AT A LOUGH THAT IS ALSO A BORDER. Carlingford Lough is a deep, steep-sided inlet running north-west between the Mournes and the Cooley Mountains — genuinely fjord-like, unlike any other water on this coast — with a narrow, shallow, buoyed entrance across which the tide runs hard. The lough is shared: the northern shore is in Northern Ireland and the southern shore is in the Republic of Ireland, and the fisheries rules on the two sides are not the same. Cranfield sits on the northern side of the entrance.

WHAT AN ANGLER SHOULD TAKE FROM THE RECORD is that this is the one place on the Northern Ireland coast where the jurisdiction can change in the middle of a body of water an angler is fishing.

What fishing here is like

A short, steep, granite coast with a mountain range directly behind it, fully exposed to the south-east and with almost no shelter along its length. Deeper water closer to the shore than anywhere else on the County Down seaboard. It ends at a deep, steep-sided sea lough with a narrow entrance, a hard tidal stream across the bar, and an international border down the middle of it.

What you can target here

One entry per fish, grouped by how you would be fishing — because the answer is a different one from the rocks and from a boat. Each entry says how strongly the sources support it and how much evidence sits behind it. This is documented quarry, not a forecast, and none of it is a statement that you may fish any particular ground.

What these strengths mean
Established quarry
Fishing sources describe this as a normal local target here, not merely as caught.
Seasonal
Well supported, and concentrated in part of the year rather than spread through it.
Places, accounts and sources are counted separately
A fish documented once at each of six marks is still documented once at each of six marks. Breadth is reported as a place count and never raises the strength, and sources are deduplicated across places so one publisher covering a whole coast counts as one. A fishery account is a source describing the fishing; a recorded catch is a report of a specific catch. They are counted apart because they are not the same evidence.

How people fish here

4 methods are recorded on the places documented here, counted from the records themselves rather than from what is practised in the country. Each opens a full guide to the technique.

  • Ledgering

    Recorded at 3 places here, over harbour wall, sea loch.

    Fishing a bait on the bottom held by a weight, with no float — the simplest way to fish at distance, in depth, or in wind.

    Documented on the same ground: Bull huss, Conger eel, Dab, European flounder, European sea bass, Pollack.

  • Float fishing

    Recorded at 2 places here, over harbour wall.

    Suspending a bait at a controlled depth beneath a buoyant indicator — the most visual, most controllable and most widely applicable method in angling.

    Documented on the same ground: Bull huss, Conger eel, Dab, European sea bass, Pollack, Atlantic mackerel.

  • Kayak fishing

    Recorded at 2 places here, over harbour wall, sea loch.

    A platform rather than a technique: quiet, shallow-draught access to water no other craft reaches, bought at the price of exposure, and a discipline where the decision not to launch is part of the skill.

    Documented on the same ground: Conger eel, European flounder, European sea bass, Pollack, Ballan wrasse, Thornback ray.

  • Spinning

    Recorded at 2 places here, over harbour wall, sea loch.

    Casting an artificial lure and retrieving it so that it moves like something alive — the most direct form of lure fishing.

    Documented on the same ground: Conger eel, European flounder, European sea bass, Pollack, Ballan wrasse, Thornback ray.

These are the methods documented at the places FishingHQ holds here. A species listed beside a method is documented on the same ground, which is not the same as being taken that way — where a source establishes the method a fish was caught on, it is stated on that place’s own page. All fishing methods.

The fishing year here

The months the records under this area actually name, tightest season first. This is “observed in these months” rather than a season: a species whose months nobody recorded is not listed, because a gap in the evidence is not a year-round fishery.

What dominates

Rock fishing from granite ledge and boulder ground for conger, wrasse, pollack and codling. Beach and shingle fishing on the short strands between. Bass lure fishing along the rougher edges. Small-boat and charter fishing out of the harbours and inside Carlingford Lough, where the sheltered water is a different proposition from the open coast outside it.

The water available

Granite boulder ground and ledge dropping into deeper water, with short shingle and sand strands between rocky sections and mountain streams entering directly. Two working harbours. At the southern end, a deep steep-sided sea lough with a narrow shallow buoyed entrance, a hard stream across the bar, and extensive shellfish beds inside it.

How the rules are structured

A border runs through this coast. Northern Ireland administers sea fisheries on the northern side; the Republic of Ireland administers them on the southern side of Carlingford Lough, and the two sets of measures are not the same. A cross-border body has responsibilities within the lough itself. Kilkeel and Annalong are working commercial harbours whose structures are operational infrastructure. Shellfish beds inside the lough are managed and are not open ground. FishingHQ does not state what any current rule is: measures, designations and local byelaws change, and the answer differs by species and by stretch of coast.

Who to ask

  • The Northern Ireland department responsible for agriculture, environment and rural affairs, which administers sea fisheries measures and marine conservation here.
  • The Northern Ireland Environment Agency and the site management bodies, where a coastal or marine designation affects access or activity.
  • The harbour authority at each port, for access to and fishing from harbour structures. Several of these are working fishing ports rather than public quays.
  • The landowner, where access to the shore crosses land in private or National Trust ownership.
  • The Republic of Ireland's sea fisheries authority, for the southern side of Carlingford Lough, where rules differ from those a few hundred metres north.
  • The cross-border body with responsibilities in Carlingford Lough, for matters inside the lough itself.

