Holyhead breakwater

Breakwater · Salt water · in Anglesey

The longest breakwater in the United Kingdom: 2.4 kilometres of limestone rubble and masonry running north-east from Soldiers Point to enclose Holyhead's harbour of refuge, with deep water on the seaward face and a sheltered basin behind.

Safety: cold water shock — can cause serious injury or death. 3 more points apply here.

What each one does, and what reduces it ↓

FishingHQ describes what this place is, not whether you may fish it. Access, permits and who to ask.

What you can catch here

Documented at this place, grouped by how you would be fishing, with how strongly the sources support each one. This is what has been written down, not a forecast, and being listed is never permission to fish.

What these strengths mean
Regular local target
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.
How breadth is counted
A fish documented at six marks is shown as six marks: breadth never raises the strength on its own. A fishery account describes the fishing; a recorded catch reports one specific catch. How evidence is weighed.

Also associated with this ground

Recorded as present here without a documented method or strength behind them.

Fish documented nearby, not here

Nothing below has been documented at Holyhead breakwater itself. Each one has been documented at a named place on the same ground, and the places are listed with it. Treat this as what the water around here holds rather than as a catch list for this mark.

Widely documented on this ground

Documented at three or more neighbouring places, fished a way this place is also fished. That is a pattern about the ground rather than about any one mark, and it is the closest this site comes to saying you will probably meet a fish somewhere nothing has been written about.

From the shore

  • Small-spotted catshark — documented at Penmon Point; Moelfre rocks; Beaumaris Pier (+1 more)
  • Whiting — documented at Moelfre rocks; Beaumaris Pier; Cymyran and Rhosneigr

Also documented at neighbouring places

One or two accounts each, on the ground around here. Enough to know the fish is caught in these waters; not enough to say anything about this place.

From the shore

How people fish it

Practised here: Sea fishing.

Methods the sources name for this ground. Each one is explained in full on its own page.

  • Float fishing

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

  • Ledgering

    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.

  • Spinning

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

The ground and the water

The ground
The longest breakwater in the United Kingdom: 2.4 kilometres of limestone rubble and masonry running north-east from Soldiers Point to enclose Holyhead's harbour of refuge, with deep water on the seaward face and a sheltered basin behind.
Exposure
Built to take the Irish Sea from the north and west, and it does. The outer face is unusable and the structure itself is closed in heavy weather.
Depth
Deep alongside the outer arm — one of the very few places in Britain where genuinely deep water can be fished from a standing position more than a mile from shore.
Tide and flow
Streams run past the head and around Holyhead Mountain, with a race off the Skerries some distance north.

Getting there

What public sources describe, last checked 2026-08-21. Car parks fill, services change and a path existing is not a path anybody may use — none of this is a guarantee of availability and none of it is permission to be anywhere.

Getting to it
The landward end sits at Soldiers Point, beyond Holyhead town, where the council's Breakwater Country Park occupies the fish that produced the stone. The park is the arrival point; the breakwater beyond it is the port authority's.
The walk in
The Anglesey Coastal Path runs through the park and on around Porth Namarch towards North Stack, and the council describes walks of varying difficulty including routes up Holyhead Mountain and to South Stack. It publishes no surface and no gradient for any of them.
Mobility
The council lists disabled toilets at the park and publishes nothing about a step-free route to the water anywhere on the site. Accessibility to the fishing is therefore not established, and a level car park is not an accessible mark.

Parking

  • Breakwater Country Park

    Public car park · Charging not established

    The council records parking at the park and states that charges may apply, without saying when or how much. It publishes no space count and no disabled bay count, so neither is recorded here.

Where this access information comes from
  • Holyhead Breakwater Country Park — Isle of Anglesey County Council (Local authority, harbour or protected-area body)Relied on for: That the council's Countryside Service manages the park, that it has parking to which charges may apply, that toilets and disabled toilets and a cafe and an information centre are on the site, and that the Anglesey Coastal Path runs through it.Passage read and verified

What is there

  • Public toilets

    Toilets and disabled toilets are listed by the council among the park's amenities. No opening arrangement is published.

