Get your bait

The bait that works here comes off the shore, not out of a box.

Ragworm is dug, not bought, if you want it at its best. Estuary mud and sheltered harbour ground hold both king rag and harbour rag.

Dig the last two hours of a spring ebb, work one small patch rather than a wide area, and backfill what you turn.

Wicklow marks

Dublin Bay marks

Live ranking on Bay weather and Dublin Port tide. Howth and Dún Laoghaire pier access is field-verified; scored separately from Wicklow.

Howth East PierPierGood

Howth East Pier is the open-water side of the harbour: a public pier mark with deep wall edges, rougher pier ground, summer mackerel crowds and enough year-round variety to justify its own entry rather than folding everything into one generic Howth page. Published Dublin Bay shore notes consistently point to mackerel, pollack, coalfish, whiting, dogfish, codling, conger and grey mullet, with the east arm better suited to spinning and wall work than quiet flatfish ledgering. The setting is accessible and familiar, but it is still a working harbour edge with tourist pressure, seals, boat movement and seasonal crowding.

Poolbeg South WallPierGood

Poolbeg South Wall is the industrial Dublin Bay classic: a long walk to the red lighthouse through harbour-edge landscape, with published shore patterns for summer mackerel, pollack, coalfish, mullet, whiting, conger and occasional bass. It deserves a thick access note because access, port traffic and wall structure matter as much as species. It is not a charter or hot-water-outlet page, so confirm industrial access rules on the day.

Malahide EstuaryBeachGood

Malahide Estuary is an intermediate estuary and beach-edge mark, not a straightforward open-sand beginner venue. Published public patterns include bass, flounder, sea trout, grey mullet, smoothhound and whiting, but the fishing is shaped by tide, mud, channels, birds, boat activity, licensing rules and local access sensitivity. The first flood with a freelined sandeel is a recurring bass-style note, yet the estuary demands restraint because soft ground and fast water make casual wandering risky. Sea trout also change the legal picture: anglers must understand licence and regulation requirements before targeting or retaining them.

Dún Laoghaire East PierPierGood

Dún Laoghaire East Pier is the classic beginner-friendly south Dublin pier: paved, public, DART-accessible and deep enough along the outer wall to make summer spinning and feathering realistic without specialist shore knowledge. Published harbour patterns support mackerel, pollack, garfish, coalfish, wrasse and grey mullet, with the seaward rocky side carrying the more interesting lure water. It is easy to reach, but not empty or wild. The pier is also one of Dublin’s busiest walking routes, so the mark has to be fished as shared public infrastructure rather than as a private platform.

Balbriggan HarbourPierGood

Balbriggan Harbour is a north Fingal pier and harbour mark with a straightforward public shape but an honest uncertainty around current species strength. Published and historical notes support mackerel, grey mullet, flounder, whiting and codling, with high water over sand the basic pattern for bait fishing. Older references speak well of mullet, but present confidence is lower because commercial harbour use, fleet activity, water clarity and local pressure can all alter practical results. This entry keeps the mark live as a published option while avoiding the false certainty of claiming the harbour fishes today exactly as older reports describe.

Howth West PierPierGood

Howth West Pier is the more harbour-facing Howth option, still very accessible but with a different feel from the open east arm. It suits beginner to intermediate pier fishing for mackerel, whiting, grey mullet and conger, while the sand between the piers gives a better public pattern for flounder and dab than the rougher east-side wall. Published information also notes an Eastern Regional Fisheries Board / IFI-style "angling only" zone at the pier head, which is useful context rather than permission to ignore current harbour signs. This is a commercial harbour mark first and a leisure angling mark second.

North Bull WallPierMixed

The North Bull Wall is a long exposed stone walk from Dollymount and Clontarf into Dublin Bay, giving shore anglers access to wall edges, flats, channel influence and lighthouse-end water. Published notes cover flounder, dab, dogfish, whiting, codling, pollack, mullet and occasional bass. It is a serious public wall session, not a gentle beginner pier in rough weather.