Words you will meet

The Kingdom of Mourne
The stretch of coast and country between the mountains and the sea around Kilkeel and Annalong, used locally as a name for the district. It carries the sense of somewhere set apart by the hills behind it, which is a fair description of how the coast fishes as well.

Conditions and hazards

A steep coast with deep water close in and very little shelter along it.

The granite ground drops away faster than the reef coasts to the north, so a fall here puts a person into deep water rather than onto shallow reef, and the boulder ground is awkward to climb back out of. The shore is fully open to the south-east with no indentation to duck into, and the mountains behind produce their own local wind effects that can differ sharply from a general forecast.

Carlingford Lough's entrance is the specific hazard. The bar is shallow and narrow, the stream across it runs hard, and it is a buoyed commercial channel — it is not water for a small boat to be casual in, and the sheltered appearance of the lough inside is misleading about the entrance.

Cold water applies year-round. Kilkeel and Annalong are working commercial harbours.

Who to ask before fishing any of these

FishingHQ does not know the current access position here. Sea angling access in Northern Ireland is governed by landowner permission, harbour and council byelaws, and fisheries and conservation measures, all of which change. Check the current position with the Department of Agriculture, Environment and Rural Affairs, the harbour or council, and the landowner before going. This water is tidal and transitional, so the freshwater regime may also apply above the tidal limit: FishingHQ does not know the current access position here. Angling in Northern Ireland generally requires both a rod licence from the relevant fisheries body and a separate permit for the water, and the two are issued by different bodies. Rules, seasons and permit arrangements change. Check with the Department of Agriculture, Environment and Rural Affairs, the Loughs Agency where relevant, and the permit issuer before going.

  • Cranfield and Carlingford Lough

    Sea loch · Brackish water

    A glacial fjord running fourteen kilometres inland between the Mourne and Cooley mountains, with a shallow bar across its mouth, deep water inside, extensive mussel and oyster ground, and a clean sand shore at Cranfield outside.

    The mouth takes Irish Sea swell from the south-east; the lough inside is sheltered by mountains on both sides, which also funnel the wind along its axis.

    Particular to this ground: moving water and currents, cold water shock.

    Particular to this water: Shellfish harvesting areas are classified for food safety and are opened and closed on monitoring results a gatherer cannot see. Neither cooking nor appearance removes a biotoxin. Check the current classification with the local authority before taking anything.

  • Annalong

    Harbour wall · Salt water

    A small granite harbour beneath the Mourne Mountains, built of the stone quarried above it, over granite boulder ground with deep water close inshore.

    Severe hazards of The Mourne coast and Carlingford Lough apply here: moving water and currents, cold water shock.

  • Kilkeel

    Harbour wall · Salt water

    One of Ireland's largest fishing ports, with concrete arms enclosing a dredged basin, over granite and sand beneath the seaward face of the Mournes.

    Severe hazards of The Mourne coast and Carlingford Lough apply here: moving water and currents, cold water shock.

Safety

Moving water and currents — Can cause serious injury or death

This shore faces east and south-east into the Irish Sea with several hundred kilometres of open water in front of it, so an onshore blow builds a genuine sea against rock and shingle with no shelter behind it. Waves break well up the shore on a rising tide and take people off low rock.

What reduces it: Read the fetch rather than the wind speed: a moderate easterly here does what a strong westerly does not. Fish rising tides from ground you can leave upward, and treat any mark that requires crossing low rock as closed once a sea is running.

Cold water shock — Can cause serious injury or death

Irish Sea temperatures stay low well into summer and rise little at the surface even in warm weather. Cold-water shock causes an involuntary gasp and loss of breathing control within seconds of immersion, and it incapacitates strong swimmers before any question of endurance arises.

What reduces it: Treat every mark that puts you over deep water as a mark where a fall means immersion, and dress for the water rather than the air. A buoyancy aid works in the first minute, which is the minute that decides the outcome.

Slips, trips and falls — Can cause injury needing treatment

These are working fishing ports, not promenades. Quay edges are unfenced and often high above the water at low tide, vessels manoeuvre without warning, and gear, ropes and ice are moved across the quay by machinery. A person in the water inside a harbour has vertical walls on every side and nothing to climb.

What reduces it: Treat access as the harbour authority's to give and to withdraw, and expect it to be withdrawn while vessels are working. Stay off the fairway side, keep clear of moving gear, and know where the nearest ladder and lifebuoy are before starting.

Precautions that always apply here

  • Check the tide before you go and know your exit route. Being cut off is the commonest way a shore session becomes a rescue.
  • Tell somebody where you are going and when you expect to be back.
  • Carry a charged phone in a waterproof case, or another means of calling for help.

Check the rules before you fish

Fishing laws, bylaws, access rules, seasons, bait restrictions and permitted methods vary by location and can change. Check the current rules from the relevant authority and the water you intend to fish before fishing.

Check with:

  • Current national or regional law for where you are fishing
  • Current local bylaws
  • The relevant fisheries authority
  • The landowner, club or fishery whose water it is
  • Any restrictions specific to the species or the method you intend to use