  • Food or shelter

    A cafe in the converted warden's house, and an information centre with audio-visual and interactive displays. Hours are not published on the council's pages.

Through the year

Pollack, wrasse, mackerel and garfish through the warmer months; conger over the rubble year-round; codling and whiting from autumn.

The months the sources attach to each species here. Where a species carries no season it is listed underneath rather than assumed to run through the year.

Safety

Cold water shock — Can cause serious injury or death

UK coastal and inland water is cold enough for most of the year to trigger the involuntary gasp and the loss of swimming ability that decides most immersion deaths, and it does so within the first minute, long before hypothermia is relevant.

What reduces it: Wear a buoyancy aid rather than carry one, carry a means of calling for help on the person rather than in a bag, and plan on the assumption that an unplanned entry into the water is survivable only if somebody knows immediately.

Slips, trips and falls — Can cause serious injury or death

Two and a half kilometres of wet, uneven masonry above deep water with a vertical face, no exit from the water, and a very long walk back from the head if the weather changes or somebody is hurt.

What reduces it: Treat the walk out as a commitment, check the forecast for the whole intended stay rather than the next hour, wear a flotation aid, do not go alone, and turn back when water starts coming over rather than when it becomes difficult.

Tides and being cut off — Can cause serious injury or death

Tidal streams through the Menai Strait and around Anglesey's headlands reach speeds a kayak or small boat cannot make way against, with standing waves and overfalls forming at the constrictions. Slack water does not coincide with high or low tide and the window is short. Extensive intertidal flats along the strait flood rapidly and can cut off a person from behind.

What reduces it: Plan against tidal STREAM information rather than tide tables alone. Treat the Swellies as a slack-water-only proposition in any small craft. Know the exit before committing to a mark on the flats. Carry a means of calling for help and tell somebody the plan.

Worse when:

  • Spring tides, when the streams are fastest and the slack window is shortest
  • Wind against tide, which builds a short steep sea in minutes
  • Fog or failing light, when the visual cues to what the water is doing are lost

Cliffs and rock platforms — Can cause serious injury or death

Rock marks on the north and west coasts take swell generated over a long Irish Sea fetch, and a set considerably larger than the prevailing sea can arrive without warning. Falls from wet rock and being swept from a platform are the mechanisms.

What reduces it: Watch a mark for a full set before committing to it. Wear a buoyancy aid on any rock platform. Never fish a rock mark alone in swell, and treat a forecast that mentions swell separately from wind as the one that matters.

Worse when:

  • Swell arriving from a distant system in otherwise calm local conditions
  • Rising tide on a platform with a single exit
  • Night fishing on unfamiliar rock

Rules and access

FishingHQ does not know the current access position here. Shore angling in Wales is not rod-licensed, but access rights, landowner permission, local authority and harbour byelaws, national and inshore fisheries measures, and site designations all apply and all change. Check the current position with Natural Resources Wales, the harbour or local authority, and the landowner before going.

Particular to this water: This is an owned and operated structure. Whether angling is allowed on it, when, from where and on what terms is the operator's decision, is frequently seasonal, and changes without notice.

Who holds the answer:

  • Natural Resources Wales, which administers marine and fisheries regulation in Welsh waters.
  • The local authority and, where one exists, the harbour authority, for access, byelaws and shellfish classification.
  • The national fisheries authority for Wales, for sea fisheries measures, licensing and enforcement.
  • The inshore fisheries and conservation body for the area, for local byelaws, closed areas and gear restrictions.
  • The food safety authority and the local authority, for shellfish bed classification and closures, which change continually.
  • The harbour authorities and the port authority for the strait, for navigation, launching and access.
  • The maritime and coastguard agency and the lifeboat service, for safety information and rescue in an area with genuine tidal hazard.
  • The landowner, club or fishery, for permission to fish any freshwater on the island.
  • The port authority, whose decision governs access to the breakwater and angling on it.