Dún Laoghaire West PierPierMixed

Dún Laoghaire West Pier is the quieter partner to the East Pier, still beginner-friendly and public but usually better framed as a bait and mixed-bottom option than as the first-choice summer spinning wall. The point gives access to mixed and sandy ground that supports dab, whiting, codling, pollack, bass, conger and grey mullet in published Dublin Bay shore notes. It can be simple in daylight and more serious after dark. Autumn and winter night ledgering is the honest published pattern, especially when colour, tide and reduced foot traffic make bait fishing more practical.

The most frustrating fish in Ireland

Thick-lipped grey mullet are the most frustrating and most rewarding fish in Irish inshore waters. They are present in large numbers in harbours, estuaries and marinas around the Wicklow coast from May through October, you can watch them from the pier wall at Greystones on almost any calm summer day, yet getting one to take a hook is a genuine challenge that has defeated far more experienced anglers than beginners.

They are also beautiful, powerful fish that fight exceptionally hard on light tackle. Catching a specimen mullet on float gear is a significant achievement and one that keeps dedicated anglers returning harbour after harbour, session after session.

Where to find mullet on the Wicklow coast

Greystones Harbour

May to October

The inner harbour and marina holds good numbers from May. They can be seen cruising in shoals near the surface on calm days, visible fish are catchable fish, but approach requires patience and stealth.

Wicklow Town Pier

May to October

The river mouth and inner harbour by the town pier provide excellent mullet habitat. The outflow from the Vartry concentrates food and attracts large shoals in summer. The most reliable Wicklow mullet venue.

Arklow Harbour

June to September

The Avoca River mouth produces fish to specimen size in summer. Less accessible from north Wicklow but worth the journey for a dedicated mullet session.

Understanding how mullet feed

Mullet are primarily micro-feeders, grazing on algae, biofilm, detritus and tiny organisms from harbour walls, mud and weed rather than hunting individual prey items. This makes conventional bait fishing largely ineffective. The key is presenting a very small bait naturally, usually with a float, after groundbaiting to concentrate and settle the fish.

The fundamental rule: groundbait first, always. Never cast to mullet without first establishing a feeding area. Patient groundbaiting over 20 to 30 minutes before fishing is what separates successful mullet anglers from frustrated ones.

Groundbaiting method

  • 1Mix fresh white bread with a small amount of water into a paste that breaks up slowly in the water
  • 2Add pilchard oil or fish sauce, the scent trail draws fish from distance
  • 3Introduce small balls of groundbait every few minutes into a specific area, consistency matters
  • 4Once fish are feeding confidently on the surface or mid-water, introduce your hookbait into the same area
  • 5Do not rush, wait until fish are feeding actively before casting

Tackle setup

Rod

12 to 13ft match or float rod rated 5 to 15g, sensitivity is essential for detecting subtle bites

Reel

Small fixed spool loaded with 6 to 8lb monofilament, light line is non-negotiable

Float

Small waggler set at 30 to 60cm depth, the presentation must be as light and natural as possible

Hook

Size 8 to 10 fine wire, strong enough for a hard-fighting mullet, light enough not to inhibit bait movement

Best baits

Bread flake

The number one mullet bait. Pinch fresh white bread around the hook shank, leaving the flake to drift naturally. Change after every cast, stale bread loses its presentation and attractiveness within minutes.

Harbour ragworm

Small pieces on a size 10 hook is an excellent alternative, particularly when fish are proving difficult on bread. Works best when tipped with a tiny piece of bread flake.

Maggots

Two or three on a size 12 hook after groundbaiting with bread is consistent in some venues, particularly at Wicklow Town Pier where mullet become accustomed to maggot baits.

Key points

  • 1Greystones and Wicklow harbours are the main Wicklow venues, May to October only
  • 2Groundbait first, always, bread paste with fish oil before you ever cast
  • 3Light float tackle, 6lb mono, size 8 to 10 hook, waggler float
  • 4Bread flake is the top bait, fresh, changed after every cast without exception
  • 5Strike at any float movement, bites are very subtle and easily missed
  • 6Soft mouths, maintain steady pressure and use a landing net rather than lifting the fish
